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 portion of a tropical wave is producing disorganized 
showers and thunderstorms over Honduras, the western Caribbean Sea, 
and portions of the Yucatan peninsula.  This system is forecast to 
move into the Bay of Campeche and merge with a pre-existing surface 
trough located over the southwestern Gulf of Mexico by this weekend. 
Environmental conditions are expected to be conducive to support 
gradual development, and a tropical depression is likely to form 
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 through Saturday.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...70 percent.

2. A strong tropical wave is expected to emerge off of the west coast 
of Africa by tonight.  Environmental conditions are forecast to be 
conducive for gradual development thereafter, and 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.
