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

The Weather Prediction Center has issued the last Public Advisory
on Post-Tropical Cyclone Henri, moving offshore of eastern
Massachusetts.

A broad trough of low pressure is producing disorganized showers and
thunderstorms over the central tropical Atlantic about 900 miles
east-northeast of the northern Leeward Islands.  Little development
of this system is expected during the next day or two due while
it moves northwestward at about 15 mph over marginally conducive
ocean temperatures and is affected by strong upper-level winds.
Afterwards, environmental conditions are expected to become more
favorable for gradual development, and a tropical depression could
form by the end of the week while the system turns eastward over
the central Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.

A broad area of low pressure is expected to form over the
southwestern Caribbean Sea in a few days from a tropical wave
currently located over the eastern Caribbean Sea.  Environmental
conditions are forecast to be conducive for development of the low,
and a tropical depression could form late this week or this weekend
while the system moves northwestward over the northwestern
Caribbean Sea, across the Yucatan Peninsula of Mexico, and into the
southwestern Gulf of Mexico by Sunday.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...60 percent.

Another tropical wave over the far eastern tropical Atlantic located
about 400 miles south-southwest of the Cabo Verde Islands is
producing a concentrated area of showers and thunderstorms.  Some
development of this system is possible over the next several days
while it moves westward to west-northwestward at 10 to 15
mph over the eastern tropical Atlantic.  Upper-level winds are
forecast to become less conducive for development by the weekend.
* Formation chance through 48 hours...low...20 percent.
