Southeast 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.  

.TODAY...NE winds 15 to 20 kt. Seas 2 ft or less, building to
3 to 4 ft. 
.TONIGHT...NE to E winds 15 to 20 kt. Seas 3 to 5 ft. 
.MON...E winds 15 to 20 kt. Seas 3 to 5 ft.

.WED NIGHT...NE winds 5 to 10 kt. Seas 2 ft or less. 
.THU...NE to E winds 5 to 10 kt. Seas 2 ft or less. 
.THU NIGHT...N winds 5 to 10 kt. Seas 2 ft or less.  

Within 200 nm east of the coast of Florida

.SYNOPSIS...A strong cold front currently moving off NE Florida 
will reach from near Bermuda to south Florida tonight, and from 
28N65W to the Florida Keys by Mon evening, then become
stationary. Fresh to strong winds and building seas are expected
behind this  front through late Mon as strong high pressures
slides eastward  off the U.S. east coast. The high pressure and
front will weaken  Tue through early Thu allowing for winds to
diminish and seas to  subside. On Thu, the pressure gradient is
forecast to tighten E of NE Florida between high pressure to the
N across the eastern  seaboard and a possible low pressure
developing N of the NW Bahamas.

.TODAY...N to NE winds 10 to 15 kt S of 27N, and N 15 to 20 kt N
of 27N. Seas 2 ft or less S of 27N, and 4 to 6 ft N of 27N. 
.TONIGHT...NE winds 15 to 20 kt. S of 27N, seas 2 ft or less,
building to 3 to 5 ft late. N of 27N, seas 5 to 7 ft. 
.MON...NE to E winds 15 to 20 kt. Seas 3 to 5 ft S of 27N, and
5 to 7 ft N of 27N. 
.MON NIGHT...E winds 15 to 20 kt. Seas 3 to 4 ft S of 27N, and
5 to 7 ft N of 27N. 
.TUE...E winds 10 to 15 kt. S of 27N, seas 3 ft in the morning,
subsiding to 2 ft or less. N of 27N, seas 4 to 6 ft.
