For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Hurricane
Sam, located several hundred miles east of the northern Leeward
Islands.
1. Satellite images indicate that showers and thunderstorms continue
to become better organized in association with an area of low
pressure located several hundred miles south of the Cabo
Verde Islands. If the current trends continue, advisories will
likely be initiated on a tropical depression or tropical storm
later today. This system is expected to move west-northwestward at
10 to 15 mph over the eastern Atlantic during the next several
days. Additional information on this system, including gale
warnings, can be found in High Seas Forecasts issued by Meteo
France.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.
2. Showers and thunderstorms remain disorganized in association with a
a trough of low pressure located several hundred miles southwest of
the Cabo Verde Islands. Development of this system appears less
likely due to the interaction with the larger low pressure area
located to its east. The system is forecast to drift
west-northwestward over the tropical central Atlantic during the
next few days.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
3. An area of low pressure associated with the remnants of Peter
located several hundred miles south of the coast of Newfoundland
is producing disorganized showers and thunderstorms. This system
is moving northeastward into a region of very strong upper-level
winds, and significant development is not anticipated. Additional
information on this system can be found in High Seas Forecasts
issued by the National Weather Service.
