Synopsis for the Gulf of Mexico .SYNOPSIS...A front across the northern Gulf will slowly move S this afternoon 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 early afternoon, 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 remains in a state of unrest and continues to erupt and produce volcanic ash, however the current ash plume is confined from the coast of the Bay of Campeche inland and southward. Mariners should exercise caution in the southern Bay of Campeche. 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.
