An area of disturbed weather located near 10°N, 33°W at 8 am EDT Monday, about 500 miles southwest of the Cape Verde Islands, was designated Invest 93L by NHC early Monday morning. This disturbance is a more serious threat than Tropical Depression Two of last week, and has the potential to develop into a strong tropical storm before reaching the Lesser Antilles Islands on Friday or Saturday. Visible satellite loops on Monday morning showed that the disturbance had...

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...

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 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...

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.
