Special Tropical Weather Outlook

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 non-tropical low pressure area located about 925 miles 
east-southeast of Bermuda continues to produce an extensive area
of showers and thunderstorms.  However, the system remains 
embedded within a frontal zone, which is expected to become even 
more pronounced later today as the low begins to move 
east-northeastward at 20 to 25 mph toward colder waters and 
interacts with a mid-latitude trough.  Therefore, it is unlikely 
that the low will transition to a subtropical or tropical cyclone. 
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.

This will be the last Special Tropical Weather Outlook issued on 
this system.  Regularly scheduled Tropical Weather Outlooks will 
resume on May 15, 2023, while Special Tropical Weather Outlooks 
will be issued as necessary during the off-season. 
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

High Seas Forecasts issued by the National Weather Service can be 
found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and
