Tropical disturbance sw of Cape Verde Islands

Post by Caribbean Traveler » Sat Oct 15, 2011 8:04 am

Saturday Morning Update

Tropical disturbance forms in the deep tropics

Synopsis:
Tropical cyclones usually do not form in the area of the Atlantic this time of year. The reason is that harsh upper air conditions do not allow for development. The tropical disturbance is in the area that Cape Verde systems usually form in later August or the first half of September.

The disturbance has a circulation, but still appears weak. Convection is noted, especially on the east side. If the circulation improves in organization it will be upgraded to a tropical depression.

Currently:
At 9 am edt / ast the tropical disturbance was centered at 9.3 N / 33.0 W or roughtly 700 miles sw of the Cape Verde Islands / 1750 miles ese of Barbados. Top sustained winds are estimated at 20 mph. Movement: west 7 mph. Pressure estimated at 1008 mb.

Forecast:
Early forecast models are not very aware that a tropical disturbance even exists! Typically this time of year, tropical cyclones will recurve well east of the lesser antilles with a system like this.
