Updated for reconnaissance information
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Data from an Air Force Reserve Hurricane Hunter aircraft indicate
that the circulation associated with the small low pressure area
approaching the Leeward Islands is poorly defined. In addition, the
associated shower activity has decreased during the past few hours.
The aircraft did, however, find a small area of tropical-storm-force
winds on the northeast side of the low. Environmental conditions
are expected to be conducive for some development during the next
day or so, and a tropical depression or tropical storm could still
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 expected 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 scheduled to
investigate this system again tomorrow afternoon.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.
