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.
1. 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.
