Synopsis for the Gulf of Mexico
401 PM EDT Sun May 19 2024

.SYNOPSIS...A weak frontal trough extends from near Fort Myers,
Florida southwestward to 25N85W and to near 22N96W. Scattered 
showers and thunderstorms are along the trough east of 89W and
south from the trough to 25N. Similar activity is from 22N to 25N
between 87W and 92W. This activity is being supported by a rather
vigorous mid to upper-level trough that extends from the southeastern
U.S. coast southwestward to the south-central Gulf. The trough 
and associated weather will continue to shift E to SE across the 
eastern Gulf, reaching the vicinity of the Florida Keys Mon night 
and the Straits of Florida Tue. Winds are likely to be gusty along
with rough seas in and near the shower and thunderstorm activity.
Meanwhile, hazy conditions due to agricultural fires in Mexico 
continue across most of the western Gulf and Bay of Campeche. 
Moderate to locally fresh SE return flow will develop again across
the W Gulf Tue through Fri night.
