NWS NATIONAL HURRICANE CENTER MIAMI, FL
424 PM 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
A COLD FRONT HAS MOVED INTO THE NW GULF TODAY AND
EXTENDS FROM CENTRAL LOUISIANA TO ALONG THE TEXAS-MEXICO BORDER.
NORTHERLY WINDS BEHIND THE FRONT WILL GRADUALLY INCREASE
TONIGHT, BECOMING STRONG BY EARLY SUN AS THE FRONT REACHES FROM
THE FLORIDA BIG BEND TO NEAR VERACRUZ, MEXICO. STRONG HIGH
PRESSURE OVER THE CENTRAL U.S. WILL BUILD ACROSS THE BASIN
BEHIND THE PROGRESSING FRONT ON SUN TO PRODUCE A BRIEF PERIOD OF
GALE FORCE WINDS SUN AFTERNOON IN THE WESTERN GULF WATERS
OFFSHORE OF TAMPICO AND VERACRUZ. THE FRONT IS EXPECTED TO STALL
ACROSS THE YUCATAN CHANNEL AND STRAITS OF FLORIDA ON MON AND
GRADUALLY DISSIPATE THROUGH TUE. LOW PRESSURE IS EXPECTED TO
FORM OVER THE NW GULF ON MON NIGHT, THEN TRACK SOUTHEASTWARD
THROUGH WED, DRAGGING A STRONG COLD FRONT ACROSS THE ENTIRE
BASIN. STRONG HIGH PRESSURE BEHIND THE FRONT WILL INDUCE GALE
FORCE N TO NE WINDS EXPANDING ACROSS MUCH OF THE NORTHERN AND
WESTERN GULF TUE AND TUE NIGHT, WITH THE POTENTIAL FOR GUSTS TO
STORM FORCE ACROSS CENTRAL PORTIONS. MARINERS ARE URGED TO
EXERCISE EXTREME CAUTION ACROSS THE BASIN, DUE TO THE EXPANSIVE
AREA OF GALE FORCE WINDS AND LARGE AREA OF SEAS 15 TO 20 FT
EXPECTED TO ACCOMPANY THIS NEXT FRONTAL SYSTEM.
