{"msg": "046\nAXPZ20 KNHC 101002\nTWDEP \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n1005 UTC Thu Sep 10 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\n0950 UTC.\n...SPECIAL FEATURES...\nTropical Storm Norbert is centered near 16.4N 117.9W at 10/0900\nUTC, moving west at 11 kt. Estimated minimum central pressure is\n1004 mb. Maximum sustained wind speed is 35 kt with gusts to 45\nkt. Peak seas are 12 ft within 90 nm NE quadrant of the center. \nNumerous moderate to strong convection is noted from 13N to 19N \nbetween 113W and 118W. Scattered moderate to isolated strong \nconvection is elsewhere from 03N to 11N between 117W and 125W. A\ngenerally westward motion is expected over the next couple of \ndays. Some strengthening is forecast during the next 48 hours, \nand the depression is expected to become a tropical storm on \nThursday. \nPlease read the latest HIGH SEAS FORECAST issued by the National\nHurricane Center at website - \nhttps://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest \nFourteen-E NHC Forecast/Advisory and Public Advisory at \nwww.hurricanes.gov for more details.\n...TROPICAL WAVES...\nA tropical wave is along 92W north of 02N through Guatemala. The\nwave is moving westward at about 15 kt. Scattered moderate to \nisolated strong conveciton is from 04N to 15N between 90W and \n100W.\n \nA tropical wave has its axis along 105W north of 02N. It is \nmoving westward at 15 to 20 kt. Scattered moderate to isolated \nstrong convection is from 03N to 22N between 100W and 111W.\n...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...\nThe monsoon trough axis extends from 09N84W to 08N100W to \n10N111W, then continues SW of T.S. Norbert from 13N119W to \n10N140W. Scattered moderate to strong convection is from 03N to \n11N E of 90W. Scattered moderate convection is from 03N to 10N W\nof 136W. \n...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...\nFresh winds and rough seas associated with the outer periphery \nof Tropical Storm Norbert are affecting the outer offshores of\nthe tip of Baja California Sur. Fresh to strong N gap winds \ncontinue across the Tehuantepec region and downwind to near 14N. \nModerate to locally rough seas are with these winds. Light to \ngentle winds dominate the offshore waters of Baja California \nunder the influence of a weak ridge centered near 27N124W. \nLight to gentle winds and moderate seas are present elsewhere \nacross the remaining Mexican offshore waters. \nFor the forecast, Norbert will move to 16.6N 119.9W this \nafternoon, 16.7N 122.5W Fri morning, 16.7N 124.8W Fri afternoon,\n16.9N 126.9W Sat morning, 17.3N 128.9W Sat afternoon, and 17.8N \n130.4W Sun morning. Norbert will strengthen to a hurricane over \n18.5N 133.5W early Mon. A trailing tropical wave is forecast to \nprovide mainly moderate to fresh SE winds to the SW Mexican \noffshore waters through today. Otherwise, fresh to strong N to NE\ngap winds will continue to pulse across the Gulf of Tehuantepec \nthrough early Fri. \n...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, \nAND WITHIN 750 NM OF ECUADOR...\nFresh to strong northeast to east winds are blowing in the Papagayo\nregion and downwind to 90W, with moderate to rough. Gentle to \nmoderate SE to S winds are across the offshores between Ecuador \nand the Galapagos Islands along with moderate seas. Otherwise, \nmoderate or weaker winds with slight to moderate seas prevail\nelsewhere.\nFor the forecast, high pressure north of the area will support \nfresh to strong easterly winds, and moderate to rough seas across\nthe Gulf of Papagayo region through Fri, then mainly moderate to\nfresh winds and moderate seas are expected. Meanwhile, moderate \nto fresh southerly winds are expected over the waters between \nEcuador and the Galapagos through tonight, then diminishing some\nafterward. Moderate or lighter winds and moderate seas in long\nperiod SW swell are forecast elsewhere.\n...REMAINDER OF THE AREA...\nPlease, see the Special Features section for more information \nabout Tropical Storm Norbert. \nTropical Storm Norbert is near 16.4N 117.9W at 2 AM PDT, and is\nmoving west at 11 kt. Maximum sustained winds are 35 kt with\ngusts to 45 kt, and the minimum central pressure is 1004 mb. \nElsewhere, moderate or weaker winds along with seas of 5 to 7 ft \nare over the remainder of the tropical eastern Pacific. \nFor the forecast, Norbert will move to 16.6N 119.9W this \nafternoon, 16.7N 122.5W Fri morning, 16.7N 124.8W Fri afternoon, \n16.9N 126.9W Sat morning, 17.3N 128.9W Sat afternoon, and 17.8N \n130.4W Sun morning. Norbert will strengthen to a hurricane over  \n18.5N 133.5W early Mon.  \nLooking ahead, an area of low pressure is forecast to form \nseveral hundred miles south of the southern tip of the Baja \nCalifornia Peninsula this weekend or early next week. Some \ngradual development is possible thereafter, and a tropical \ndepression could form early next week while the system moves \ngenerally westward. This system has a medium chance of tropical \ncyclone formation through 7 days.\n", "title": "Eastern Pacific Tropical Weather Discussion", "id": "1209021687272210434", "issued": "2026-09-10T10:05:00Z", "wmo": "AXPZ20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1209021687272210434"}
