Heavy rain to bring flash floods to South Florida

http://www.weather.com/storms/tornado/news/severe-weather-forecast-november-30-december-6-2015

Locally heavy rain triggered flooding, including landslides and washouts in parts of the southern Appalachians Tuesday night into early Wednesday. Although the heaviest of the rain is now tapering off there, we'll turn our eyes to another potential flood threat in South Florida later this week. 

Flooding prompted evacuations along the Coosawattee River in Gilmer County, Georgia, about 80 miles north of downtown Atlanta, early Wednesday morning. Roads were closed and impassable, with landslides and washouts. A Weather Underground personal weather station near the town of Cherry Log reported over 7 inches of rain Nov. 30 through the first half of Dec. 2.

Heavy rain over mountainous terrain is frequently a flood threat, but this area is already waterlogged from a record wet November. According to the Southeast Regional Climate Center, Asheville (7.82 inches), Charlotte (10.04 inches) and Brevard, North Carolina (13.92 inches) each set record wet Novembers.

Fortunately, the cold front will finally clear the soggy Southeast later Wednesday, ending the rain. However, the front will then stall over South Florida as an injection of deep tropical moisture from the western Caribbean Sea surges northeast to meet it beginning Thursday night. This may contribute to periods of heavy rain in southern Florida late this week, which could result in some flooding.

Into Wednesday Evening: Rain Lingers in the East

• Rain will move east across the Carolinas and Northeast through Wednesday night. The rain may be locally heavy at times which may cause some localized flash flooding, as well as river flooding.
• No organized severe thunderstorm activity is expected as a relatively stable environment is forecast across the country.​

Thursday - Friday: South Florida Flood Threat

• The tail end of a cold front will bring locally heavy rain to South Florida Thursday and Friday, but severe thunderstorms are not expected. However, the rain may trigger flash flooding, particularly in urban and poor-drainage areas.
• Florida flood threat cities: Miami | Fort Lauderdale | Key West
• Forecast rainfall totals: 3-5 inches (locally 5+ inches possible)
