For the North Atlantic...Caribbean Sea and the Gulf of America:
Active Systems:
The National Hurricane Center is issuing advisories on Hurricane Gabrielle, located over the central subtropical Atlantic.
1. Central and Western Tropical Atlantic (AL93):
Shower and thunderstorm activity associated with a tropical wave located a little less than 1000 miles east of the Lesser Antilles continues to show signs of organization. Environmental conditions are forecast to be favorable for development over the next several days, and a tropical depression is likely to form by the latter half of this week while the system moves west-northwestward to northwestward into the western tropical Atlantic.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...high...90 percent.
2. East of the Leeward Islands (AL94):
A tropical wave is producing a large area of disorganized showers and thunderstorms, and gusty winds across much of the Windward and Leeward Islands. This wave is expected to move west-northwestward at 15 to 20 mph, spreading heavy rainfall and gusty winds into Puerto Rico and the Virgin Islands tonight and Wednesday. The system is then expected to slow down and turn northwestward when it reaches the southwestern Atlantic near the Bahamas late this week, and a tropical depression could form when the disturbance is in that region. Interests in the Virgin Islands, Puerto Rico, the Turks and Caicos Islands, and the Bahamas should monitor the progress of this sys-tem.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...60 percent.
