ASIDE FROM CONDITIONS ASSOCIATED WITH POLO, MODERATE TO WEAKER
WINDS DOMINATE. SEAS ARE 1 TO 3 FT IN THE GULF OF CALIFORNIA,
AND 4 TO 7 FT OVER THE REMAINDER OF THE WATERS AWAY FROM POLO.
CONVECTION HAS DEVELOPED IN THE SOUTHERN GULF OF CALIFORNIA IN
ASSOCIATION WITH A SURFACE TROUGH.
FOR THE FORECAST, MAJOR HURRICANE POLO WILL MOVE TO 15.4N 102.0W
THIS AFTERNOON, 16.2N 103.4W THU MORNING, 16.5N 105.0W THU
AFTERNOON, 16.7N 107.0W FRI MORNING, 16.9N 108.8W FRI AFTERNOON,
AND 17.3N 110.6W SAT MORNING. POLO WILL CHANGE LITTLE IN
INTENSITY AS IT MOVES TO 19.4N 112.7W EARLY SUN. LOOKING AHEAD,
ODALYS IS FORECAST TO SLIGHTLY STRENGTHEN AND GRADUALLY APPROACH
THE WATERS JUST BEYOND THE BAJA CALIFORNIA OFFSHORE WATERS BY
THE END OF THE UPCOMING WEEKEND. OUTER SWELLS ASSOCIATED WITH
ODALYS WILL PROPAGATE INTO THE BAJA CALIFORNIA WATERS AND MIX
WITH THOSE FROM POLO TO CREATE VERY CONFUSED AND HAZARDOUS SEAS
THIS WEEKEND. FRESH TO STRONG NORTHERLY GAP WINDS MAY DEVELOP IN
THE GULF OF TEHUANTEPEC EARLY THU, THEN PULSE INTO THE UPCOMING
WEEKEND. LOOKING AHEAD, AN AREA OF LOW PRESSURE IS EXPECTED TO
FORM IN A COUPLE OF DAYS TO THE SOUTH OF THE GULF OF TEHUANTEPEC.
AFTERWARDS, ENVIRONMENTAL CONDITIONS SHOULD BE FAVORABLE FOR
GRADUAL DEVELOPMENT, AND A TROPICAL DEPRESSION IS LIKELY TO FORM
LATE THIS WEEK OR THIS WEEKEND AS THE SYSTEM MOVES SLOWLY WEST-
NORTHWESTWARD TO NORTHWESTWARD, PARALLEL TO THE COAST OF SOUTHERN
AND SOUTHWESTERN MEXICO.
