Ice storm cost Fort Worth about $200,000 as of Tuesday

After spending an estimated $200,000 as of Tuesday morning, the city is finally emerging from under a blanket of ice.
Transportation and Public Works crews worked 5,650 hours at a labor cost of about $125,000, Juan Ortiz, the city’s emergency management coordinator, told the City Council at Tuesday’s pre-council meeting.
They dumped more than 2,000 tons of sand and 110 tons of salt as of 7 a.m. Tuesday.
City employees worked continuously at the emergency operations center from 5:30 p.m. Thursday through Tuesday at 5 p.m., city spokesman Bill Begley said.
They’ll do another night of sanding and other road services through 7 this morning.
And after the ice fully melts or is cleared, crews will start repairing potholes and other road damage. That cost that has not been estimated, Begley said.
“To say this was a major event would be understating it,” Mayor Betsy Price said.
“There is always room for improvement and I hope you will do some lessons learned and work on things, because on a major event like this you can take the best and build on it and go from there.”
City employees, many of whom brought bedrolls to stay the night at the emergency center over the weekend, did an amazing job monitoring the weather, Price said.
However, she said, she thinks city officials need to look further into some problems, such as the “cobblestone ice” that developed when ice melted slightly when sanded and then refroze.
“Could we have gotten involved TxDOT here sooner? Is it worth purchasing equipment? ‘Probably not’ would be my response at this point because we don’t have this kind of event very often, and that is expensive equipment, but is there a way to modify equipment we already have?” Price said after the meeting. “We just need to look at the ‘what ifs.’”
Also, she said, the emergency shelter for the homeless at Bertha Collins Community Center did not have a firm plan for providing food, which is something that could have been managed ahead of time.
The shelter housed between 31 and 43 people a night, starting Friday night. The emergency shelter is expected to be open again Tuesday night, Ortiz said.
The Jingle Bell Run, which was scheduled for Saturday but was canceled, donated 5,000 water bottles and fruit to the emergency shelter. The run, which benefits the Arthritis Foundation, had a goal of raising $250,000 but was about $100,000 short Tuesday afternoon, according to their website.
Central Market and Albertsons grocery stores also donated food to the shelter.
Police responded to an 18 percent increase in overall calls and the fire department responded to 52 percent more medical calls and 111 percent more fire calls, Ortiz said.
Reports of injuries from falls were up 220 percent over the weekend.
“We had icy conditions all over the city,” Ortiz said. “No place was left uncovered.”
Assault reports were down 22 percent, Ortiz said, probably because fewer people were venturing out to public places.
The initial cost estimates do not include overtime from the police and fire departments, and the costs are expected to rise as city employees continue to work around the clock and use costly materials to clear the ice, Begley said.
The city also gave more than 500 cots to DFW Airport, which had to accommodate about 4,000 stranded travelers at the highest point.
Sean Donohue, the new chief executive of DFW Airport, joked at the council meeting that the airport “bought every cot in the Metroplex area,” and appreciated Fort Worth’s contribution.
“I can tell you, I would take a foot of snow over 3 inches of ice any day,” Donohue said.

Helping the National Weather Service improve its performance

Andrea Bleistein is playing a critical role in helping the agency institute this new roadmap for change—a plan designed to improve the way the weather services does business and enhance its ability to save lives and property.

