800 AM EDT Fri Aug 27 2021

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

The National Hurricane Center is issuing advisories on Tropical 
Storm Ida, located over the northwestern Caribbean Sea near the 
Cayman Islands. 

An elongated area of low pressure located over the central Atlantic 
about 600 miles east of Bermuda is producing showers and 
thunderstorms.  Environmental conditions are expected to be 
marginally conducive for development, however, a tropical 
depression could still form over the weekend.  The system is 
expected to drift eastward today and Saturday, then accelerate 
northeastward on Sunday toward the central-north Atlantic.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...60 percent.

A tropical wave located about midway between the Cabo Verde Islands 
and the Lesser Antilles is producing limited showers and 
thunderstorms.  Gradual development of this system is expected, 
however, and a tropical depression is likely to form during the 
next couple of days before it moves into an environment of stronger 
upper-level winds and slightly cooler waters.  The disturbance is 
forecast to move west-northwestward today, then turn northward 
Saturday. 
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.
