Disturbance off the Coast of Africa a Potential Threat to the Lesser Antilles

By: Dr. Jeff Masters, 5:57 PM GMT on July 27, 2014

An area of disturbed weather near 11°N, 31°W, about 500 miles southwest of the Cape Verde Islands, has the potential to develop into a tropical depression later this week as it heads west at 10 - 15 mph towards the Lesser Antilles Islands. Visible satellite loops on Sunday morning showed that the disturbance had only a minor amount of spin. Infrared satellite images showed that the system's heavy thunderstorm activity was modest at best, and had not changed signif...

The Record Quiet Hurricane Season of 1914: Could it Happen Again in 2014?

By: Dr. Jeff Masters, 4:08 PM GMT on July 25, 2014

This year marks the 100th anniversary of the slowest Atlantic hurricane season on record--1914, which had no hurricanes and only one tropical storm. Is it possible that the 2014 hurricane season could match 1914 for the lowest activity ever recorded, with Hurricane Arthur ending up as our only named storm? I think that is highly unlikely, even though the atmospheric and oceanic conditions in the Atlantic are looking hostile for development for the coming two weeks.<...

June 2014: Earth's 3rd Consecutive Warmest Month on Record

By: Dr. Jeff Masters, 5:22 AM GMT on July 24, 2014

June 2014 was Earth's warmest June since records began in 1880, said NOAA's National Climatic Data Center (NCDC) this week. NASA rated June 2014 a bit cooler: the 3rd warmest June on record. According to NOAA, the planet has now had three consecutive warmest months on record--April (which was tied for the warmest April), and now May and June of 2014. This is the first time Earth has experienced three consecutive warmest months on record since a four-month stretch du...

Atlantic Tropical Depression #2 Weakens to TROF as it Heads for Caribbean

By: Dr. Jeff Masters, 5:17 PM GMT on July 23, 2014

(By Steve Gregory - Substituting for Dr. Masters who is on Vacation.)

Former Tropical Depression #2 is estimated to be near 14.1N / 56.2W or about 300NM east of the CARIB, and is heading westward (290ᵒ) at 17Kts. Imagery loops along with a few surface OBS any clearly indicate TD #2 opened-up into an inverted TROF early this AM; and one with a minimum of significant convection.

MATMO Approaches Taiwan Coast as Atlantic TD#2 continues Westward

By: Dr. Jeff Masters, 3:42 PM GMT on July 22, 2014

(By Steve Gregory - Substituting for Dr. Masters who is on Vacation.)

Latest SAT and Radar imagery shows Typhoon MATMO approaching the Taiwanese east coast and is currently about 65 NM S-SE of Taipei. With a NW movement at 16 Kts, MATMO should hit the east coast within the next hour or so. Radar indicates strong convective bands have been impacting the Island for the last 4-6 hours.



Fig 1: IR imagery clearly shows MATMO has gotte...
