Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
825 PM 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 950 miles northeast of the northern 
Leeward Islands is producing an extensive area of disorganized 
showers and thunderstorms.  Although this system may acquire some 
subtropical characteristics tonight and Thursday, it is unlikely to 
become completely detached from a frontal zone.  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 AM EST Thursday, 
or earlier, if necessary.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

High Seas Forecasts issued by the National Weather Service
