000 AXPZ20 KNHC 070151 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0115 UTC Thu May 7 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 0000 UTC surface analysis and satellite imagery through 0100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 09N79W to 07W105W. The ITCZ extends from 07N105W to 06N140W. Scattered moderate isolated strong convection is noted from 04N to 07N E of 82W and from 05N to 09N between 116W and 140W. Scattered moderate convection is located from 05N to 12N between 90W and 116W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends from a 1034 mb surface high pressure offshore of northern California through 30N132W to NW of the Revillagigedo Islands. Moderate NW winds are present offshore Baja California Norte along with seas of 8 to 10 ft in NW swell. Gentle winds and 5 to 7 ft seas are noted elsewhere. Northerly gales well offshore of southern California continue to produce NW swell, that will persist off Baja California Norte through Thu evening, while winds diminish. Areas of moderate S to SE winds are expected to develop in the Gulf of California Thu evening into Fri. Gentle to moderate westerly breezes and 3 to 5 ft seas persist across the Mexican offshore waters south of 20N. Smoke from agricultural fires is expected to impact visibility near the shore, especially offshore Chiapas and Oaxaca, through Thu morning. A late season cold front moving through the Gulf of Mexico will deliver near gale force gap winds across the Gulf of Tehuantepec late tonight and again Thu night, with seas building to 10-11 ft. Seas generated by the northerly gap winds will mix with longer period southerly swell reaching the area Thu night. More gap winds are expected in the Gulf of Tehuantepec early Sun through Mon. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh gap winds are occurring across the Papagayo region this evening. Elsewhere light to gentle winds prevail. Seas are 4 to 6 ft through the region. Agricultural fires across Central America are producing areas of smoke and reduced visibilities across the nearshore waters from Tehuantepec to near the Gulf of Fonseca will persist through Thu morning. Fresh gap winds will pulse tonight across the Papagayo region, before increasing to strong Thu night as high pressure builds north of the area. SW long period swell will reach the Galapagos Islands Thu afternoon and Fri, and will likely reach waters off Central America Fri night into the weekend. REMAINDER OF THE AREA... Northerly swell associated with strong to gale force northerly winds off the coast of southern California has moved into the waters west of Guadalupe Island, north of 25N and east of 125W. 1034 mb high pressure centered offshore of northern California is supporting moderate to fresh trade winds farther south into the deep tropics, where seas are 7 to 9 ft in a mix of NW swell and tradewind seas. Seas are 6 to 7 ft elsewhere. The swell is expected to taper off into late week, with seas diminishing below 8 ft Thu night. Meanwhile Southern Hemispheric long period SW swell is beginning to cross he equator east of 125W tonight, and will bring 8 to 10 ft seas south of 11N and east of 125W by late Fri. This swell will subside across the tropics below 8 ft Sat evening as it propagates toward Central America. $$ KONARIK
