**SEA OF CORTEZ FORECAST**

A WEAK PRESSURE GRADIENT ACROSS THE REGION DUE TO THE PRESENCE OF
TROPICAL STORM MARIE TO THE WEST OF THE BAJA CALIFORNIA PENINSULA
IS SUPPORTING MAINLY GENTLE TO MODERATE NW WINDS OFF BAJA AND
LIGHT TO GENTLE WINDS ALONG WITH SLIGHT SEAS IN THE GULF OF
CALIFORNIA. A BROAD AREA OF LOW PRESSURE LOCATED SEVERAL HUNDRED
MILES SOUTHWEST OF SOUTHWESTERN MEXICO WITH POTENTIAL TO DEVELOP
INTO A TROPICAL CYCLONE LATER IN THE WEEK IS SUPPORTING MODERATE
TO FRESH WINDS OFF JALISCO AND SOUTH OF THE REVILLAGIGEDO
ISLANDS. OTHERWISE, MODERATE TO FRESH WINDS ARE PULSING IN
TEHUANTEPEC.
FOR THE FORECAST, MODERATE TO FRESH WINDS ARE EXPECTED TO
BRIEFLY DEVELOP OVER THE NEARSHORE WATERS OF BAJA CALIFORNIA AND
OVER SOME SECTIONS OF THE GULF OF CALIFORNIA TONIGHT INTO TUE AS
TROPICAL STORM MARIE, NEAR 25.1N 125.9W AT 8 PM PDT, MOVES
FARTHER AWAY FROM THE FORECAST WATERS. SHOWERS AND THUNDERSTORMS
ASSOCIATED WITH A BROAD AREA OF LOW PRESSURE LOCATED SEVERAL
HUNDRED MILES SOUTHWEST OF SOUTHWESTERN MEXICO REMAIN
DISORGANIZED. GRADUAL DEVELOPMENT OF THIS SYSTEM IS POSSIBLE, AND
A TROPICAL DEPRESSION COULD FORM LATER THIS WEEK WHILE THE
SYSTEM MOVES GENERALLY WEST- NORTHWESTWARD AT 10 TO 15 KT.
REGARDLESS OF DEVELOPMENT, THIS SYSTEM MAY BRING MODERATE TO
FRESH WINDS TO THE OFFSHORE WATERS OF JALISCO AND THE
REVILLAGIGEDO ISLANDS TONIGHT THROUGH WED NIGHT. OTHERWISE, THE
NEXT GAP WIND EVENT IN THE GULF OF TEHUANTEPEC IS EXPECTED TO
BEGIN TONIGHT AND PULSE TO STRONG SPEEDS THROUGH FRI.

TROPICAL STORM MARIE IS CENTERED NEAR 25.1N 125.9W AT 08/0300
UTC, MOVING WEST-NORTHWEST AT 7 KT. ESTIMATED MINIMUM CENTRAL
PRESSURE IS 994 MB. MAXIMUM SUSTAINED WIND SPEED IS 45 KT WITH
GUSTS TO 55 KT. PEAK SEAS HAVE LOWERED TO NEAR 17 FT. LATEST
SATELLITE IMAGERY CONTINUE TO SHOW A SHEARED MARIE, WITH ITS
CENTER HAVING BECOME EXPOSED TO THE NORTHWEST OF SCATTERED
MODERATE CONVECTION IN THE SE QUADRANT FROM 19N TO 25N BETWEEN
121W AND 126W. MARIE IS FORECAST TO TURN TO THE NORTHWEST
OVER THE NEXT COUPLE OF DAYS, AND IS FORECAST TO BECOME A POST-
TROPICAL REMNANT LOW BY WED. SWELLS GENERATED BY MARIE WILL
CONTINUE TO AFFECT PORTIONS OF THE COAST OF THE BAJA CALIFORNIA
PENINSULA AND SOUTHERN CALIFORNIA FOR THE NEXT COUPLE OF DAYS.
THESE SWELLS ARE LIKELY TO CAUSE LIFE-THREATENING SURF AND RIP
CURRENT CONDITIONS. PLEASE CONSULT PRODUCTS FROM YOUR LOCAL
WEATHER OFFICE.
