Atlantic Tropical Weather Outlook

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
230 AM EST Thu Dec 8 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.

Central Subtropical Atlantic:
Showers and thunderstorms have increased since last evening near a 
large non-tropical area of low pressure located over the central 
subtropical Atlantic about 850 miles east-southeast of Bermuda.  
However, the system remains embedded within a frontal zone, which is 
expected to become more pronounced later today as the low begins to 
move east-northeastward at 20 to 25 mph toward colder waters and 
interact with a mid-latitude trough.  Therefore, while the system 
could show some subtropical characteristics today, its chances to 
fully transition to a subtropical or tropical cyclone appear to be 
decreasing.  Nevertheless, significant non-tropical development of 
this low is expected during the next couple of days, and additional 
information, including hurricane-force wind 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.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
