1. Central Tropical Atlantic (AL92):   An area of low pressure located over the central tropical Atlantic continues to produce some disorganized shower and thunderstorm activity.  Environmental conditions appear marginally

conducive for some slight development during the next day or two while the system moves west-northwestward at 5 to 10 mph over the central tropical Atlantic.  The disturbance is expected to reach an area of stronger upper-level winds on Friday, likely ending its chances for development.

* Formation chance through 48 hours...low...30 percent.

* Formation chance through 7 days...low...30 percent.

 

2. East of the Leeward Islands (AL94):  A small but well-defined area of low pressure located several hundred miles to the east of the Leeward Islands is producing  limited shower and thunderstorm activity. The proximity of dry

air near the system is expected to limit additional development over the next couple of days before environmental conditions become even less conducive by this weekend while it moves slowly west-northwestward.

* Formation chance through 48 hours...low...10 percent.

* Formation chance through 7 days...low...10 percent.

 

3. Offshore the Southeastern U.S. over the Western Atlantic:  In a few days, a non-tropical area of low pressure could form along a residual frontal boundary a few hundred miles off the southeastern U.S. coastline. Thereafter, some subtropical or tropical development is possible during the early part of next week while the system drifts to the north or northwest. 

* Formation chance through 48 hours...low...near 0 percent.

* Formation chance through 7 days...low...30 percent.
