Synopsis for the Gulf of Mexico

.SYNOPSIS...A weak low pressure of 1016 mb is located over the
NW Gulf near 27N96W. A cold front extends from the Florida Big
Bend across SE Louisiana to near 28N94W. A warm front continues
from this point to the low center. A trough also extends from
the low across the western Gulf to near 18.5N94W. The cold front
will sweep across the eastern and central Gulf waters today
while weakening across the SE Gulf on Mon. The low will drift N
through Mon night, then ENE across the north-central Gulf
through Thu night and the NE Gulf by Fri, dragging a new cold
front across the SW Gulf. The pressure gradient between the low
and high pressure building over the SE of United States will
support fresh to strong N-NE winds and building seas over the
northern Gulf today. Fresh to strong northerly winds are also
expected over the western Gulf behind the cold front. On Mon,
fresh to strong winds will persist N of the warm front over the
NW Gulf while mainly fresh northerly winds will prevail W of the
cold front. Similar marine conditions are expected on Tue.