As a manager supporting the agency’s Weather-Ready Nation initiative, Bleistein assists and, in some cases, prods the staff to implement changes outlined in the long term plan. This includes making new investments in science and technology, creating pilot projects to provide better assistance to states and localities, coming up with innovative ways to improve communication through the use of social media, identifying new research to meet pressing needs and finding ways to support the workforce.
“I’m a facilitator in a lot of ways. I’m helping coordinate the changes to make us more relevant in the future,’ said Bleistein. “We take feedback at the local level. We make recommendations to senior executives. When people are creating program plans for the year, we look and say, ‘You are not going where you should be going and you might reassess the process.”
Bleistein said her job may involve helping to set up, evaluate and expand new initiatives such as dispatching a weather service meteorologist to a city bracing for a severe storm. Or she said it might mean working with staff to make sure that new technology is working and meeting intended goals.
Chris Strager, Bleistein’s supervisor, said his colleague “thinks about the big picture” while attending to the details. He said she is aware of how things work at headquarters and at the weather’s service’s 122 forecast field offices, and is able to communicate up and down the line.
“That’s what impressed me so much about her. She has the rare ability to do that at such an early age,” Strager said.
While each initiative and project has specific objectives, Bleistein said, the bottom line is to improve the weather forecasting so that governmental officials, private business and the public are armed with information that allows them to respond with the best course of action.
“We want them to understand not only what the weather is going to do, but we’re helping them identify what are their risks from a storm or flood,” said Bleistein.
To hone the weather service’s forecasting and response methods, Bleistein helped set up six community-based pilot projects in the Gulf Coast, the South and the mid-Atlantic. The projects are testing communication and support for urban and coastal areas and looking at how regional and national levels make decisions on responding to the impact of severe weather.
During a recent rash of tornados, Bleistein said the weather service used Twitter and other social media to provide public alerts, helping people “take preparedness activities earlier to avoid danger.” She said her office hopes to build on this success.
Bleistein’s interest in weather forecasting started a long time ago. Her father was the type who would see a thunder storm coming and beckon Bleistein to come open the windows and watch as it blew in. “I was one of those kids raised by a dad really into amateur radio and I listened to weather with my dad during a storm,” she said.
As a young girl, she reported the weather at her school bus stop and debated the day’s forecast with a friend who watched a different television meteorologist.
Bleistein started in college as engineering major, but once she switched to meteorology, she said, she “never looked back.”

Chicago Weather: City Sees Earliest Sub-Zero Temperature In 18 Years, More Snow Coming

chicago weather sub-zero
It's so bitterly cold outside in Chicago, it might come as a surprise to some to learn that it's technically still fall.
Temperatures overnight Tuesday dipped as low as 1 degree below zero at O'Hare International Airport, marking the first time that's happened this early in the season since 1995, the Chicago Sun-Times reports. That's 18 years ago.
While the temperature quickly returned above zero again, as of 7 a.m. the wind chill was 9 degrees below zero, according to the Chicago Tribune.
Making matters worse, AccuWeather reports snow may return to the Chicago area Wednesday morning.
The snow is expected to begin just after midnight Wednesday morning and the heaviest snowfall will likely fall between 5 and 8 a.m., just in time for the morning commute. CBS Chicago reports between 2 and 4 inches of snow could fall.
The city won't get anything resembling a warmup until Friday, when temperatures will rise slightly but still aren't expected to pass 30 degrees, the Tribune reports.

L.A. cold snap, high winds to peak today; milder weather on tap

L.A. cold snap, high winds to peak today; milder weather on tap

A burst of gusty winds that hit the Los Angeles region Tuesday morning is expected to give way to calmer conditions and warming temperatures.
Areas in eastern Ventura County and western L.A. County felt the brunt of the frigid temperatures amd high winds hit 65 mph in some areas, said Kathy Hoxsie of the National Weather Service.
The high winds had downed trees and power lines Tuesday morning and were expected to make driving difficult along the 5, 118 and 210 freeways, according the weather service. Thousands of customers from Granada Hills to Inglewood also temporarily lost power, although crews were still investigating the cause.

A wind advisory remained in effect for much of Los Angeles and Ventura counties, with gusts of up to 55 mph possible in local mountains.
“It’s peaking now,” Hoxsie said of the wintry weather. “And this weekend, we may have above normal temperatures.”
Temperatures have plummeted into the 30s and low 20s since last week as a low pressure system from Canada pushed down into the Southwest, causing frost and freeze advisories. The cold snap was also blamed for the deaths of four homeless people in Northern California.
But conditions are expected to warm up later in the week. Temperatures could rise into the 60s — even low 70s — this weekend as the weather system continues to make its way across the county, Hoxsie said.
Although daytime temperatures are expected to warm up, forecasters warned that late nights and early mornings could still bring bitter cold conditions, so the public should take extra care of pets, livestock and vegetation.

