Synopsis for the Gulf of Mexico

.SYNOPSIS...Showers and thunderstorms over the Bay of Campeche
and southern Gulf of Mexico have been increasing during the past
several hours near and east of a surface trough of low pressure.
A tropical depression is expected to form later today or tonight
while the system moves northwestward and then northward near the
coast of northeastern Mexico. Additional development is possible
through the middle of next week if the system remains over
water, and interests along the western and northwestern Gulf
coast should monitor the progress of this disturbance.
Regardless of development, by late today, heavy rain is expected
to reach portions of the Texas and Louisiana coasts and continue
across those coasts through the middle of the week. Meanwhile,
quiescent conditions are expected to prevail across the central
and eastern Gulf through midweek.
