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

The National Hurricane Center is issuing advisories on Tropical 
Storm Bill, located a few hundred miles south-southeast of Halifax, 
Canada.

1. Disorganized showers and thunderstorms continue over the Bay 
of Campeche and southern Mexico in association with a broad 
low pressure area. This system is expected to move little during 
the next day or two, and any development should be slow to occur 
during that time period due to its close proximity to land.  
However, the disturbance should begin to move northward by 
Thursday, and a tropical depression is likely to form late in 
the week when the low moves across the central and 
northwestern Gulf of Mexico. Regardless of development, 
heavy rainfall will continue over portions of Central America 
and southern Mexico during the next several days. Heavy rains 
could also begin to impact portions of the northern Gulf Coast 
on Friday. Please consult products from your local 
meteorological service for more information.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...80 percent.

2. Shower activity is limited in association with a tropical 
wave located a few hundred miles south-southwest of the Cabo Verde 
Islands. Development, if any, should be slow to occur during the 
next couple of days while the wave moves westward. Thereafter, a 
combination of dry air aloft and strong upper-level winds should 
end the chances of formation when the wave reaches the central 
tropical Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
