African Wave 95L and Mexico's Tropical Storm Polo Little Threat

By: Dr. Jeff Masters, 15:51 GMT le 20 septembre 2014

Satellite loops show that a tropical wave (Invest 95L) off the coast of Africa, a few hundred miles southeast of the Cape Verde Islands, has a moderate degree of spin and heavy thunderstorm activity. The wave is under light wind shear and over warm waters of 28°C (82°F), conditions that favor development, but the 12Z Saturday forecast from the SHIPS model predicts that shear will rise to the moderate range, ocean temperatures will cool, and the air surrounding the...

Edouard Dying; Fung-Wong Floods Manilla

By: Dr. Jeff Masters, 14:33 GMT le 19 septembre 2014

The Atlantic's strongest and longest-lived named storm of 2014, Edouard, is near the end of its life. Passage over waters cooler than 23°C (73°F) have resulted in the loss of all of Edouard's heavy thunderstorms, and satellite images show that Edouard is just a swirl of low clouds. Edouard will likely be declared dead by Saturday morning.

Earth Has its Warmest Summer and August on Record

August 2014 and the June - August Northern Hemisphere summer period of 2014 were Earth's warmest since records began in 1880, said NOAA's National Climatic Data Center (NCDC) today. NASA also rated August 2014 as the warmest August on record. August is the third time NOAA has ranked a 2014 month as the warmest on record; May and June 2014 were the warmest May and June on record (April 2014 was originally ranked as tied for warmest April on record, but has since been...

Odile's Remnants Drench Southwest U.S.; Polo Expected to Stay Offshore of Mexico

By: Dr. Jeff Masters, 15:16 GMT le 18 septembre 2014

Tropical Storm Odile is no more, destroyed by the rough terrain of Mexico and separation from warm ocean waters, after making landfall in the Northern Gulf of California 110 miles south of the Arizona border early Wednesday afternoon. The moisture from Odile lives on over the Southwest U.S., though, and has brought heavy rains of 2 - 4" over portions of Southeast Arizona, Southern New Mexico, and extreme Western Texas as of Thursday morning. Lubbock, Texas was under...

Odile Nearing the Arizona Border; Polo Nearly a Hurricane; Edouard Weakens to Cat 1

By: Dr. Jeff Masters, 15:27 GMT le 17 septembre 2014

Tropical Storm Odile is being pulled apart by wind shear as it tracks northeast at 6 mph across the northern Gulf of California. At 11 am EDT Wednesday, Odile was still a minimal 40 mph tropical storm, and had advanced within 110 miles of the Arizona border. According to NOAA's Historical Hurricane Tracks website, only two other named storms since 1949 are recorded to have maintained tropical storm strength in the Gulf of California so close to Arizona--Nora of 1997...
