GMZ005 Synopsis For Keys Coastal Waters From Ocean Reef To Dry Tortugas 1031 Am Est Mon Dec 11 2023
Synopsis..A large area of high pressure across the eastern united states will maintain strong breezes tonight through at least Friday. Complicating the forecast for the next five days will be the return of the frontal boundary as a warm front, which will introduce the potential for locally heavy rainfall. Finally, there is also the potential for a period of near- gale breezes (28-33 knots) late this week as a winter low pressure system develops in the gulf of mexico.

New DISCUSSION, MARINE, AVIATION

DISCUSSION
Issued at 1032 AM EST Mon Dec 11 2023 Temperature are in the lower 70s across the Keys, with dewpoints below 60 for some communities, all thanks to an early morning FROPA. North winds peaked near 25 knots immediately after the front, but have since decreased to 20 knots or less at the Reef.
Highs this afternoon should only be a degree or two higher than current readings, and rain chances will be near nil. The typical clearing skies after a cold front may not be realized, with copious upper level cloud cover streaming northeast from the Yucatan. The inherited forecast remains on track and needs no adjustments.
