200 PM EDT Wed Sep 15 2021

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 have changed little in organization in 
association with an area of low pressure located a few hundred 
miles southwest of the Cabo Verde Islands.  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. Satellite images indicate that a low pressure system located a few 
hundred miles northeast of the central Bahamas is gradually becoming 
better defined.  However, the associated showers and thunderstorms 
are still disorganized.  Environmental conditions are expected to 
become more conducive for development, and a tropical depression is 
likely to form during the next day or two 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.  The Air Force Hurricane Hunters are currently enroute to 
investigate the disturbance.
* Formation chance through 48 hours...high...70 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.
