ITCZ/MONSOON TROUGH SECTION BELOW.
THE AXIS OF A TROPICAL WAVE IS NEAR 121W FROM 02N TO 18N, MOVING
WESTWARD AT 10 TO 15 KT. NEARBY CONVECTION IS DISCUSSED IN THE
ITCZ/MONSOON TROUGH SECTION BELOW.
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH
THE MONSOON TROUGH EXTENDS FROM 09N84W TO 09N104W. THE ITCZ

IS FROM 02N TO 08N EAST OF 125W.
..OFFSHORE WATERS WITHIN 250 NM OF MEXICO
FRESH TO STRONG WINDS PREVAIL OVER THE GULF OF TEHUANTEPEC.
GENTLE TO MODERATE WINDS ARE FOUND ELSEWHERE. MODERATE SEAS ARE
OVER THE OPEN WATERS OFF MEXICO, WITH SLIGHT TO MODERATE SEAS
OVER THE GULF OF CALIFORNIA.
FOR THE FORECAST, FRESH TO STRONG GAP WINDS ARE EXPECTED ACROSS
THE GULF OF TEHUANTEPEC THROUGH EARLY NEXT WEEK. THE PRESSURE
GRADIENT BETWEEN HIGH PRESSURE WEST OF THE AREA AND LOWER
PRESSURES OVER NORTHERN MEXICO WILL SUPPORT MODERATE TO LOCALLY
FRESH SOUTHERLY WINDS ACROSS THE NORTHERN GULF OF CALIFORNIA
TONIGHT INTO THU, THEN AGAIN ON THU NIGHT. A MODERATE PRESSURE
GRADIENT WILL PROMOTE MOSTLY GENTLE TO MODERATE WINDS ACROSS THE
REMAINDER OFFSHORE WATERS OF MEXICO ALONG WITH MODERATE SEAS.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
FRESH TO LOCALLY STRONG E GAP WINDS, AND MODERATE SEAS, PERSIST

FORMED TROPICAL DEPRESSION EIGHT-E AND ON POTENTIAL TROPICAL
CYCLONE ONE-E.
BROAD RIDGING DOMINATES THE WATERS NORTH OF 20N. OUTSIDE OF THE
AREA IMPACTED BY PTC ONE-C, THE PRESSURE GRADIENT BETWEEN THE
AREA OF HIGH PRESSURE AND EIGHT-E IS SUPPORTING FRESH TO LOCALLY
STRONG WINDS, AND ROUGH SEAS, FROM 15N TO 22N BETWEEN 130W AND
140W. ROUGH SEAS IN SOUTHERLY SWELL COVER THE WATERS S OF 05N
