Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Mon Sep 4 2023

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

Active Systems:
The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Katia, located over the eastern subtropical
Atlantic.

Central Tropical Atlantic (AL95):
Showers and thunderstorms associated with an area of low pressure
located over the central tropical Atlantic about 800 miles
west-southwest of the Cabo Verde Islands have changed little in
organization through the day.  However, environmental conditions
are conducive for further development, and a tropical depression or
tropical storm is expected to form over the next day or so while the
low moves toward the west-northwest at 15 to 20 mph across the
central tropical Atlantic.  Additional strengthening, possibly to a
hurricane, is likely later this week while the system moves over
western portions of the tropical Atlantic, near or to the northeast
of the northern Leeward Islands.  For additional information on
this system, including gale warnings, see High Seas Forecasts issued
by the National Weather Service.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...near 100 percent.

Eastern Tropical Atlantic:
A strong tropical wave is forecast to move off the coast of West
Africa on Tuesday.  Environmental conditions appear conducive for
development once the wave moves offshore, and a tropical depression
could form over the far eastern tropical Atlantic during the middle
to latter part of the week while the system moves to the west or
west-northwest at 10 to 15 mph.  This system is expected to move
across the Cabo Verde Islands Wednesday night and Thursday, and
interests there should monitor its progress.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...60 percent.

Northeastern Atlantic (ex-Franklin):
Post-Tropical Cyclone Franklin is located several hundred miles
north of the Azores and is forecast to move quickly southeastward
towards warmer waters east of the Azores.  This system could acquire
some subtropical or tropical characteristics late this week or this
weekend while it moves erratically between the Azores and Portugal.
For additional information on this system, including gale warnings,
see High Seas Forecasts issued by Meteo France.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
