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.



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.



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.
