####018004164#### AXPZ20 KNHC 261604 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Fri Apr 26 2024 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 1200 UTC surface analysis and satellite imagery through 1550 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The equatorial trough extends from 07N78W to 08N100W to 07N120W. The ITCZ continues from 07N120W to 05N130W to beyond 05N140W. Scattered moderate convection is noted from 00N to 09N E of 89W, from 03N to 13N W of 101W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A 1033 mb center of high pressure extends a broad ridge southeastward to the offshore waters of Baja California. The pressure gradient between the ridge and a surface trough over NW and central Mexico is supporting moderate to fresh NW winds across the Baja California waters, where seas are 5 to 8 ft in NW swell. Gentle to moderate SW to W winds are inside the northern Gulf of California. NW winds of the same speed are across the remaining Gulf. Seas along the Gulf are 2 to 4 ft. Mainly gentle W to NW winds and seas at 4 to 5 ft prevail across the remainder of the S and SW Mexican offshore waters in SW swell. For the forecast, strong high pressure will continue across the NE Pacific to sustain moderate to fresh NW winds across the Baja offshore waters, becoming locally strong during the afternoon and evening hours through Sat night. Westerly gap winds are expected to develop inside the Gulf of California today, and increase to fresh to strong across the northern and central portions Fri evening through early Sat morning. The high pressure will move east and weaken modestly Sun through the middle of next week, leading to weakening winds across the area waters. Moderate NW swell will build across the Baja waters today then become reinforced over the weekend, with seas building to 8 to 11 ft across the outer waters of Baja Norte Sat night. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Scattered showers and isolated tstms prevail across the offshore waters of Costa Rica, Panama and between the Galapagos Islands and Ecuador. Fresh easterly gap winds and seas of 5 to 7 ft are noted across the Papagayo region, extending offshore to 92W. Light to gentle variable winds with 3 to 5 ft seas are present elsewhere in SW swell. For the forecast, fresh to strong easterly gap winds are expected across the Papagayo region tonight, then moderate to fresh winds with moderate seas are forecast through Sat morning. Moderate to fresh N winds will pulse at night in the Gulf of Panama until Sat morning. Gentle to locally moderate winds with moderate seas will prevail elsewhere through Mon before new S swell raises seas across the regional waters Mon night and Tue. ...REMAINDER OF THE AREA... A 1033 mb center of high pressure extends a broad ridge S-SE across the waters north of the ITCZ and west of 110W. Moderate N to NE winds with seas at 5 to 6 ft dominate the waters north of 21N and west of 120W. Moderate to fresh trades and 6 to 9 ft seas exist from 07N to 21N and W of 110W, with locally strong winds and seas 8 to 10 ft west of 134W. Gentle to moderate E to SE winds and 5 to 6 ft seas in moderate, cross equatorial S swell prevail near and S of the ITCZ. For the forecast, the moderate to fresh trade winds will continue S of 21N and west of 120W through Mon, occasionally pulsing to strong. This will maintain seas at 6 to 9 ft south of the ridge. Moderate to fresh N to NE winds and seas at 7 to 10 ft are expected north of 20N and east of 125W today through Mon. Little change is forecast across the remainder of the waters through early next week. $$ Ramos
