000 AXPZ20 KNHC 240901 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 615 UTC Mon Feb 24 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... A surface trough extends from 06N81W to 05N91W to 03N100W. The ITCZ continues from 03N100W to 02N120W to 02N140W. Scattered moderate isolated strong convection is noted from 01N to 05N between 90W and 113W, and from 04N to 12N between 124W and 134W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of Tehuantepec: Return flow has established in the Gulf of Mexico, allowing for the winds in Tehuantepec to diminish to light to gentle speeds. Large swell generated by a former gap wind event is currently producing a large area of 8-9 ft seas from 03S to 12N between 96W and 113W. This area of 8 ft seas will continue to propagate westward, merging with an area of NW swell this morning. Looking ahead, the next strong gap wind event across the Tehuantepec region, possibly reaching storm force, is forecast to commence on Wed evening and prevail over the weekend. Elsewhere high pressure prevails over the offshore waters west of the Baja California peninsula supporting moderate to fresh NW to N winds west of Baja California. A set of NW swell propagating across the waters of Baja California Norte will continue to spread southward with seas of 8-9 ft reaching the Revillagigedo Islands this evening. These seas will subside Wed morning. Otherwise, fresh to strong NE winds are forecast for the Sebastian Vizcaino Bay Wed morning through Wed evening due to an increase in the pressure gradient in the Gulf of California. Gulf of California: Moderate to fresh NW winds along the gulf will increase to fresh to strong by Tue night as the pressure gradient tighten between a strong ridge building in Colorado and a deepening trough along NW Mexico. Locally near gale force winds are possible by Wed morning when seas are expected to build to 8 ft over the central and southern gulf waters. Winds will diminish to moderate to fresh by Thu and to a gentle breeze on Fri. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gulf of Papagayo: Fresh to strong winds will continue through this morning before diminishing. Winds will once again strengthen Thu evening as high pressure builds N of the area. Gulf of Panama: Fresh to occasionally strong north winds will prevail across the Gulf of Panama and downstream through this morning before diminishing. Winds will once again increase Fri as high pressure builds N of the area. Elsewhere, light to gentle winds and seas of 4-6 ft will prevail through Fri. REMAINDER OF THE AREA... A ridge extends from high pressure of 1035 mb, centered N of the area near 36N132W, to near the Revillagigedo Islands. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting fresh to strong tradewinds N of the ITCZ to near 25N and W of 120W. Seas in the 9-12 ft range prevails over this area. The high pressure will remain nearly stationary today, maintaining this area of fresh to strong trades. The high center will then start to drift NE and weaken by Tue, helping to diminish the trades. Otherwise, long period NW swell will start propagating across the NW waters Tue night and reach the Baja California Norte adjacent waters Thu evening. Seas with this new swell will range between 8-11 ft in the Pacific open waters. $$ Ramos
