Synopsis for the Gulf of America
1011 PM EDT Thu Jul 17 2025

.SYNOPSIS...An area of broad low pressure, AL93, moving westward along
the northern Gulf coast and is now centered over southeastern 
Louisiana. This system is forecast to move farther inland through 
Fri, and tropical development is not expected. Nonetheless, heavy
rainfall could still produce localized flash flooding over 
portions of the north-central Gulf Coast through Friday. Elsewhere,
moderate to fresh E to NE winds will prevail north of the Yucatan
Peninsula and into the eastern Bay of Campeche each afternoon and
evening into next week. High pressure building over the 
northeastern Gulf this weekend will support gentle to moderate 
winds and seas across the rest of the basin.