Wicked Storm from Russia ‘Attacks’ Israel with Rain and Snow

Israelis have prayed for rain in a dry November and now are getting the dividends in spades, thanks to a rare early winter storm “from Russia with love.”

 A wicked and rare early winter storm plowed into Israel Wednesday, and weather forecasters predict between four and eight inches of rain will fall in the north, with gale force winds and possibly snow in Jerusalem and the higher hills of Judea and Samaria. Snow is rare in Israel in early December, and predicting the white stuff in the country is as tricky as forecasting anything else in the Middle East. A tiny shift in the winds often moves a weather system towards or away from land, and a change of one or two degrees in the temperature can spell the difference between rain and snow. This week’s system is a woozy, and the only questions are whether the rains will be drenching or extremely torrential, and if snow will accumulate in Jerusalem. Rain fell in central and northern Israel last week after a dry November, and some communities in the western Negev received as much as four inches of rain. The Kinneret began to rise for the first time since last spring, but that is only a sneak preview of what is in store for the country from today through Sunday. Before it is all over, more than three feet of snow is expected to have fallen on the upper slopes of the Hermon, which would allow for a very early opening of the ski season next week, weather permitting. The Ministry of Agriculture predicts that up to seven inches of rain will fall in the northern Golan Heights, six inches in the Haifa area, 2-3 inches on the Kinneret, 5-6 inches around metropolitan Tel Aviv, 2-3 inches in the northern Negev and more than half an inch in the parched Arava desert. The storm is rare in its expected intensity and length because it is headed from Russia, via the Black Sea, an unusual occurrence in early December. Meteorologist Tzachi Waxman of Meteo-Tech said, “A cold wave like this is exceptional for this time of year and usually occurs in January and February.” Torrential rains will raise the level of the Kinneret dramatically once run-off begins from mountain streams. The downside of the storm will be the usual flooded streets, traffic jams and power outages resulting from electric poles and wires downed by heavy winds and from heavy demand for power by everyone using electric heaters to stay warm. Air traffic at Ben Gurion may be disrupted, which could knock out the schedule of U.S. Secretary John Kerry who is to land in Israel on Wednesday. With a bit of luck, good or bad depending on your view, he might not be able to land at all. Heavy rains and strong winds, which may reach gale force velocity, began falling in the northern Negev late Tuesday. Weather maps indicate a rare phenomenon for this time of year will occur on Wednesday, when rain is expected to fall over the entire country, from the northern border to Eilat. Snow on Wednesday night will cover Tzfat (Safed) and other higher elevations in the northern Galilee and the Golan Heights, and it will continue on Thursday, with occasional thunderstorms throughout the country. There is a chance of snow in Jerusalem and the mountains in Judea and Samaria and the Negev on Thursday and a higher probability that snow will fall on those areas Thursday night and Friday. However, there is no assurance that the snow will accumulate below altitudes of 2,800 feet, the height of most of the highest areas in Jerusalem. Parts of Gush Etzion and the southern Hevron Hills are as high as 3,000 feet, where accumulation is more probable. Flash floods will smash through the Judean Desert and Arava. Private weather forecasters predict that the storm will continue to pummel Israel on the Sabbath before weakening late in the day. It will be extremely cold Saturday night, with possible sub-zero temperatures in higher elevations.

