NWS National Hurricane Center Miami FL
200 AM EDT Tue Sep 19 2023

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

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane 
Nigel, located over the central subtropical Atlantic.

1. Eastern Tropical Atlantic:
A tropical wave is expected to move off the west coast of Africa by 
Wednesday.  Environmental conditions are forecast to be conducive 
for gradual development of the wave thereafter, and a tropical 
depression is likely to form late this week or this weekend while 
the system moves westward across the eastern and central tropical 
Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...high...70 percent.

2. Western Atlantic:
A non-tropical area of low pressure is forecast to form east of 
the Florida peninsula late this week.  This system could acquire 
some subtropical characteristics this weekend while it moves 
generally northward.  Regardless of subtropical development, this 
low could bring gusty winds, heavy rain, and high surf conditions to 
portions of the coastal Carolinas into the coastal Mid-Atlantic 
states this weekend.  Please see products from your local National 
Weather Service office for more details.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.
