1. A large area of low pressure located over the central subtropical
Atlantic about 750 miles northeast of the northern Leeward Islands
is producing disorganized showers and thunderstorms.  Environmental
conditions appear conducive for this system to acquire some
subtropical characteristics while it drifts northeastward during the
next few days.  By Thursday night or Friday, however, the low is
expected to move over cooler waters, ending its chances of becoming
a subtropical cyclone.  Additional information on this system,
including gale 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 today or
earlier.
* Formation chance through 48 hours...low...30 percent.

* Formation chance through 5 days...medium...40 percent.

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
830 PM EST Mon Dec 5 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 and complex 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 disorganized
showers and thunderstorms.  Environmental conditions appear
conducive for this system to acquire some subtropical or tropical
characteristics while it meanders generally northeastward during the
next few days.  By Friday, the low is expected to move over cooler
waters and interact with a mid-latitude trough, limiting potential
of tropical transition after that time.  Additional information on
this system, including gale 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
Tuesday, or earlier, if necessary.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.
