Friday, October 24, 2014
September 2014 was Earth's warmest September on record, the period January - September was tied with 1998 and 2010 as the warmest first three-quarters of any year on record, and the past 12 months--October 2013 through September 2014--was the warmest consecutive 12-month period among all months since records began in 1880, said NOAA's National Climatic Data Center (NCDC) today. NASAalso rated September 2014 as the warmest September on record. If 2014 maintains the same temperature departure from average for the remainder of the year as was observed during January - September, it will be the warmest calendar year on record. September is the fourth time NOAA has ranked a 2014 month as the warmest on record; May, June, and August 2014 were also the warmest such months on record.
Small and weak Tropical Depression Nine dissipated over Mexico's Yucatan Peninsula Wednesday night, shortly after making landfall near 8 pm EDT Wednesday October 22, 2014 on the western shore of the peninsula. Mexican radar out of Sabancuy and satellite loops show that ex-TD 9 is bringing some heavy rains to the Yucatan Peninsula, Belize, Guatemala, and the adjacent waters, and this activity will continue into the weekend. By Saturday, some of the spin associated with TD 9 may emerge over the Western Caribbean, and we should carefully watch this area on Sunday and Monday for tropical cyclone development--though none of our reliable models were predicting development in their Thursday morning runs.
The remains of Tropical Depression Nine, which dissipated over Mexico's Yucatan Peninsula on Wednesday night, were moving offshore of Belize into the Western Caribbean on Friday morning. This disturbance is being labeled Invest 94L by NHC. Belize radar and satellite loops show that 94L has only a few poorly-organized clusters of heavy thunderstorms over the Yucatan Peninsula, Belize, Honduras, Guatemala, and the adjacent waters. None of our reliable models for predicting tropical cyclone genesis were predicting development of 94L in their Friday morning runs. A trough of low pressure connected to the large Nor'easter affecting the Northeast U.S. is bringing high wind shear of 15 - 25 knots to the Western Caribbean and is injecting dry air, which is discouraging development.
