RECENT SCATTEROMETER SATELLITE PASS PROVIDE OBSERVATION OF MODERATE
TO FRESH NORTHERLY WINDS ACROSS THE GULF OF TEHUANTEPEC AND DOWNWIND
TO ABOUT 14N. SEAS IN THESE WATERS ARE 5 TO 7 FT. ELSEWHERE, HIGH
PRESSURE OF 1022 MB LOCATED 31N133W EXTENDS A RIDGE SOUTHEASTWARD
ACROSS THE OFFSHORE WATERS OF BAJA CALIFORNIA PRODUCING LIGHT TO
GENTLE WINDS. FRESH TO LOCALLY STRONG SOUTHERLY WINDS ARE OVER
THE NORTHERN GULF OF CALIFORNIA. MODERATE EASTERLY WINDS AND
MODERATE SEAS ARE OCCURRING WEST OF THE REVILLAGIGEDO ISLANDS AS
TROPICAL STORM NORBERT CONTINUES TO PULL AWAY. ELSEWHERE IN THE
MEXICAN OFFSHORE WATERS, MODERATE OR WEAKER WINDS AND SLIGHT TO
MODERATE SEAS PREVAIL.
FOR THE FORECAST, TROPICAL STORM NORBERT WILL MOVE TO 16.9N
127.2W SAT MORNING, STRENGTHEN TO A HURRICANE NEAR 17.3N 129.1W
SAT AFTERNOON, 17.7N 131.0W SUN MORNING, 18.1N 132.9W SUN
AFTERNOON, 18.3N 134.8W MON MORNING, AND WEAKEN TO A TROPICAL
STORM NEAR 18.4N 136.8W MON AFTERNOON. NORBERT WILL CHANGE LITTLE
IN INTENSITY AS IT MOVES TO NEAR 18.2N 141.2W TUE AFTERNOON.
AS T.S. NORBERT CONTINUES TO MOVE WESTWARD, A STRONGER RIDGE
WILL BUILD ACROSS THE OFFSHORE WATERS OF BAJA CALIFORNIA,
BRINGING MODERATE TO LOCALLY FRESH NW TO N WINDS SUN INTO EARLY
NEXT WEEK. WINDS WILL ALSO INCREASE TO FRESH SPEEDS ACROSS THE
NORTHERN GULF OF CALIFORNIA EARLY NEXT WEEK, LIKELY DUE TO THE
PRESSURE GRADIENT BETWEEN THE RIDGE AND THE MEANDERING TROUGH
THAT IS IN PLACE IN THAT AREA. OTHERWISE, FRESH TO STRONG N TO NE
GAP WINDS WILL PULSE AGAIN IN THE TEHUANTEPEC REGION EARLY NEXT
WEEK.
AWAY FROM THE IMPACTS OF T.S. NORBERT, MODERATE TO LOCALLY FRESH
SE WINDS AND ROUGH SEAS ARE FOUND SOUTH OF 04N AND WEST OF THE
GALAPAGOS ISLANDS TO ABOUT 130W. HIGH PRESSURE OF 1022 MB LOCATED
JUST NORTH OF AREA DOMINATES THE N WATERS, MAINLY N OF 20N AND W
OF 110W. UNDER THE INFLUENCE OF THIS SYSTEM, AND AWAY FROM
NORBERT, MAINLY MODERATE WINDS AND MODERATE SEAS PREVAIL, WITH
THE EXCEPTION OF LIGHT TO GENTLE WINDS N OF 21N AND E OF 118W TO
BAJA CALIFORNIA PENINSULA.
