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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Storm Helene, located over the northwestern Caribbean Sea.

1. Eastern and Central Tropical Atlantic (AL98):
A broad low pressure system associated with a tropical wave located 
west of the Cabo Verde Islands continues to produce disorganized 
shower and thunderstorm activity. Environmental conditions appear 
favorable for gradual development of this system, and a tropical 
depression is likely to form in a few days while it moves westward 
to west-northwestward across the eastern and central tropical 
Atlantic.
* Formation chance through 48 hours...medium...50 percent. 
* Formation chance through 7 days...high...80 percent.

2. Central Subtropical Atlantic (AL99): 
A non-tropical area of low pressure is currently located several 
hundred miles to the northeast of Bermuda. The system is currently 
producing winds up to storm force, and environmental conditions 
could support some subtropical or tropical development over the next 
several days as the system moves generally eastward, remaining over 
the open waters of central Subtropical Atlantic. Additional 
information on this system, including storm warnings, can be found 
in High Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...10 percent. 
* Formation chance through 7 days...low...20 percent.
