Marine Weather HF Voice Broadcast for the Gulf of America

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

.SYNOPSIS...Weak high pressure has shifted into the N-central
Gulf overnight, and extends a narrow ridge southeastward to the
Yucatan Channel. The high pressure will drift slowly W-NW and
settle across the NW Gulf through Thu. A 1014 mb low pressure is
just offshore of central Florida near 29N79.5W and is forecast
to move westward across Florida later today and tonight, and
eventually emerge over the northeastern Gulf late Tue or early
Wed. Environmental conditions appear generally favorable for
additional development, and a tropical depression could form by
the middle to latter part of this week as this system moves
across the northeastern and north-central Gulf. Regardless,
scattered to numerous showers and thunderstorms, some with
strong gusty winds, will accompany this system.
