Synopsis for the Gulf of Mexico
400 AM EDT Tue May 21 2019

.SYNOPSIS...Strong SE to S winds and building seas are expected 
across the western Gulf between high pressure over the southeast 
U.S. and lower pressure over the Central Plains. Fresh to strong 
easterly winds near the west coast of Yucatan Peninsula are 
possible each night as a trough moves W from land. Smoke and haze
from fires across southern Mexico will reduce visibilities over 
the western Gulf and the Bay of Campeche the next several days.
