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

The National Hurricane Center is issuing advisories on Hurricane 
Larry, located over the western Atlantic several hundred miles 
southwest of Newfoundland, Canada. 

1. The northern part of a tropical wave is producing disorganized 
showers and thunderstorms over the western Caribbean Sea, and 
portions of Central America and the Yucatan peninsula.  This system 
is forecast to move into the Bay of Campeche and merge with a 
pre-existing surface trough by Sunday. Environmental conditions are 
expected to be conducive to support gradual development thereafter, 
and a tropical depression is likely to form on Sunday or Monday 
before the system moves onshore along the western Gulf of Mexico 
coast.  Regardless of development, this disturbance is expected to 
produce heavy rains across portions of Central America and the 
Yucatan Peninsula through Saturday.  Heavy rains are likely to 
reach portions of the western Gulf coast late this weekend.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...70 percent.

2. A strong tropical wave located along the west coast of Africa is 
producing disorganized showers and thunderstorms.  This wave will 
move off the coast by this evening, and gradual development is 
expected thereafter. A tropical depression is likely to form late 
this weekend or early next week as the system moves 
west-northwestward over the far eastern Atlantic near the Cabo Verde 
Islands.  Interests in the Cabo Verde Islands should monitor the 
progress of this system. 
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.
