Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front across the northern Gulf will stall and
weaken along 27N tonight. Intense thunderstorms ahead of the
front may result in higher winds and seas. Areas of smoke and
haze in the western Gulf may reduce visibilities. A stronger
cold front will move into the NW Gulf on Sat, with strong
northerly winds and building seas expected across the western
Gulf this weekend. Gale force winds are possible near the
central coast of Mexico Sat night. The front will stall from
central Florida to the Bay of Campeche Sun night through early
next week.
