Atlantic Tropical Weather Outlook

ABNT20 KNHC 211750

200 PM EDT THU AUG 21 2014

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Satellite data indicate that an area of low pressure located about
275 miles east of Guadeloupe has become a little better defined
today. However, the associated shower and thunderstorm activity
remains limited and disorganized. Environmental conditions are
expected to be conducive for some development during the next day or
so, and a tropical depression could form while the system moves
west-northwestward at around 20 mph across the Lesser Antilles. The
mountainous terrain of Hispaniola could limit development during the
first part of the weekend, but conditions are expected to become
more conducive for development by Sunday when the system is
forecast to move near or over the Bahamas. Regardless of tropical
cyclone formation, gusty winds and heavy rainfall are possible
across portions of the Lesser Antilles, Puerto Rico, and the Virgin
Islands through Friday, and over Hispaniola late Friday and
Saturday. Interests in those islands and in the Bahamas should
closely monitor the progress of this disturbance. An Air Force
Reserve Hurricane Hunter aircraft is currently investigating the
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.
