000 AXPZ20 KNHC 140833 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0900 UTC Tue Jul 14 2020 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 0600 UTC surface analysis and satellite imagery through 0800 UTC. ...SPECIAL FEATURES... Tropical Depression Six-E is centered near 17.2N 115.1W at 14/0900 UTC moving W at 14 kt. Estimated minimum central pressure is 1007 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Scattered moderate convection is noted from 06N to 18N between 111W and 122W. The system should continue this general motion for the next few days. Some slight strengthening is possible today, and the depression could become a tropical storm before tonight. After that, conditions are unfavorable for further development. Please read the latest NHC Public Advisory at https://www.nhc.noaa.gov/text/MIATCPEP1.shtml and Forecast/ Advisory at https://www.nhc.noaa.gov/text/MIATCMEP1.shtml for more details. ...TROPICAL WAVES... The axis of a tropical wave that extends north into the Caribbean stretches along 82W from Panama to 03N, moving W at 10 to 15 kt. Numerous moderate to isolated strong convection is noted from 03N to 10N between 77W and 84W. The axis of a tropical wave is near 97W, from 02N to Oaxaca, Mexico, moving W at 10 to 15 kt. Scattered moderate to isolated strong convection is noted from 07N to 16N between 91W and 99W. The axis of a tropical wave is near 126W, from 02N to 19N, moving W at 10 to 15 kt. Scattered moderate convection has developed mainly behind this wave, from 06N to 11N between 122W and 126W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from near 09N80W to 11N110W to beyond 10N140W. Aside from the convection noted in the tropical waves and special features sections, scattered moderate convection is noted from 04N to 12N between 84W and 87W, from 06N to 13N between 103W and 111W, and from 09N to 13N between 136W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Tropical Depression Six-E has moved well west of the area and will not longer affect Mexican offshore waters. A low pressure trough over Baja California will lead to fresh to strong SE winds in the northern Gulf of California through this afternoon with peak seas of 5 to 6 ft. For waters W of Baja California, fresh to locally strong NW winds can be expected into late week. High pressure building into the Gulf of Mexico Thu and Fri will likely lead to strong gap winds in and downwind of the Gulf of Tehuantepec from Thu night into early Sun. While current guidance suggest near- gale conditions late Fri, peak seas are anticipated to reach around 8 ft due to the limited area and duration of these gap winds. No significant long-period swell are expected in the Mexican offshore zones for at least the next several days. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Mainly fresh NE to E winds are expected in the Papagayo region through the week, with locally strong winds likely during the overnight and early morning hours. Peak seas may approach 8 ft. Moderate to fresh monsoonal SW winds will prevail over the waters S of 10N into late week with peak seas near 5 to 6 ft. No significant long-period swell are expected in the Central American and equatorial offshore zones for at least the next several days. REMAINDER OF THE AREA... See Special Features section above on Tropical Depression Six-E. This depression could become a tropical storm day, before weakening is likely tonight and Wed. The depression is expected to move rapidly west through the basin, roughly tracking along 16N. By Thursday, this system is expected to be post-tropical, an only a remnant low. Low pressure 1008 mb near 22N132W will continue to move west and be out of the area late Wed. To the northwest, a 1031 mb high is centered 40N148W, and is ridging SE to offshore Baja California. The pressure gradient between the high and low is leading to a fairly broad area of strong E winds just north of the low, along with seas up to 11 ft. Conditions will only slowly improve until late week. Moderate to fresh S winds south of the monsoon trough between 110W and 120W are combining with some SW swell to produce combined seas of 8 to 10 ft. These will progress westward before diminishing on Friday. A weak cold front may slide S to around 25N between 120W and 140W Thu and Fri. The front could be accompanied by fresh north winds and 8 to 10 ft seas. $$ KONARIK