As Dallas storm eases grip, agencies prepare for next one

A student walked to class Tuesday at Sunset High School in Dallas on yet another chilly day -- but the sun was out and helped melt some of the remaining ice from last week's storm.
With the ice gradually disappearing from North Texas highways and electric power restored after last week’s deadly storm, the agencies tasked with keeping the region running began figuring out how they can do better the next time.
“Everybody’s asking, ‘Didn’t you learn anything from the Super Bowl?’” said Tony Hartzel, a spokesman for the Texas Department of Transportation in Dallas. “We did start using plows, and we’re using straight salt on the ice in some areas.
“We used everything in our arsenal from the beginning. We pre-treated, put out sand and salt and magnesium chloride, and in Denton we used straight salt after we scraped and plowed Interstate 35,” he said. “But we were expecting a quarter- to a half-inch of ice and we got a lot more. We tackle it as hard as possible, but when you get that much in that amount of time, it’s tough.”
For Oncor, the region’s electric provider, the first few days of the storm were spent in a furious effort to restore power.
“At our peak on Friday, we had 270,000 outages,” said spokeswoman Jeamy Molina. “And Saturday and Sunday, we saw an additional 50,000. Our crews were on 16-hour shifts, and we had more than 5,000 Oncor employees, contractors and mutual utility partners from Texas and seven other states working on this.”
The last few hundred properties in the Dallas-Fort Worth area without power had it restored Tuesday, she said, though crews are still working on areas farther north that took a harder hit from the storm.
Numerically, the progress was impressive, restoring more than a quarter-million customers’ power in about five days.
“We know that doesn’t seem fast to customers who had their power out for extended periods,” Molina said. “But we did everything we could and worked round the clock to make sure customers could have power restored as quickly as possible.”
Dallas Area Rapid Transit experienced the largest light-rail shutdown in agency history after the ice kept trains from running for three days. The system reached full service Tuesday afternoon when the last shuttered leg, the Blue Line from Dallas to Rowlett, opened to passengers.
The ice storm has been linked to at least five deaths in Dallas-Fort Worth.
Kayla Alejandra Gawalek, a 21-year-old Lewisville woman, died early Saturday after her pickup slid off an icy bridge on I-35 and into Lewisville Lake. She was on her way to work in Denton.
Crews recovered the truck with Gawalek’s body inside several hours later.
Sergio Diaz Jr., 26, of Rockwall, died in a car crash early Sunday on Royal Lane near Preston Road in Dallas.
A woman in her mid-40s was found dead in a South Dallas parking lot on Martin Luther King Jr. Boulevard near the S.M. Wright Expessway on Monday, an apparent victim of the freezing weather.
A 91-year-old Fort Worth man, Therman Harris, was found dead early Monday in southwest Fort Worth, near his SUV, about 13 miles from his home. The Tarrant County medical examiner will determine the cause of death.
An Arlington man, 29-year-old Chase Brandenburgh, died Thursday when his car slammed into a tractor-trailer on Interstate 20 in icy conditions on Thursday.
The core of the problems across North Texas was the storm itself. Forecasts Thursday called for a quarter to three-quarters of an inch of ice from bands of freezing rain. Instead, much of the Dallas area awoke to 2, 3 or even 4 inches of sleet, freezing rain and rain that froze solid.
“We were thinking more freezing rain, and it ended up being more sleet than freezing rain,” said Jesse Moore, a meteorologist with the National Weather Service in Fort Worth.
“It’s really important to know exactly how the atmosphere looks, how deep the cold air will be,” Moore said. “We had surface temperatures at or below freezing, and temperatures in the upper 40s and 50s as you went up into the atmosphere, and then colder temperatures above that.
“That’s what makes winter weather forecasting so much more difficult here — our temperatures are usually borderline,” he said. “We had some freezing rain, and it went back and forth several times, but sleet was the primary precipitation.”
Or as Hartzel put it, “Six inches of snow would have been much easier to handle than six inches of sleet, freezing rain and ice.”
But Tuesday’s sunny skies provided an antidote to all the ice, at least for a while.
“Even when temperatures are 30 to 32, even in the upper 20s, you get melting with sunshine,” said Moore of the National Weather Service. “So we’re seeing melting” even though temperatures remained cooler than expected.
But with sub-freezing temperatures early Wednesday and Thursday, any wet spots on the roads will ice over again, Moore said. Temperatures Friday should remain above freezing, with highs reaching the 50s

