BRIDGETOWN, Barbados, Thursday July 31, 2014 – The National Hurricane Center (NHC) is reporting that Invest 93L is now a “well-defined low pressure system located about 550 miles east of the southern Windward Islands.”
According to the NHC 2 pm report, “interests in the Lesser Antilles should monitor the progress of this disturbance as it moves west-northwestward at 15 to 20 mph, and watches or warnings may be required for some of these islands later today.”
The latest NHC report indicates that “a Hurricane Hunter aircraft has begun investigating the low pressure system and preliminary reports from the aircraft indicate that this system is producing winds to near gale force.”
As of 2 pm EDT Thursday the National Hurricane Center is forecasting the 2-day and 5-day odds of development into a tropical cyclone at 70%. The system was located at 11.0N 51.4W and is moving WNW at 20 mph. Pressure is currently 1010 mb.
The weather system has been producing organized shower and thunderstorm activity during the past several hours and according to Weather Underground’s Dr Jeff Masters, may already have developed into a tropical depression.
According to Masters, all of the models “agree that 93L will arrive in the northeast Lesser Antilles Islands on Friday evening, move over Puerto Rico on Saturday evening, and approach the Southeast Bahamas and Turks and Caicos Islands on Sunday evening.”
“An ASCAT pass at 9:11 pm EDT Wednesday night showed top surface winds near 35 mph, just below tropical storm-force” says Masters.
An Air Force C-130 hurricane hunter aircraft is expected to travel into the storm this afternoon.
