000 AXPZ20 KNHC 060753 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 753 UTC Sun Nov 6 2016 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...SPECIAL FEATURES... A gale warning remains in effect for the Gulf of Tehuantepec through later this morning. High pressure north of the area will continue to support fresh to strong gap wind pulses mainly during overnight hours over the next couple of nights. Seas downstream of the stronger winds are up to 11 feet this morning, but will subside below 8 ft later today. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 09N90W to 12N102W to 10N110W to 10N118W. The ITCZ continues from 10N118W to 10N125W to 07N130W to 07N140W. Cluster of scattered moderate convection are from 04N to 09N between 76W and 86W. Scattered moderate isolated strong convection is from 08N to 14N between 92W and 122W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Other than the strong gap winds through the Gulf of Tehuantepec, generally light to moderate winds persist across the area under the influence of weak ridge extending from 1021 mb high pressure near 28N131W through to 20N110W. No significant change is expected through early next week. Lingering swell to 8 ft is present over much of the area between Socorro Island and Los Cabos, but this will decay below 8 ft through today. However, another set of long period 8 to 10 ft northwest swell is propagating into the waters of Baja California Norte this morning. This will reach as far south as the Revillagigedo Islands through late Monday before subsiding below 8 ft. Looking ahead, high pressure building north of the area over the southern Rockies will allow moderate to strong winds over the northern Gulf of California, with seas building to 5 ft. A third set of long period northwest swell will reach the offshore waters of Baja California Norte by mid week. Gap winds to near gale force are expected through the Gulf of Tehuantepec by Tuesday night into Wednesday morning. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to locally strong gap winds is likely early this morning in the Gulf of Papagayo. Otherwise, light to gentle winds will prevail over the waters north of 10N, with moderate to fresh winds south of 10N. Seas of 4-6 ft will persist across the region into the middle of next week, eventually with a mix of northwest and southerly swell. REMAINDER OF THE AREA... A weak cold front passing to the southeast of 30N140W will stall and dissipate later today. Strong southerly winds will precede a stronger cold front that will pass to the southeast of 30N140W on Monday, but stall and weaken over the northwest waters from 30N132W to 22N140W by Tuesday, before becoming diffuse through mid week. Long period northwest swell with seas of 8 to 14 ft continues to move across the waters mainly north of 06N. This will decay below 8 ft from west to east through late Monday, just ahead of another set of long period northwest swell moves into the area, eventually overtaking the entire area from the central coast of the Baja California peninsula to 05N140W through mid week with seas in excess of 8 ft. Seas to 12 to 17 ft will move across the waters north of 20N west of 130W Tuesday into Wednesday. $$ CHRISTENSEN
