Synopsis for the Gulf of Mexico

.SYNOPSIS...A weak cold front will move S into and dissipate
over the far northern Gulf of Mexico through Tue, 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 N to NE winds to the basin. Popocatepetl Volcano in
Mexico near 19N99W has had several large eruptions in the past
day and eruptions continue this morning. Ash has moved E-NE away
from the volcano and over portions of the SW Gulf of Mexico, S
of 22N and W of 91W. Visibility may be restricted in this area
due to volcanic ashfall through this afternoon. Mariners should
exercise caution.
