The monsoon trough resumes from 15N110W to 1011 mb low pressure centered near 15N113W to 10N125W to 10N140W.

For the Gulf of Tehuantepec...fresh to strong gap winds are expected to continue pulsing nightly through the end of this week with the assistance of nocturnal drainage flow. Looking ahead, strong high pressure will build southward into NE Mexico by mid week. This will cause winds to increase to minimal gale force during the overnight hours late Wednesday night through late Thursday night. For the Gulf of California...High pressure building across the U.S. Great Basin and Rocky Mountains will support fresh to strong northwest winds over the northern Gulf this evening through Wednesday morning, then again Wednesday night and Thursday morning. Elsewhere...Long period NW swell continues to propagate across the region, with combined seas of 8 to 10 ft over much of the region W of 100W. The swell will gradually decay below 8 ft through mid week, just ahead of another set of long period NW swell. Looking ahead, this next round of longer period swell will mix with shorter period waves emerging out of the Gulf of Tehuantepec by Thursday. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh gap winds in the Gulf of Papagayo will subside this morning, but resume on Thursday night. Elsewhere, light to gentle winds will prevail over the waters north of 10N, with moderate mainly SW winds S of 10N. Seas of 4 to 6 ft will persist across the region through the end of the week in mixed NW and S swell. REMAINDER OF THE AREA... A stalled front reaching from 30N135W to 25N140W will start to weaken later today then become diffuse Wednesday. 1021 mb high pressure centered near 32N124W will weaken as it shifts eastward ahead of the front. Fresh to strong SW winds ahead of the front are decreasing as the front weakens. Long period NW swell of 8 to 10 ft covering the area will decay below 8 ft by late tonight except for an area SW of Acapulco Mexico from 05N to 12N between 103W to 113W. However, another round of NW swell accompanying the stalled front is bringing combined seas of 8 to 20 ft to the NW corner of the discussion area W of a line from 30N130W to 22N140W. These swell will then gradually decay through the end of the week, only to be followed up by yet another bout of NW swell pushing into the area late Thursday through Friday. This set of swell will be associated with a new cold front that will weaken as it crosses 30N140W late Thursday night. $$ cam
