000 AXPZ20 KNHC 100402 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Wed Nov 10 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 0310 UTC. ...SPECIAL FEATURES... The remnant low of Sandra is centered near 11.9N 114.1W at 0300 UTC moving W at 12 kt. Estimated minimum central pressure is 1008 mb. Maximum sustained wind speed is 25 kt with gusts to 35 kt. The low level center of Sandra has become completely exposed with no significant convection noted near the center. Associated convection is described below along the ITCZ. The remnant low of Sandra will continue to move W to WSW over the next few days, and is expected to weaken to a trough tonight.

Tropical Depression Terry is centered near 11.9N 114.1W at 0300 UTC moving W at 12 kt. Estimated minimum central pressure is 1008 mb. Maximum sustained wind speed is 25 kt with gusts to 35 kt. Scattered moderate to strong convection is noted from 09.5N TO 15N between 110W AND 118W. Terry is expected to continue on a W to WSW track over the next 48 hours. Due to its small size and trajectory near the ITCZ and associated moisture, it has a brief opportunity to strengthen slightly late Wed before slowly weakening to a remnant low late Thu or Fri.

The monsoon trough extends from 10N74W to 05N95W to 08N104.5W. The ITCZ extends from 10N126W to beyond 08.5N140W. Scattered moderate isolated strong convection is noted from 05N to 10N E of 92W. Scattered moderate to strong convection is noted from 09N to 12N W of 129W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Strong winds to near 30 kt, and seas to 10 ft, prevail over the Gulf of Tehuantepec N of 14N. Elsewhere, a surface ridge extends W of the Baja California peninsula. The tightening pressure gradient between the ridge and a trough over the Gulf of California is supporting moderate to fresh northerly winds. Gentle to moderate winds prevail elsewhere across the open waters off Mexico as well as over the Gulf of California. Seas are in the 6-8 ft range off Baja California Norte, and 5-7 ft elsewhere over the open waters off Mexico. Seas are in the 1-3 ft range in the Gulf of California. Strong gap winds will prevail across the Gulf of Tehuantepec through early Wed, pulsing to just below gale force tonight. Winds will become fresh tonight through early Thu over the waters west of Baja California, except for strong winds gradually spreading S to offshore of Cabo San Lazaro through Wed evening. Moderate N winds inside the Gulf of California will become fresh Wed afternoon through Thu afternoon. Strong gap winds will return to Tehuantepec Fri through Sun. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR The pressure gradient between high pressure over the SE United States, a weakening cold front across the western Caribbean, and the eastern Pacific monsoon trough is supporting moderate to fresh gap winds across the Papagayo region, and moderate gap winds across the Gulf of Fonseca. Elsewhere light to gentle NE winds are N of the monsoon trough. Gentle to moderate SW to S winds prevail S of the monsoon trough. Seas of 5-6 ft prevail in SW swell across the offshore waters, except reaching near 8 ft over the Gulf of Papagayo. Fresh to strong gap winds will continue over the Gulf of Papagayo through midday Wed before diminishing through the remainder of the week. 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... Please see special features section above for more on T.D. Terry and the remnant low of Sandra. The pressure gradient between 1026 mb high pressure near 28N128W 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 21N and W of 115W, with gentle to moderate winds N of 21N. Gentle to moderate winds prevail south of the monsoon trough and ITCZ. Seas are in the 7-9 ft range in mixed NW and NE swell over the waters north of 10N and west 115W, except higher N of the remnants of Sandra. Seas in the 6-8 ft range prevail elsewhere. High pressure 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 will move westward through the trade wind zone to produce a broad area of strong trades and seas to around 10 ft. $$ Stripling
