Kirk forecast

Kirk to weaken to a trough of low pressure by Sunday

The center of Kirk is void of thunderstorms due to strong SW shear.  With this kind of shear Kirk is not expected to intensify.  It will weaken to a tropical depression by Friday night and a trough of low pressure by Sunday night.

The tropical storm force winds extend out 140 miles from the center.  The low level circulation has become exposed due to the strong SW upper level winds at 25 mph. 

Those winds are blowing all the storms well to the ENE of the center of circulation.

It will continue to move WNW and slow down just a bit on Friday.  Kirk is not expected to make it through the Caribbean as strong upper level winds will persist throughout its journey through the Central and Western Caribbean.

Tropical storm warnings are in effect for the following Countries in the Lesser Antilles.

* BARBADOS

* ST. LUCIA

* DOMINICA

* MARTINIQUE

* GUADELOUPE

Since Kirk is moving rather fast the rainfall totals are going to be in the 4-6 inch range, with some isolated amounts up to 10 inches.
