Special Tropical Weather Outlook

830 AM EST Wed Dec 7 2022

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

Special Tropical Weather Outlook issued to discuss the potential for 
subtropical development over the central Atlantic.

1. Central Subtropical Atlantic:
A large non-tropical area of low pressure located over the central 
subtropical Atlantic about 900 miles northeast of the northern 
Leeward Islands continues to produce a large area of showers and 
thunderstorms. This activity has become somewhat better organized 
this morning, though frontal features remain attached to the low.  
Environmental conditions appear marginally conducive for development 
and a subtropical or tropical storm could form within the next day 
or so.  By Friday, the low will move northeastward over cooler 
waters and interact with a mid-latitude trough, limiting the chance 
for additional subtropical or tropical development of the system.  
Additional information on this low, including warnings, can be found 
in High Seas Forecasts issued by the National Weather Service.  The 
next Special Tropical Weather Outlook on this system will be issued 
by 9 PM EST Wednesday, or earlier, if necessary.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.
