Active Systems:
The National Hurricane Center is issuing advisories on Hurricane Gabrielle, located over the central subtropical Atlantic a few hundred miles southeast of Bermuda.
Central Tropical Atlantic:
Shower and thunderstorm activity associated with a tropical wave located about midway between the Lesser Antilles and the Cabo Verde Islands has increased since yesterday. Environmental conditions are forecast to become more favorable for development by tomorrow, and a tropical depression is likely to form by the middle to latter part of this week while while the system moves west-north-westward to north-westward across the central Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...high...70 percent.
East of the Leeward Islands:
A tropical wave located about 400 miles east of the Leeward Islands continues to produce disor-ganized showers and thunderstorms. Environmental conditions appear marginally conducive for slow development over the next few days as the wave moves quickly westward to west-north-westward at 15 to 20 mph. By the latter part of this week, the system is expected to slow down and turn more north-westward, and a tropical depression could form late this week when the system is over the southwestern Atlantic Ocean or near the Bahamas. Regardless of development, gusty winds and showers are expected to affect portions of the Leeward Islands late tonight and Tuesday.