China says poorly prepared to fight impact of climate change

(Reuters) - China is poorly prepared to tackle the impact of climate change that presents a serious threat to the country, thanks to a lack of planning and public awareness, the government said on Monday.
The world's most populous country already faces challenges from weather extremes, with 2,000 people dying on average each year since the 1990s in natural disasters that are set to get worse, China's powerful economic planning agency said.
"Our country is a developing nation with a large population, complex climate conditions and a weak environment (situation)," the National Development and Reform Commission said in a report.
"Climate change is already a serious threat to food, water, ecological and energy security, and to people's lives and property," it added.
"The mission to deal with climate change is very arduous, but knowledge in society and ability to do this are weak across the board."
China is seeing more droughts in its northern region, with typhoons arriving earlier, wetlands drying up and sea levels rising, said the document, published in coordination with several ministries, including the Agriculture Ministry.
"In the future the rising trend of temperatures will become even more obvious, there will be even more unfavourable impacts (from climate change), and if effective measures are not taken the losses from disasters caused by extreme weather will be even more serious," the agency added.
Government steps to mitigate climate change range from building more reservoirs, providing better protection to forests and wetlands to improving weather warning systems, but the overall picture was not optimistic, the planner said.
"Although our work at dealing with climate change has achieved some successes, basic abilities have yet to be raised up, and there are many weak links in our work," it added.
China was unable to protect basic infrastructure, such as power and water supplies, from extreme weather events, and flood prevention efforts need to be spruced up, it said.
A coal-dependent manufacturing base has made China the world's biggest contributor to climate change, while high and rising local air-pollution levels have sparked widespread public anger nationwide.
In recent months, officials have outlined new policies to fight the problem, on top of steep renewable energy targets in the current five-year plan.
China's pollution is expected to continue growing well into the next decade, albeit at a slower pace, as it has little choice but to rely on fossil fuels to develop its western interior.

Icy weather sends Texas' December power use to new record

Dec 9 (Reuters) - Freezing weather across Texas set two December power use records over the weekend as residents worked to stay warm, according to preliminary data from the state's power grid operator.
Power demand on Friday reached 51,484 megawatts in the hour ending at 7 p.m. CDT (0100 GMT), surpassing the December 2011 record of 50,100 MW, according to the website for the Electric Reliability Council of Texas (ERCOT), the state's primary grid.
On Saturday, that record fell as power consumption rose to 52,279 MW at 7 p.m., up 4 percent from the 2011 record.
ERCOT has now recorded the third monthly power demand record this year.
Electricity use in Texas has been growing faster than generation is being built, shrinking the region's reserve margin and increasing the prospect of rolling outages when supplies are stretched, the grid operator has warned.
Over the weekend, a winter storm barreled as far south as Texas, paring 20 to 35 degrees Fahrenheit from normal high temperatures in Houston, San Antonio and Dallas, Texas' largest cities.
An ice storm covering much of North Texas kept temperatures below freezing (0 degrees Celsius) from Thursday night into Sunday, according to AccuWeather.com.
Monday's high in Dallas is forecast to reach 36 degrees F, 20 degrees colder than normal. The city's low will be 24, 15 degrees F below normal, AccuWeather.com said.
A slow warming trend is forecast for the state through the week, paring electric use, according to ERCOT forecasts.
Real-time power prices in the state indicated ample power supplies were available over the weekend.
Texas normally sees peak cold-weather power demand in January or February. December's record power demand has surpassed the grid agency's winter forecast of less than 50,000 MW under normal weather conditions.
ERCOT has set three straight monthly power records.
On Nov. 25, power use reached 46,931 MW, surpassing a November 2006 record of 45,143 MW.
Power use in October reached 54,710 MW, beating the 54,102 MW record set in 2002, according to ERCOT's website.
ERCOT's winter consumption record is 57,265 MW set on Feb. 10, 2011 during an extreme statewide cold spell. The state's all-time peak use of 68,379 MW occurred in August of the same year during a prolonged heat wave and drought.
One megawatt can power about 500 homes during mild weather conditions and about 200 homes during high-demand summer months, ERCOT said.

Power producers in Texas include Luminant, a unit of privately held Energy Future Holdings, NRG Energy , Calpine Corp, NextEra Energy and Exelon Corp.

