Synopsis for the Gulf of Mexico

.SYNOPSIS...Several weak cold fronts will move into and
dissipate over the far northern Gulf of Mexico early this week,
but overall weak high pressure will dominate. This pattern will
result in light to gentle winds and slight seas. A modest cold
front will move S through the eastern Gulf of Mexico Wed,
bringing gentle to moderate NE winds to the basin. Popocatepetl
Volcano in Mexico near 19N99W has had several large eruptions in
the past day and eruptions continue. Ash has moved ENE away from
the volcano and over portions of the SW Gulf of Mexico, S of 22N
and W of 93W. Visibility may be restricted in this area due to
volcanic ashfall through Mon morning. Mariners should exercise
caution.
