NWS NATIONAL HURRICANE CENTER MIAMI, FL
227 AM EST SAT JAN 18 2025
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 TODAY AHEAD OF DEEPENING LOW PRESSURE IN THE
SOUTH-CENTRAL UNITED STATES. A RATHER SHARP COLD FRONT
ASSOCIATED WITH THE AFOREMENTIONED LOW WILL ENTER THE NW GULF
LATE THIS MORNING, FOLLOWED INTIALLY BY FRESH NORTHWEST TO NORTH
WINDS. 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 TO GALE-FORCE WINDS WILL BE POSSIBLE SUN AND SUN NIGHT IN
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.
