MARINE WEATHER HF VOICE BROADCAST FOR THE GULF OF MEXICO
SEAS GIVEN AS SIGNIFICANT WAVE HEIGHT, WHICH IS THE AVERAGE
HEIGHT OF THE HIGHEST 1/3 OF THE WAVES. INDIVIDUAL WAVES MAY BE
MORE THAN TWICE THE SIGNIFICANT WAVE HEIGHT.
SYNOPSIS
FRESH SOUTHWEST WINDS OVER THE NORTHERN AND WESTERN
GULF WILL CONTINUE THROUGH SAT AS A WARM FRONT LIFTS NORTHWARD
AHEAD OF DEVELOPING LOW PRESSURE IN THE SOUTH-CENTRAL UNITED
STATES. A RATHER SHARP COLD FRONT ASSOCIATED WITH THE
AFOREMENTIONED LOW IS EXPECTED TO ENTER THE NW GULF SAT MORNING,
FOLLOWED BY FRESH NORTHWEST TO NORTH WINDS WILL INITIALLY FOLLOW
THE FRONT. THESE WINDS ARE FORECAST TO INCREASE TO STRONG SPEEDS
BY EARLY SUN AS THE PRESSURE GRADIENT TIGHTENS BETWEEN THE FRONT
AND BUILDING STRONG HIGH PRESSURE OVER THE CENTRAL U.S. NEAR-
GALE FORCE WINDS WILL BE POSSIBLE ON SUN OVER THE SOUTHWESTERN
GULF OFFSHORE OF TAMPICO AND OFFSHORE VERACRUZ. ROUGH SEAS ARE
EXPECTED TO ACCOMPANY THE WINDS. LOOKING AHEAD, LOW PRESSURE IS
EXPECTED TO FORM OVER THE NW GULF EARLY NEXT WEEK, WITH AN
ATTENDANT POTENT COLD FRONT. THE LOW WILL TRACK EASTWARD THROUGH
MID-WEEK DRAGGING THE COLD FRONT ACROSS THE ENTIRE BASIN. NEAR
GALE TO GALE FORCE NORTH TO NORTHEAST WINDS ARE EXPECTED TO MOVE
INTO MOST OF THE NORTHERN AND WESTERN GULF EARLY NEXT WEEK.
ROUGH TO VERY ROUGH SEAS ARE EXPECTED WITH THESE WINDS. MARINERS
ARE URGED TO EXERCISE CAUTION ACROSS THE BASIN, INCLUDING
OUTSIDE OF THE GALE CONDITION AFFECTED ZONES, DUE TO THE
EXPANSIVE AREA OF STRONG TO NEAR-GALE FORCE WINDS AND ROUGH SEAS
ASSOCIATED WITH SUCCESSIVE FRONTAL SYSTEMS.
