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

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane 
Helene, located over the southeastern Gulf of Mexico.

1. Eastern and Central Tropical Atlantic (AL98):
Showers and thunderstorms have become slightly better organized over 
the past 24 hours in association with a broad low pressure system 
along a tropical wave located several hundred miles west of the Cabo 
Verde Islands.  Environmental conditions appear favorable for 
gradual development of this system, and a tropical depression is 
likely to form during the next couple of days while it moves 
westward to west-northwestward across the eastern and central 
tropical Atlantic.
* Formation chance through 48 hours...high...70 percent. 
* Formation chance through 7 days...high...80 percent.

2. Central Subtropical Atlantic (AL99): 
Showers and thunderstorms have recently increased near the center 
of a gale-force non-tropical area of low pressure located several 
hundred miles to the east-northeast of Bermuda.  Environmental 
conditions could support the low developing some subtropical or 
tropical characteristics over the next few days, and a tropical or 
subtropical depression or storm could form late this week or this 
weekend as the system moves generally east-northeastward, remaining 
over the central subtropical Atlantic. Additional information on 
this system, including gale warnings, can be found in High Seas 
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...medium...40 percent. 
* Formation chance through 7 days...medium...40 percent.
