Synopsis for the Gulf of Mexico
332 PM EDT Thu Apr 15 2021

.SYNOPSIS...A cold front across the northern Gulf will stall and
weaken along 27N tonight. Intense thunderstorms ahead of the front
may result in higher winds and seas. Areas of smoke and haze in
the western Gulf may reduce visibilities. A stronger cold front
will move into the NW Gulf on Sat, with strong northerly winds and
building seas expected across the western Gulf this weekend. Gale
force winds are possible near the central coast of Mexico Sat
night. The front will stall from central Florida to the Bay of
Campeche Sun night through early next week.
