Synopsis for the Gulf of Mexico

.SYNOPSIS...Showers and thunderstorms have increased today over
the south-central Gulf of Mexico in association 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 more conducive for some limited tropical or subtropical
cyclone development as the system nears the northern Gulf coast
on Wednesday and Wednesday night. Aside from this low pressure,
high pressure will continue to bring light to gentle winds and
slight seas through Fri. Winds and seas could be higher near
thunderstorms.
