Synopsis for the Gulf of Mexico .SYNOPSIS...A modest cold front will move S through the eastern Gulf Wed through Fri, followed by moderate to locally fresh N to NE winds E of 90W through Sat morning. Otherwise, weak high pressure will generally dominate the basin through the week, yielding light to gentle winds through tonight, and gentle to moderate thereafter. Seas are presently slight, but will build with the increasing winds behind the front. Popocatepetl Volcano in Mexico near 19N99W has been active and continues to erupt. Volcanic ash has moved E to ESE away from the volcano and over the Bay of Campeche to the Yucatan coast, S of 21N. Visibility may be restricted in this area due to volcanic ashfall through at least tonight. Mariners should exercise caution. If mariners encounter volcanic ash or floating volcanic debris, you are encouraged to report the observation to the National Weather Service by calling 305-229-4424.
