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

The Weather Prediction Center is issuing advisories on Tropical 
Depression Nicholas, located near the Texas/Louisiana border. 

1. Showers and thunderstorms associated with a low pressure area 
located a few hundred miles south-southwest of the Cabo Verde 
Islands continue to show signs of organization.  Environmental 
conditions are expected to remain conducive for development, and a 
tropical depression is likely to form within the next couple of 
days.  This system is expected to move westward to 
west-northwestward across the tropical Atlantic during the next 
several days.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

2. A broad area of low pressure located a few hundred miles northeast 
of the central Bahamas is producing a large area of disorganized 
showers and thunderstorms.  Environmental conditions appear 
marginally conducive for development, and a tropical depression is 
likely to form during the next couple of days while the system moves 
north-northwestward to northward off the southeast U.S. coast. 
Regardless of development, this system could bring high surf to 
portions of the southeast and mid-Atlantic U.S. coasts later this 
week.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.

3. A tropical wave is expected to emerge off the west coast of 
Africa in a day or two. Thereafter, environmental conditions are 
forecast to be conducive for development while the system moves 
generally west-northwestward to northwestward over the 
far eastern Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
