000 AXPZ20 KNHC 110837 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon Apr 11 2022 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 0830 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07N77W to 06N81W to 06N103W. The ITCZ continues from 06N103W to 08N121W. It resumes west of a couple of perturbations from 04N131W TO 04N140W. Scattered moderate isolated strong convection is noted from 00N to 05N east of 83W, from 02N to 08N between 86W and 107W, and from 03N to 13N between 110W and 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Fresh SE to S winds prevail across the central and northern Gulf of California, with locally strong winds in the northern Gulf. Moderate to fresh NW winds prevail west of Baja California Norte. Light to gentle winds prevail elsewhere across the open waters off Mexico. Seas are 3-5 ft across the Gulf of California, 8-12 ft west of Baja California Norte, 6-9 ft off Baja California Sur in NW swell, and 4-5 ft elsewhere offshore Mexico. For the forecast, fresh to strong S to SW winds will persist across the northern Gulf of California through Tue morning. Northerly swell will prevail west of the Baja California peninsula today. A cold front will move into the northern portion of the area by early Tue morning. Fresh to strong NW winds are expected behind the front to the west of Baja California Norte, with fresh winds off Baja California Sur. A reinforcing set of northerly swell will enter the area behind the front. This will maintain wave heights in excess of 8 ft west of the Baja California peninsula through early Thu. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to strong NE winds are noted across the Gulf of Papagayo region. Moderate to fresh N to NE winds are over the Gulf of Panama. Light to gentle winds prevail elsewhere, except for gentle to moderate southerlies offshore of Ecuador. Seas are in the 4-6 ft range, except 6-8 ft over the Papagayo region. For the forecast, fresh to strong winds will pulse in the Papagayo region through the week. Fresh winds will pulse in the Gulf of Panama tonight, gradually diminishing to gentle through midweek. Gentle to moderate S winds will prevail between Ecuador and the Galapagos Islands through the next few days. Mainly light to gentle winds are expected elsewhere. S to SW swell will increase seas through early Tue to the south of the Galapagos Islands and well to the west of Ecuador. REMAINDER OF THE AREA High pressure of 1034 mb is centered north of the area near 36N142W. This pressure gradient between this area of high pressure and low pressure off the coast of California is producing fresh to strong NE winds over the waters north of 25N between 120W and 130W. Seas in this area are in the 10-14 ft range. Moderate to locally fresh trade winds are elsewhere north of the ITCZ and west of 120W, with gentle to moderate winds prevailing elsewhere. Seas are in the 6-8 ft range. Southern Hemisphere swell is affecting the area south of 05N between 100W and 120W, with seas in the 8-9 ft range. For the forecast, the area of fresh to strong winds over the northwest part of the area will start to diminish today. Swell generated from these winds will spread southward, with seas greater than 8 ft covering much of the waters north of 10N and west of 115W by tonight. A cold front will enter the northern waters by early Tue morning, then extend from 31N113W to 26N121W to 30N134W by midday Tue. The front will continue southward before dissipating Tue night. The front will bring a reinforcing northerly swell to the area east of 125W and north of 22N Tue through Wed. Southerly swell from the Southern Hemisphere will continue to affect areas south of 05N between the Galapagos Islands and 125W through the early part of next week. $$ AL
