OTHERWISE, A BROAD RIDGE EXTENDS FROM A 1028 MB HIGH NE OF THE
HAWAIIAN ISLANDS NEAR 34N147W SOUTHEASTWARD TO NEAR THE
REVILLAGIGEDO ISLANDS. BROAD LOW PRESSURE EXTENDS FROM SOUTHERN
CALIFORNIA SSE ACROSS THE EASTERN COAST OF BAJA CALIFORNIA NORTE.
THIS PATTERN IS SUPPORTING LIGHT TO GENTLE NW TO N WINDS W OF
110W INCLUDING OFFSHORE BAJA CALIFORNIA, WHERE SEAS ARE MAINLY
7-9 FT IN A MIX OF CONVERGING S-SW AND SHORTER PERIOD NW SWELL.
GENTLE NW WINDS ACROSS THE WATERS OF BAJA SUR TURN WESTERLY
AROUND THE COAST AT CABO SAN LUCAS RESULTING IN FRESH TO LOCALLY
STRONG WESTERLY WINDS WRAPPING AROUND THE SOUTHERN TIP OF BAJA
CALIFORNIA, WHILE A FEW AREAS OF MODERATE W GAP WINDS PREVAIL
INSIDE THE SOUTHERN GULF OF CALIFORNIA. MODERATE S TO SW WINDS
ARE IN THE NORTHERN GULF OF CALIFORNIA N OF 30N AND W OF 114W.
GENTLE TO MODERATE NW WINDS ARE FOUND FROM 15N TO 22N, THEN
BECOME FRESH TO STRONG FROM CABO CORRIENTES TO THE AREA
SURROUNDING BORIS. SEAS ARE 7-15 FT E OF 110W TO THE W AND S OF
BORIS, AND LARGE CROSS-EQUATORIAL SW SWELL CONTINUES TO MOVE INTO
THE AREA WATERS. IN THE GULF OF CALIFORNIA, SEAS ARE 2-3 FT N OF
30N, 1-3 FT ACROSS THE REMAINDER OF THE NORTHERN AND CENTRAL
GULF, AND 4-7 FT IN THE SOUTHERN GULF WITH SOUTHERLY SWELL MOVING
THROUGH THE ENTRANCE.
FOR THE FORECAST, TROPICAL STORM BORIS WILL MOVE INLAND AND WEAKEN
TO A TROPICAL DEPRESSION NEAR 16.6N 98.7W TUE MORNING, INLAND TO
17.5N 99.8W TUE EVENING, AND DISSIPATE WED MORNING. ELSEWHERE,
A BROAD SURFACE RIDGE WILL SUSTAIN GENTLE TO MODERATE NW WINDS
ACROSS THE BAJA NORTE WATERS THROUGH WED, AND ACROSS THE BAJA SUR
TO REVILLAGIGEDO ISLANDS THROUGH EARLY WED BEFORE WEAKENING.
MODERATE TO FRESH NW TO N WINDS AND MODERATE TO ROUGH SEAS WILL
PREVAIL ACROSS THE FAR OUTER WATERS OF BAJA NORTE FOR THE EARLY
PART OF THE WEEK. LARGE, CROSS EQUATORIAL S-SW SWELL WILL
CONTINUE TO IMPACT SOUTHERN AND SOUTHWESTERN MEXICO WATERS
THROUGH TUE NIGHT, AND THE BAJA CALIFORNIA WATERS THROUGH WED,
AND WILL GENERATE VERY LARGE AND POWERFUL COAST ALONG THE LOCAL
COASTS AND OFFSHORE REEFS. THIS SWELL WILL ALSO MERGE WITH
SHORTER PERIOD NW SWELL ACROSS THE BAJA WATERS. MARINE CONDITIONS
SHOULD SIGNIFICANTLY IMPROVE BY THE END OF THE WEEK AND INTO THE
UPCOMING WEEKEND, WITH TRANQUIL CONDITIONS ACROSS THE OFFSHORE
WATERS OF MEXICO.
