Geographic Reference: 350 miles
southeast of Barbados

Movement: West-northwest
at 12 mph

Organizational Trend: Slowly
increasing

Hours: 
40 percent

Chance of Development Beyond 48
Hours: 
50 percent

Changes from Previous Forecast

The system is undergoing some
structural changes, and forecasters have relocated the center to the northwest.
Forecasters have also increased the development potential from 30 to 40 percent
over the next 48 hours.

Forecast

Forecasters expect slow
development of this large disturbance despite strong wind shear in the area
over the next couple of days. Beyond then conditions are expected to be more
conducive for development. While not yet a tropical cyclone, this system
already has winds to tropical storm strength in the squalls well to the north
and northeast of the center. If this condition persists, the disturbance would
skip the depression stage and be declared a tropical storm while moving over
the Leeward Islands.

Forecasters expect a west-northwest to northwest track over the
next few days. While near the northern Leewards, it should turn to the north
and remain east of the Bahamas and United States for the remainder of its life
span. Model guidance continues to shift a little eastward, and the center of
this system could remain just to the east of the Lesser Antilles. However, it
would still be close enough to spread squally conditions over the islands.

Expected Impacts on Land

Windward and Leeward Islands, including St. Lucia: Showers
and thunderstorms will begin to increase over the next 12 to 24 hours.
Sustained winds of 30 mph to 40 mph with gusts to 60 mph in squalls are
possible Friday into the weekend along with up to 6 inches of rain.

Virgin
Islands and Puerto Rico:
Sustained winds of 20 mph to 30 mph with
gusts possibly as high as 45 mph in squalls are possible early tomorrow through
Saturday night along with 3-6 inches of rain.

Expected Impacts Offshore

Offshore St. Lucia: Sustained
winds of 30 mph to 40 mph with gusts to 50 mph in squalls are possible from
this afternoon through tomorrow night.

Offshore Trinidad: Sustained
winds of 20 mph to 30 mph with gusts to 45 mph in squalls are possible tomorrow
through Friday.

 

Residents should pay close attention
to this system as it has the potential of being a Tropical Storm when it
