For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

A gale-force, non-tropical low pressure system is centered between
the Madeira Islands and the Azores. This system has become less
organized during the past 24 hours, and environmental conditions are
expected to become less conducive for development as the system
moves southwestward during the next day or two. Although
subtropical development is now unlikely, this system will continue
to produce strong winds and locally heavy rains in the Madeira
Islands and the Azores through Wednesday. Additional information on
this system can be found in High Seas Forecasts issued by Meteo
France.

This will be the last Special Tropical Weather Outlook issued on
this system. Regularly scheduled Tropical Weather Outlooks will
resume on June 1, 2021, 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.
