Synopsis for the Gulf of Mexico

.SYNOPSIS...Fresh to strong southeast winds and building over
the western Gulf will continue through tonight as low pressure
deepens over southwestern Texas. The associated cold front will
move to just offshore the Texas coast Thu evening, and slowly
move across the NW Gulf through Fri. It will reach from west-
central Florida to the central Gulf and to the Bay of Campeche
by early Sat and become stationary. The front will lift back to
the north as a warm front through Sun, except over the western
Gulf it will weaken and dissipate by late Sun. Fresh to strong
northerly winds surge southward behind the front W of 96W and S
of 25N Fri and Fri night. The high pressure will remain in place
Mon and Mon night. Southerly flow will increase over the far
western Gulf Sun through Mon night. Areas of smoke over the SW
Gulf are due to agricultural fires in southern Mexico. These
conditions are expected to continue through at least the end of
the week, while hazy conditions will remain over the
west-central Gulf and eastern Bay of Campeche. Visibility may be
reduced in the SW Gulf, especially near the coast.
