 Synopsis for the Gulf of America
 318 PM EDT Thu Jun 18 2026
 
 
 .SYNOPSIS...The Atlantic ridge extends across Florida into the
 Gulf region. The pressure gradient between this system and lower
 pressures over Texas and northeastern Mexico will support fresh
 to strong southerly winds over the western and central Gulf, and
 moderate to fresh winds over the eastern Gulf through Fri.
 Expect rough seas N of 27N and offshore of the Louisiana coast
 this afternoon to shift eastward with these winds through tonight
 before diminishing. Winds and seas will diminish basin-wide late
 Fri through the weekend as weak high pressure settles over the
 eastern Gulf.
