Synopsis for the Gulf of Mexico

.SYNOPSIS...A strong cold front from the north central Gulf to
the central Bay of Campeche will move eastward, pushing east of
the basin by the end of the weekend. An intense area of
thunderstorms with locally higher winds and seas will precede
the front. Strong to gale-force NW winds are expected
immediately behind the front through around sunset. Hazy
conditions generated by agricultural fires in Mexico will linger
across the central Gulf and eastern Bay of Campeche ahead of the
front. High pres will become centered over the eastern Gulf Mon
through Wed. Popocatepetl Volcano in Mexico at 19.1N 98.4W is
currently in a state of unrest and is producing volcanic ash
extending into portions of the SW Gulf of Mexico. Volcanic ash
may be reaching the surface S of 21N W of 94W. Mariners should
exercise caution. If mariners encounter volcanic ash or floating
volcanic debris, you are encouraged to report the observation to
the National Hurricane Center by calling 305-229-4424.
