000 AXPZ20 KNHC 251005 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 932 UTC Tue Feb 25 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 0915 UTC. ...Special FEATURES... Gulf of Tehuantepec Storm Warning: A strong cold front will move across the Gulf of Mexico on Wed. The pressure gradient between high pressure building in the wake of the cold front and the equatorial trough in the eastern north Pacific will tighten and support the next gap wind event over the Gulf of Tehuantepec starting Wed afternoon. Winds are forecast to reach minimal storm force by Wed night. Winds will diminish to gale force on Thu, and prevail through early Sun. Seas with this upcoming event are forecast to peak near 23 ft Thu morning. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07N84W to 03N100W. The ITCZ continues from 03N100W to 03N120W to 03N140W. Scattered moderate convection is from 01N to 07N between 87W and 100W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of California: A surface ridge extends across the offshore waters off the Baja California peninsula while an area of low pres is located over central Mexico. The pressure gradient between these features is supporting moderate to fresh NW-N winds across the Gulf of California. High pressure building across the Great Basin region will strengthen the winds over most of the Gulf of California today. Strong to locally near gale force winds are expected to continue through Thu morning with seas building to 9 ft mainly S of 27N on Wed. Elsewhere, high pressure prevails over the offshore waters west of the Baja California peninsula supporting mainly moderate NW to N winds. A set of NW swell propagating across the waters W of Baja California will continue to spread southward, bringing seas to 9 ft west of the Baja peninsula to near the Revillagigedo Islands today. Seas will start to subside early on Wed. Fresh to strong winds are forecast to come through the mountain passages in Baja California Norte into the Pacific offshore waters N of Punta Eugenia on Wed as winds increase in the Gulf of California. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gulf of Papagayo: Winds will strengthen to strong Thu evening as high pressure builds N of the area. Strong to near gale force winds are expected on Fri morning, possibly reaching minimal gale force Sat evening through Sun morning. Gulf of Panama: Winds will increase to strong early on Fri as high pressure builds N of the area. Strong winds will prevail through Sun with seas building to 8 ft. Elsewhere, gentle to moderate winds and seas of 4-6 ft will prevail through the weekend. REMAINDER OF THE AREA... A ridge extends from high pressure of 1035 mb, centered N of the area near 35N133W, 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 20N and W of 125W. Seas in the 9-10 ft range prevails over this area. The area of high pressure will start to weaken through midweek. This will decrease aerial coverage of the fresh to strong trades. Seas of 8 ft or greater prevail over much of the forecast waters W of 110W in a broad mix of swells. The swell will gradually subside over the next couple of days, and aerial coverage of seas 8 ft or greater will decrease. By midweek, much of the waters W of 110W will subside below 8 ft. A new set of long period NW swell will reach the NW waters on Wed and spread SE. Seas will peak near 11 ft over the far NW waters Wed night before starting to subside. $$ Ramos
