Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 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 650 miles east of Bermuda is producing disorganized showers 
and thunderstorms.  Environmental conditions are only forecast to be 
marginally conducive for development, but a tropical depression 
could still form over the weekend.  The system is expected to move 
slowly eastward during the next day or two, but a faster 
northeastward motion is forecast to begin on Sunday.   
* 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 continues to produce a large area of 
disorganized showers and thunderstorms.  Gradual development of this 
system is expected, 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 for another day 
or so and then turn northward over the weekend. 
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.
