Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Tue Aug 24 2021

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

The Weather Prediction Center is issuing Public Advisories on 
Post-Tropical Cyclone Henri, located inland near southern New 
England.

1. A broad trough of low pressure is producing disorganized showers and 
thunderstorms over the east-central tropical Atlantic more than 1000 
miles west-northwest of the Cabo Verde Islands. Little development 
is expected during the next day or two due to marginally conducive 
ocean temperatures and strong upper-level winds. Afterwards, 
environmental conditions are expected to become more favorable for 
gradual development, and a tropical depression could form by the end 
of the week while the system moves northwestward to northward at 10 
to 15 mph over the central Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...50 percent.

2. A tropical wave over the eastern Caribbean Sea is expected to form a 
broad area of low pressure over the southwestern Caribbean Sea later 
this week.  Thereafter, environmental conditions are forecast to be 
favorable for gradual development, and a tropical depression could 
form by the end of the week while the system moves 
west-northwestward to northwestward over the northwestern Caribbean 
Sea. 
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...60 percent.

3. Another tropical wave over the far eastern tropical Atlantic located 
about 500 miles south-southwest of the Cabo Verde Islands is 
producing a concentrated area of showers and thunderstorms. This 
activity has become a bit better organized tonight, and some 
additional development is possible over the next several days while 
this system moves westward to west-northwestward at 10 to 15 mph 
over the eastern tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...40 percent.
