.SYNOPSIS...Hazardous marine conditions will prevail through at
least Monday afternoon/evening over the Gulf waters and Laguna
Madre in wake of the passage of a cold front this morning. A Gale
Warning is in effect through 06Z Monday over the Gulf waters, but
may need to be extended to 12Z Monday. A Small Craft Advisory is
in effect through 18Z Monday across the Laguna Madre, and a Small
Craft Advisory will likely be issued for the Gulf waters from 12Z
Monday through 18Z Monday due to the combination of winds around

Monday evening as the pressure gradient weakens, with generally
favorable marine conditions by Tuesday. Small Craft Exercise
Caution to Small Craft Advisory conditions return on Wednesday and
once again over the weekend.
