000 AXPZ20 KNHC 070949 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 0405 UTC Wed Oct 07 2020 Corrected Remainder of the Area section 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 0000 UTC surface analysis and satellite imagery through 0330 UTC. ...SPECIAL FEATURES... Tropical Storm Norbert is centered near 14.5N 106.9W or about 300 nm south-southwest of Manzanillo, Mexico at 0300 UTC drifting N at 1 kt. Estimated minimum central pressure is 1001 mb. Maximum sustained wind speed 45 kt with gusts to 55 kt. Latest ASCAT data pass depicted the winds associated with the cyclone, and revealed a very small area of tropical storm force winds extending only 20-30 nm from the center. Satellite imagery shows convection associated with Norbert diminishing with time. This convection is of the moderate type intensity located within 90 nm of the center in the SE quadrant. Similar convection is northeast of the center within 30 nm of 15N105W. Norbert is a small cyclone and is forecast to meander or be nearly stationary over the next few days, roughly near the outer boundary or just outside of the offshore waters of SW Mexico. Please read the latest NHC Public Advisory at https://www.nhc.noaa.gov/text/MIATCPEP4.shtml and Forecast/ Advisory at https://www.nhc.noaa.gov/text/MIATCMEP4.shtml for more details. ...TROPICAL WAVES... A tropical wave has its axis along 85W north of 02N to across northern Panama and southern Nicaragua. It is moving westward at 10-15 kt. Scattered moderate to isolated strong convection is occurring from 05N north to over most of Honduras and Costa Rica. A tropical wave has its axis along 100W from 03N to 16N, moving westward near 10 kt. A narrow line of scattered moderate convection is noted behind the wave from 10N to 14N between 98W and 99W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from northern Panama northwestward to southeastern El Salvador, then southwestward to low pressure of 1009 mb near 11N94W and to 10N98W where it breaks down. It resumes at 14N111W to 13N119W to low pressure of 1008 mb near 11N124W and to 12N137W. The ITCZ extends from 12N137W to beyond the area at 11N140W. Scattered moderate to isolated strong convection is within 120 nm north of the trough between 125W- 128W. Scattered moderate convection is within 120 nm south of the trough between 116W-119W and to the southwest of Norbert from 10N to 13N between 107W-110W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see Special Features section for more details on Tropical Storm Norbert. Seas of 8-10 ft will shift northwestward across the far outer offshore waters of SW Mexico to the west of Manzanillo through Thu. As Marie continues to move westward over the far western section of the area, a ridge will finally become established over the offshore waters of Baja California bringing gentle to moderate NW-N winds with seas of 5-7 ft. As it is normal for this time of the year, mainly light to gentle southerly winds are expected in the Gulf of California during the next several days. Strong north to northeast winds across the Gulf of Tehuantepec will gradually diminish through the rest of the week. Seas of 8-10 ft there will slowly subside through Wed. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate to locally fresh southwesterly winds are expected S of the monsoon trough with mainly light to gentle winds north of it. Seas generated by the gale-force gap winds in the Tehuantepec region will continue to propagate across the offshore waters of Guatemala and El Salvador through tonight. REMAINDER OF THE AREA...Corrected Please see Special Features section above for details on Tropical Storm Norbert. The Post-Tropical Cyclone Marie is centered near 23N136W or about 1450 nm to the west of the southern tip of Baja California at 0300 UTC moving WNW at 7 kt. Estimated minimum central pressure is 1005 mb. Maximum sustained wind speed has diminished to 30 kt with gusts to 40 kt. Marie is devoid of convection as latest satellite imagery currently depicts the former tropical cyclone as a large swirl of broken to overcast low and mid-level clouds from 19N to 27N and between 132W-140W. Scattered mainly-low top showers and patches of rain are possible underneath these clouds. The pressure gradient between Marie and high pressure to its north is supporting a large wind field of strong to near gale- force winds in the NE quadrant along with wave heights there in the 11-16 ft range. Gradual weakening is forecast during the next 48 hours as the remnant low cloud swirl moves over the rest of the far western part of the area and crosses to west of 140W late Thu night into early Fri at which time wave heights are expected to lower below 8 ft along and near 140W. Otherwise, gentle to moderate winds are occurring N of the monsoon while moderate to locally fresh winds prevail to the south of the monsoon trough. Seas greater than 8 ft generated by former tropical cyclone Marie cover most of the waters north of 10N and west of a line from 28N130W to 16N137W. Long-period southeast swell from the Southern Hemisphere has reached north to near 10N and between 100W-130W. This swell will continue to propagate northward to near 13N by late Wed, $$ Aguirre