For days, temperatures have plunged across a large portion of the United States, accompanied by a storm system that's brought sleet, snow, ice or a combination of all three. The weather has been a factor in several deaths and has caused treacherous travel conditions and the cancellation of thousands of flights.
ARKANSAS
Temperatures in Arkansas were forecast to remain in the upper 20s or mid 30s today, with a slight chance of light snow or sleet in the evening hours, but no National Weather Service watches or warnings were in effect.
Road conditions in the state had improved since Friday's wintry storm although some roads remained icy in Little Rock and in northern parts of the state. Many schools remained closed.
CALIFORNIA
Citrus farmers in California's Central Valley dodged the brunt of the seemingly never-ending winter storm. They used wind machines over the weekend to prevent crop freezes when temperatures dropped into the upper 20s.
CONNECTICUT
Slippery roads led to a crash involving about 20 vehicles in southwestern Connecticut Sunday night, closing part of Interstate 95 for about two hours. State police said early Monday that six people were injured, none of them seriously.
The National Weather Service said snow changing to sleet and freezing rain was expected through Monday morning, with up to an inch of snow and ice possible in southern Connecticut and yet more expected further north into New England.
ILLINOIS
Football fans will need to bundle up when the Chicago Bears host the Dallas Cowboys tonight. The mercury is expected to drop throughout the day and forecasters said wind chills will fall below zero when the teams face off. The National Weather Service said the wind chill in some parts of northern Illinois could sink to 15 below zero Monday night.
About three inches of snow fell at O'Hare International Airport on Sunday and flurries continued today.
INDIANA
Freezing rain across much of central and northern Indiana overnight coated roads with ice and contributed to many crashes. State police say a woman died when her SUV spun out and was struck by a car and a semi Sunday evening on a snow-slick Interstate 65 near Roselawn in northwestern Indiana. Dozens of schools were closed or were opening later than usual.
The freezing rain ended early today but officials warned that slick conditions could continue.
MARYLAND
Utilities said more than 19,000 customers were without power earlytoday in Maryland due to the wintry storm. Baltimore officials cancelled the mayor's annual Christmas parade Sunday because of snow and dangerous road conditions.
MASSACHUSETTS
Massachusetts commuters faced a light covering of snow this morning. Much of the state experienced at least a dusting of snow, but that was expected to turn over to rain as the day progressed, with temperatures at about 40 degrees.
NEW HAMPSHIRE
Light snow fell over much of New Hampshire making for slick roads and some school delays this morning. A couple of fender-benders were reported in the Lebanon and Manchester areas. Several flights scheduled to take off from Manchester-Boston Regional Airport were delayed.
The National Weather Service says the light snow is going to mix with sleet or freezing rain as warmer air moves in across southern sections of Maine and New Hampshire. Total snow amounts through the afternoon are expected to be in the range of one to 3 inches.
NEW YORK CITY
Police said slippery road conditions contributed to a 10-car pileup in Yonkers north of the city late Sunday but there were no serious injuries.
Some schools in Westchester, Putnam and Orange counties said they would be open Monday 2 hours later than usual due to the wintry weather.
OKLAHOMA
Forecasters said light snow was possible in northern Oklahoma as another round of wintry weather made its way through the state and cold temperatures were expected to persist throughout the week. Many schools remain closed today.
PENNSYLVANIA
A storm system that blanketed Pennsylvania with several inches of snow began to leave the state Monday morning. The flakes changed to rain in Philadelphia, making for slushy streets downtown. City schools were expected to operate on a normal schedule, and transportation officials said regional rail was operating on or close to schedule.
TEXAS
All major highways were reopened by late Sunday after a major storm last week immobilized much of North and West Texas. Nonetheless, Fort Worth-based American Airlines and American Eagle canceled 700 flights today, mainly in North Texas. Utilities said nearly 22,000 homes and businesses were still without power.
WASHINGTON, D.C.
Many side streets were icy after a light freezing rain fell early this morning. Federal agencies were open but workers could arrive up to two hours later than normal due to the freezing rain.
The Metropolitan Washington Airports Authority said many flights were delayed or canceled at Dulles International and Ronald Reagan Washington National airports. Baltimore-Washington International Thurgood Marshall airport also had canceled flights.
The weather service forecast that freezing rain and drizzle would continue in the region, with accumulations of up to a quarter inch of ice, and a winter storm warning was in effect until 10 a.m.
WISCONSIN
Snow plow drivers worked overnight and by this morning, the main roads/interstates were in good shape in Milwaukee County. Snow contributed to at least two fatal accidents and numerous pileups that injured dozens of people in southern Wisconsin on Sunday. The Milwaukee County Sheriff's Office described conditions on the interstates as "extremely slippery and dangerous."

