Marine Weather HF Voice Broadcast for the Gulf of Mexico

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 for the Gulf of Mexico

.SYNOPSIS...Fresh to strong southeast winds along with
occasionally rough seas will prevail from the south-central Gulf
to the northwest Gulf into Sun between high pressure over the
western Atlantic and broad low pressure over southern Mexico and
northern Central America. Winds and seas will diminish Sun into
Mon as the low pressure weakens, except for pulses off fresh to
strong winds off the north coast of the Yucatan Peninsula,
mainly at night. Looking ahead, a ridge will build from westward
from the western Atlantic across the northern Gulf through
mid-week. The associated gradient between the ridge and low
pressure with a cold front west of the area will support fresh
southeast return flow over the western Gulf through late Wed.
The cold front is expected to move into the western Gulf on Thu
followed by gentle to moderate north to northeast winds.

A large area of numerous thunderstorms, with strong to 
occasional gale-force wind gusts along with frequent lightning 
is over the NE Gulf. This activity is likely to continue through 
late tonight, while it gradually shifts to the southwest. 
Otherwise, hazy conditions persist over some areas of the 
western Gulf due to agricultural fires in southern Mexico.
