Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
845 AM EST Tue Dec 6 2022

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

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

1. Central Subtropical Atlantic:
A large area of low pressure located over the central subtropical 
Atlantic about 800 miles northeast of the northern Leeward Islands 
continues to produce a broad area of showers and thunderstorms.  
Environmental conditions appear marginally conducive for development 
and a subtropical or tropical storm could form in the next couple of 
days. By Thursday night or Friday, the low will move northeastward 
over cooler waters and interact with a mid-latitude trough, limiting 
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 tonight, or earlier, if necessary.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.
