Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Thu Sep 21 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 currently located near the Cabo Verde Islands.
This system is expected to merge with another disturbance located a
few hundred miles to its west in a few days.  Environmental
conditions are forecast to be conducive for gradual development, and
a tropical depression is likely to form late this week or this
weekend while the system moves generally westward at 10 to 15 mph
across the eastern and central tropical Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...high...70 percent.

Western Atlantic:
A non-tropical low pressure system is expected to form within a
large area of disorganized showers and thunderstorms to the east
of the Florida peninsula within the next day or so.  This system
could acquire some subtropical characteristics on Friday while it
moves generally northward.  Regardless of development, this low is
likely to bring gusty winds to gale force, heavy rain, and high surf
to portions of the Southeast and Mid-Atlantic United States late
this week and into this weekend.  Additional information on this
system can be found in High Seas Forecasts and products from your
local National Weather Service office.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...40 percent.
