NWS National Hurricane Center Miami FL
730 PM EDT Mon May 21 2018

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

1. A broad surface low pressure area has formed over the northwestern
Caribbean Sea a couple of hundred miles east of the coast of Belize.
This low and an upper-level trough are producing widespread
cloudiness and showers extending from the northwestern Caribbean
Sea across Cuba and the Florida peninsula.  While environmental
conditions are expected to be unfavorable for development during
the next couple of days, some gradual subtropical or tropical
development is possible later this week while the system moves
slowly northward into the central or eastern Gulf of Mexico.
Regardless of development, locally heavy rainfall is possible
across western Cuba and much of Florida during the next several
days.  For more information on the heavy rain threat, please see
products issued by your local weather office. The next Special
Tropical Weather Outlook on this system will be issued by 800 AM
EDT on Tuesday.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.
