Synopsis for the Gulf of Mexico

.SYNOPSIS...Disorganized showers and thunderstorms over the
south- central Gulf of Mexico are associated with a surface
trough and an upper-level disturbance. The system is expected to
move slowly northeastward over the central and northeastern Gulf
of Mexico during the next couple of days. Upper-level winds are
currently unfavorable for development, but they are forecast to
become marginally conducive for some limited development as the
system nears the northern Gulf coast on Wednesday and Wednesday
night. Aside from this low pressure, high pressure will bring
light to gentle winds and slight seas through Fri.