Custom cameras catch weather clues, beauty in Utah snowflakes


These fluffy snowflakes, known as aggregates, form when snow crystals collide with other snow crystals. Many of these flakes also show some riming, or an icy coating.

Custom cameras catch weather clues, beauty in Utah snowflakes
U. research » Images aid forecasters and avalanche center, offer look at “a zoo of very odd looking creatures.”
First Published Dec 07 2013 04:27 pm • Updated 45 minutes ago
They say every snowflake is unique.
University of Utah researchers test that theory every time it snows at Alta Ski Area in Little Cottonwood Canyon.
Multi-Angle Snowflake Cameras — constructed at the U. and now being provided to other weather-related researchers — placed at Alta automatically kick on when snow starts to fall and record images until it stops.
"Since April of 2011 we have obtained views of snowflakes that I don’t think have ever been seen before," said Tim Garrett, a professor in the department of atmospheric sciences and lead researcher in the project. "We are seeing things that really are new and exciting. We are opening up scientific questions that we had not thought about before."
Garrett is not the only one who gets to see the results. TheSnowflake Showcase page on the Alta website allows anyone with an Internet connection to get up close and personal with flakes before they become part of Utah’s Greatest Snow on Earth.
Bruce Tremper, director of the Utah Avalanche Center, has the page bookmarked and uses the images to help form avalanche-warning reports.
"I love the Snowflake site, and I like to look at it to see what kind of crystals are falling. The site is especially useful during big storms when we can get avalanches breaking within the new snow," Tremper said. "For instance, if the storm starts out with [flakes called] stellar plates, then switches to graupel — that Styrofoam ball kind of snow — then you know that the density has gone way up and you have what we call ‘upside-down’ snow, meaning denser snow on top of lighter snow, which can cause avalanches."
Garrett came up with the idea for taking pictures of snowflakes during a ski day in the Cascade Mountains in the late 1990s. He was riding a lift with a fellow graduate student who was a "true meteorologist."
"He pointed out to me the incredible variations in snowflake shape over very short distances as we went up the ski lift," Garrett recalled.
Being able to document the kinds of snowflakes and how fast they are falling allows better weather forecasting by characterizing the snow in clouds.

Garrett had tried to measure clouds and snowflakes from an aircraft during research in the Arctic, but that proved difficult and expensive.
Equations used to predict how fast certain kinds of snowflakes fall were created by researchers in the early 1970s on the Cascade Mountains. They collected flakes on Saran Wrap and took 300 pictures while recording how fast similar flakes fell.
"It was painstaking and, as you can imagine, as soon as one of the snowflakes fell on the surface, it collapsed on its own weight and that was how the picture was taken," Garrett said. "It’s not the same thing as taking one free-falling in the air."
Technology created by Cale Fallgatter, then a master’s degree graduate in mechanical engineering at the U., has created "a million snowflake pictures" in a single winter.
It took Fallgatter three years of building prototypes before the Multi-Angle Snowflake Cameras (MASC) were posted at Alta.
Fallgatter has since created Fallgatter Technologies to produce more MASC devices. Garrett said one MASC is at the Mammoth Ski Area in California and is helping the U.S. Army study avalanches. At least two other MASC devices are being used for climate studies — one in Alaska and one on the Greenland ice sheet.
While the cameras record important data and provide vital weather research, Garrett often finds himself clicking on the Snowflake Showcase webpage to see the endless variety of patterns.
"The shapes are just so beautiful, interesting and exciting. My wife sometimes calls herself a snowflake widow," he said. "We have this ingrained conception that snowflakes are these six-sided creatures that possess some symmetry. Rather what we see in snowflake shapes is a zoo of very odd looking creatures that are almost impossible to define."
Flake-aholics who just can’t get enough from the website may be pleased to hear that work is being done on an iPhone app to help them get their fix.
