000 AXPZ20 KNHC 020948 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 620 UTC Mon Mar 2 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 0900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The ITCZ extends from 04N95W to 01N120W to 03N140W. No significant convection is noted. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A cold front is approaching Guadalupe Island and will move across the waters off Baja California through Tue, then stall and dissipate over the Revillagigedo Islands by mid week. Fresh to strong NW winds will follow the front, mainly impacting waters north of Cabo San Lazaro. The main impact will be seas. Large NW swell is accompanying the front, with seas 12 to 17 ft moving into the waters of Baja California Norte today. This will subside a little through tonight as it travels south, but seas of 8 to 14 ft off the entire Baja California peninsula and into the Revillagigedo Islands through Tue. A recent scatterometer satellite pass confirmed fresh to strong SW to W gap winds were still occurring over the northern Gulf of California ahead of the approaching cold front. Seas are near 8 ft in the northern Gulf in association with these winds. These conditions will diminish later today. A secondary surge of fresh W to NW winds will follow the front tonight into Tue. Gentle to moderate winds with 5 to 7 ft seas in mixed swell persist farther south in Mexican offshore waters. Looking ahead, a gale force Tehuantepec gap wind event is possible Thu night through Fri night as a strong cold front crosses the Gulf of Mexico. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gulf of Papagayo: Fresh winds gap winds are reported at Liberia Costa Rica, near the Gulf of Papagayo. This is an indication of stronger gap winds over the offshore waters. High pressure well north of the area behind a cold front that entered the Caribbean has been supporting gale force the past couple of days, but the pressure gradient has been weakening as the high pressure shifts farther east and the front dissipates over the western Caribbean. Fresh to near gale force offshore winds will continue through this morning, with mainly fresh to locally strong winds for the remainder of the week. Meanwhile, seas of 8-10 ft downwind of these winds will remain possible this morning before subsiding. Elsewhere, fresh to strong winds will continue over and downstream of the Gulf of Panama through this morning, then moderate to fresh through the remainder of the week. Seas of 8-9 ft associated with these winds will subside tonight as the winds diminish. REMAINDER OF THE AREA... A cold front has moved into the waters north of 22N, and will continue to near 20N through Tue before stalling and dissipating. High pressure north of the cold front is supporting a broad area of fresh to strong winds mainly north of 05N and west of 120W, as noted in recent scatterometer satellite data. Concurrent altimeter satellite passes show seas of 8 to 12 ft. Winds and seas will diminish north of 20N by late week, with fresh trade winds persisting. Farther east in the deep tropics, fresh trade winds along with swell originating from earlier gap wind events farther east will diminish later today over waters west of 120W. $$ Christensen
