{"msg": "722\nAXPZ20 KNHC 090857\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n1005 UTC Mon Nov 9 2026\nTropical Weather Discussion for the eastern Pacific Ocean from\n03.4S to 30N, east of 120W including the Gulf of California, and\nfrom the Equator to 30N, between 120W and 140W. The following\ninformation is based on satellite imagery, weather observations,\nradar, and meteorological analysis.\nBased on 0600 UTC surface analysis and satellite imagery through\n0855 UTC.\n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough extends from 09N83W to 05N94W. The ITCZ stretches\nfrom 05N94W to 05N110W and to 06N125W and then from 10N132W to beyond\n08N140W. Scattered moderate convection is observed from 02N to 06N\nand between 95W and 108W. Similar convection is noted from 10N to\n16N and between 115W and 133W and from 02N to 08N and west of 135W.\n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nHigh pressure centered north of the area continues to support \nfresh to strong northerly winds and seas of 6-8 ft across the \nGulf of Tehuantepec. A recent scatterometer satellite pass\ncaptured winds up to 25 kt. In the remainder of the basin, a \nbroad subtropical ridge centered off California extends \nsoutheastward to the Revillagigedo Islands, sustaining moderate \nor weaker winds. Seas of 7-9 ft are found in the offshore waters \nof Baja California due to a long-period NW swell. This was\nconfirmed by a recent altimeter satellite pass. Elsewhere, \nslight to moderate seas prevail.\nFor the forecast, fresh to strong northerly winds and rough seas\nto 8 ft will pulse in the Gulf of Tehuantepec through Wed \nmorning. Another gap wind event may develop in the Gulf of \nTehuantepec by Thu night, possibly reaching gale-force into the \nupcoming weekend. Rough seas in the offshore waters of Baja\nCalifornia will diminish midweek. Looking ahead, fresh to strong\nwinds and rough seas approaching 12 ft may reach the offshore \nwaters of Baja California late in the week, associated with a \nfrontal system.\n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nA weak 1008 mb low pressure, Invest EP96, located about 130 nm\nsouth of El Salvador is producing some showers, located well\nnorth of the center. The storm activity has diminished over the\npast few hours due to strong wind shear. A recent scatterometer\nsatellite pass showed fresh to strong winds north of the low,\nalso affecting parts of the nearshore waters of Nicaragua. Moderate\nseas are occurring north of 10N and east of 91W. Elsewhere, winds\nare moderate or weaker with seas 4-7 ft in mixed SW and W swell.\nFor the forecast, environmental conditions are forecast to \nbecome less favorable for additional development over the next \nseveral days as EP96 moves westward or west-southwestward away \nfrom land, and the chances of it becoming a short-lived tropical \ncyclone are decreasing. Regardless, this system is expected to \nbring periods of heavy rain to portions of Central America over \nthe next day or so. The system has a low chance of development\nover the next 48 hours. Meanwhile, fresh to locally strong\neasterly trade winds will funnel across the Papagayo region \nthrough midweek. Moderate to locally fresh winds will pulse in \nthe Gulf of Panama through the middle of the week. Otherwise, \nmoderate or weaker winds, and moderate seas, will prevail.\n...REMAINDER OF THE AREA...\nA broad subtropical ridge centered north of the tropical eastern\nPacific dominates the basin, supporting moderate to fresh \neasterly winds and rough to very rough seas to 13 ft north of \n10N and west of 115W. Meanwhile, moderate to fresh SE winds and \nseas to 9 ft are occurring south of 03N and east of 120W. \nElsewhere, moderate or weaker winds and moderate seas prevail.\nFor the forecast, the surface ridge will amplify some, increasing\nthe trades to fresh from 10N-22N west of 125W tonight into Wed.\nThe large NW swell in the western waters will reach from 20N140W\nto 20N120W Tue night. The mixed swell over the equatorial waters\nwill persist for the next several days. Looking ahead, a strong \ncold front will reach our NW border at 30N140W early Wed, bringing\nwith it fresh to strong NW winds and very large seas north of \n20N through the end of the week. Reinforcing NW swell may arrive\nFri to the NW waters producing rough to very rough seas.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1225995934200463363", "issued": "2026-11-09T10:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1225995934200463363"}
