NORTHERN GULF OF CALIFORNIA GALE WARNING:
A STRONG RIDGE OF HIGH PRESSURE JUST WEST OF THE BAJA CALIFORNIA
PENINSULA IS GOING TO INDUCE A GALE WIND EVENT IN THE NORTHERN
AND CENTRAL GULF OF CALIFORNIA THIS EVENING THROUGH EARLY MON
MORNING. THESE WINDS WILL STAY AT FRESH TO STRONG THROUGH SUN BUT
WILL PEAK AT NEAR-GALE TO GALE-FORCE AT THE NORTHERN GULF OF
CALIFORNIA ON SUN NIGHT, ALONG WITH SEAS NEAR 9 FT. AS THE RIDGE
WEAKENS ON MON, BOTH WINDS AND SEAS SHOULD QUICKLY SUBSIDE
THROUGH MON AFTERNOON.
THE PRESSURE GRADIENT BETWEEN A STRONG, BROAD SURFACE RIDGE WEST
OF BAJA CALIFORNIA AND A THERMAL TROUGH OVER BAJA CALIFORNIA IS
GENERALLY MODERATE TO FRESH NW WINDS WITH 8 TO 11 FT SEAS IN
LARGE NW SWELL NEAR BAJA NORTE, AND MODERATE NW TO N WINDS WITH 6
TO 7 FT SEAS IN MODERATE NW SWELL NEAR BAJA SUR. GENTLE TO
MODERATE N WINDS AND SEAS NEAR 6 FT ARE PRESENT NEAR THE
REVILLAGIGEDO ISLANDS. GENTLE TO MODERATE SE TO S WINDS AND SEAS
AT 2 TO 4 FT EXIST AT THE NORTHERN GULF OF CALIFORNIA, WHILE
LIGHT TO GENTLE WINDS AND 1 TO 2 FT SEAS EXIST FOR THE REST OF
THE GULF. LIGHT TO GENTLE WINDS ALONG WITH 2 TO 5 FT SEAS IN
MIXED MODERATE SWELLS PREVAIL FOR THE OFFSHORE WATERS OF CENTRAL
AND SOUTHERN MEXICO.
FOR THE FORECAST, STRONG RIDGE OF HIGH PRESSURE TO THE WEST WILL
CAUSE FRESH TO STRONG S TO SW GAP WINDS IN THE NORTHERN AND
CENTRAL GULF OF CALIFORNIA THIS EVENING THROUGH EARLY MON
MORNING. THESE WINDS WILL PEAK AT NEAR-GALE TO GALE-FORCE IN THE
NORTHERN GULF OF CALIFORNIA ALONG WITH ROUGH SEAS SUN NIGHT. IN
ADDITION, NW WINDS AT FRESH TO STRONG OFF BAJA NORTE, AND AT
MODERATE TO FRESH OFF BAJA SUR ARE ANTICIPATED LATER TONIGHT
THROUGH MON MORNING. RAPIDLY BUILDING LONG-PERIOD NW SWELL IS
GOING TO CREATE ROUGH TO VERY ROUGH SEAS OFF BAJA NORTE THROUGH
TUE NIGHT, AND OFF BAJA SUR SUN THROUGH TUE.
FOR THE FORECAST, THE AFOREMENTIONED SURFACE RIDGE WILL STAY NEAR
IT CURRENT LOCATION THROUGH SUN, MAINTAINING TIGHT PRESSURE
GRADIENT OVER THE WATERS NORTH OF 27N BETWEEN 120W AND 130W. THIS
WILL KEEP FRESH TO STRONG NW TO N WINDS FOR THIS AREA THROUGH MON
MORNING. ASSOCIATED LONG-PERIOD, LARGE NORTHERLY SWELL WILL CONTINUE
TO RAISE SEAS ACROSS THE WATERS WEST OF BAJA CALIFORNIA NORTE TO
NEAR 130W, REACHING 11 TO 17 FT SUN AND SUN NIGHT, AND FROM 9 TO
14 FT FROM PUNTA EUGENIA TO CABO SAN LAZARO. A TROUGH, WITH
POSSIBLE WEAK LOW PRESSURE ALONG IT, SHOULD DEVELOP OFFSHORE
SOUTHERN CALIFORNIA AND EXTREME NORTHERN BAJA CALIFORNIA EARLY
NEXT WEEK, WHICH WILL BREAK DOWN THE DESCRIBED TIGHT PRESSURE
GRADIENT, THUS ALLOWING FOR THE FRESH TO STRONG WINDS OVER THE
NORTHEAST PART OF THE AREA TO DROP-OFF QUITE SIGNIFICANTLY. THE
SWELL WILL GRADUALLY DECAY GOING INTO THE MIDDLE PART OF NEXT
WEEK, WITH SEAS LOWERING TO JUST BELOW 8 FT.
