Synopsis for the Gulf of Mexico

.SYNOPSIS...A strong cold front exited the area this afternoon.
In its wake, strong to minimal gale force northerly winds and
large seas are present across much of the Gulf...including the
vicinity of the Yucatan Channel. These conditions will slowly
subside through Thu over the central and western sections of the
Gulf. Strong northeast to east winds will continue in the
Straits of Florida, after the frontal passage, through Fri. A
low pressure center is expected to develop in the N central Gulf
on Friday night, and move across northern Florida during the
weekend. Gale-force winds are possible in the NE Gulf with the
low pressure center.
