NORTHWEST WINDS ARE OFFSHORE BAJA CALIFORNIA WHILE MODERATE OR
WEAKER WINDS ACROSS THE REMAINDER OF THE WATERS. SEAS ARE 1 TO 3
FT IN THE GULF OF CALIFORNIA, AND 4 TO 7 FT OVER THE REMAINDER

TROPICAL STORM ODALYS IS CENTERED NEAR 15.1N 130.1W, OR ABOUT

THAT ITS DEEP CONVECTION OF NUMEROUS STRONG TYPE INTENSITY
IS WITHIN 180 NM OF THE CENTER IN THE NE QUADRANT, 270 NM OF

THE CENTER IN THE SW QUADRANT AND 90 NM OF THE CENTER IN THE NW
QUADRANT. ODALYS IS FORECAST TO MAINTAIN ITS PRESENT MOTION OVER THE
NEXT COUPLE OF DAYS, FOLLOWED BY A GRADUAL TURN TO THE NORTHEAST
LATE THIS WEEK. ADDITIONAL STRENGTHENING IS FORECAST, AND ODALYS
COULD BECOME A HURRICANE LATER TODAY OR TONIGHT.
FOR THE FORECAST, MAJOR HURRICANE POLO WILL MOVE TO NEAR 15.0N
101.8W LATE TONIGHT WITH MAXIMUM SUSTAINED WINDS 160 KT GUSTS 195
KT, TO NEAR 15.5N 102.4W WED AFTERNOON, TO NEAR 16.2N 103.6W LATE
WED NIGHT WITH MAXIMUM SUSTAINED WINDS 155 KT GUSTS 190 KT, TO NEAR
16.7N 105.2W THU AFTERNOON WITH MAXIMUM SUSTAINED WINDS 150 KT GUSTS
185 KT, TO NEAR 17.0N 106.9W LATE THU NIGHT WITH MAXIMUM SUSTAINED
WINDS 130 KT GUSTS 160 KT, TO NEAR 17.4N 108.5W FRI AFTERNOON AND TO
NEAR 18.7N 111.5W SAT AFTERNOON WITH MAXIMUM SUSTAINED WINDS 115 KT

WILL PREVAIL ACROSS THE OFFSHORE BAJA CALIFORNIA WATERS THROUGH
EARLY FRI MORNING WHEN CONDITIONS IN BAJA CALIFORNIA SUR OFFSHORES
WILL START TO DETERIORATE DUE TO THE PROXIMITY OF POLO. LOOKING
AHEAD, TROPICAL STORM ODALYS CURRENTLY WELL TO THE SOUTHWEST OF THE
SOUTHERN TIP OF BAJA CALIFORNIA IS FORECAST TO STRENGTHEN TO A
HURRICANE 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. ALSO, AN AREA OF LOW PRESSURE IS
EXPECTED TO FORM IN THE NEXT FEW DAYS TO THE SOUTH OF THE GULF OF
TEHUANTEPEC. AFTERWARDS, ENVIRONMENTAL CONDITIONS SHOULD BE
FAVORABLE FOR GRADUAL DEVELOPMENT, AND A TROPICAL DEPRESSION COULD
FORM LATE THIS WEEK OR THIS WEEKEND AS THE SYSTEM MOVES SLOWLY WEST-
NORTHWESTWARD TO NORTHWESTWARD. THIS MOTION SHOULD KEEP IT PARALLEL
TO THE COAST OF SOUTHERN AND SOUTHWESTERN MEXICO.
