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

The Weather Prediction Center is issuing Public Advisories on 
Post-Tropical Cyclone Henri, located inland near southern New 
England.

1. A broad low pressure area is producing disorganized showers and 
thunderstorms over the east-central tropical Atlantic more than 800 
miles west of the Cabo Verde Islands.  Little development is 
expected during the next couple of days due to only marginally 
conducive ocean temperatures.  Thereafter, however, some gradual 
development is possible through the end of the week while the system 
moves northwestward to northward at 10 to 15 mph over the central 
Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...40 percent.

2. A tropical wave over the eastern Caribbean Sea is expected to form a 
broad area of low pressure over the southwestern Caribbean Sea by 
late week.  Thereafter, environmental conditions are forecast to be 
favorable for gradual development while the system moves 
west-northwestward to northwestward over the northwestern Caribbean 
Sea. 
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.

3. A low pressure area over the far eastern tropical Atlantic about 500 
miles south-southeast of the Cabo Verde Islands is producing 
disorganized showers and thunderstorms.  Some slow development is 
possible over the next several days while the disturbance moves 
westward to west-northwestward at 10 to 15 mph over the eastern 
tropical Atlantic.
* Formation chance through 48 hours...low...10 percent.
