Synopsis for the Gulf of Mexico

.SYNOPSIS...A ridge will continue to dominate the Gulf waters
the remainder of the week. The pressure gradient between the
ridge and a deepening low pressure across the Southern Plains
and northern Mexico will result in an increase in winds and seas
across the Gulf region later today through Fri. Under this
weather pattern, expect fresh to strong E to SE winds, and
building seas of up to 10 or 11 ft Thu and Fri. Similar marine
conditions are expected in the Straits of Florida.
