000 AXPZ20 KNHC 110328 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Thu Nov 11 2021 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0000 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N74W to 06.5N97W. The ITCZ extends from 06.5N97W to 07N105W to 08.5N112W, then resumes from 09.5N134W to beyond 09.5N140W. Scattered moderate convection is noted from 04.5N to 07.5N between 78W and 81W. Scattered moderate isolated strong convection is noted from 09.5N to 14.5N between 114W and 122W, from 12.5N to 16.5N between 126.5W and 129.5W, and from 08.5N to 12N W of 133W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO A surface ridge extends from 1026 mb high pressure W of Baja California Norte southeastward to near the Revillagigedo Islands. The pressure gradient between the ridge and a trough over NW Mexico has strengthened slightly today and is supporting fresh to strong northerly winds from the waters of Baja California Norte to offshore of Cabo San Lazaro, while moderate winds persist off Baja California Sur. Moderate to fresh winds are also found over most of the Gulf of California. Light to gentle winds prevail over the remainder of the open waters off SW Mexico. Wind continue to diminish across the Gulf of Tehuantepec this evening with moderate NE winds and seas of 4-5 ft. Seas of 7-10 ft prevail west of the Baja California peninsula, and 4-6 ft elsewhere over the open waters off Mexico. Seas are in the 3-5 ft range in the Gulf of California. Fresh to strong winds offshore of Baja California will gradually weaken tonight through Thu as the high center shifts northward. Fresh N winds inside the Gulf of California will prevail through Thu afternoon. Strong gap winds will return to the Gulf of Tehuantepec region Fri through Mon. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Moderate gap winds prevail across the Papagayo region, with gentle to moderate winds elsewhere N of the monsoon trough. Gentle to moderate SW to S winds prevail S of the monsoon trough. Seas of 4-6 ft prevail in SW swell across the offshore waters. Gentle to moderate S to SW winds will persist south of the monsoon through the forecast period. Moderate to fresh gap winds will return to the Papagayo region over the weekend. REMAINDER OF THE AREA... 1026 mb high pressure is centered near 34N130W and extends a ridge WSW through 29N140W. The resultant pressure gradient between the high and lower pressure within the monsoon trough and in the vicinity of the ITCZ is supporting moderate to fresh NE to E winds N of the ITCZ and monsoon trough to near 23N and W of 118W, with gentle to moderate winds N of 25N. Gentle to moderate winds prevail south of the monsoon trough and ITCZ. The remnants of Sandra, along 130W, and Terry, along 119W, are accompanied by areas of 25 kt winds to their north, and higher seas of 11-13 ft. Elsewhere, seas are in the 8-10 ft range in mixed NW and NE swell across the trade wind belt west 110W. Seas in the 6-8 ft range prevail elsewhere. The high pressure ridge will remain across the northern waters, maintaining a zone of fresh trade winds S of 20N throughout most of the week. The remnants of Sandra and Terry will move westward through the trade wind zone to maintain a broad zone of strong trades and seas to 10-12 ft. $$ Stripling
