Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Apr 22 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 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N79W to 05N93W. The ITCZ continues from 05N93W to beyond 05N140W. Scattered moderate convection is noted from 03N to 08N W of 122W. Scattered showers are noted along the trough. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A surface ridge extends from a high pressure centered well N of the area to the Revillagigedo Islands. The pressure gradient between this area of high pressure and a trough western Mexico is supporting gentle to moderate winds west of the Baja California peninsula. Light to gentle winds prevail elsewhere. Seas are in the 4-6 ft range over the open waters off Mexico, and 3 ft or less over the Gulf of California. For the forecast, gentle to moderate winds winds and moderate seas will persist west of the Baja California peninsula through the middle of this week. Winds will then locally freshen Thu and Fri. Fresh to strong gap winds will develop in the Gulf of Tehuantepec late tonight, and continue through Tue before diminishing. Seas will peak near 10 ft Mon night with the gap winds. Elsewhere, light to gentle winds and moderate seas will prevail. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR Light to gentle winds, and seas of 4-6 ft prevail across the discussion waters. For the forecast, light to gentle breezes will persist across the region through the week. Wave heights will be mostly 4 to 6 ft primarily in SW swell, building to 5 to 7 ft off Ecuador tonight. Moderate to occasionally fresh gap winds will develop in the Gulf of Papagayo Tue, then continue through the week. ...REMAINDER OF THE AREA... A high pressure is centered well N of the area, with ridge extending SE to near the Revillagigedo Islands. The pressure gradient between the area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh trade winds from 05N to 20N between 120W and 140W, where seas are in the 7-9 ft range. A surface trough is over the NW waters from 30N133W to 26N139W. Moderate winds and seas of 6-7 ft are west of the frontal boundary. Gentle to moderate winds are noted N of 28N between 120W and 128W where the pressure gradient is locally tighter between the ridge and trough over the Gulf of California. Gentle winds are noted elsewhere across the discussion waters. Aside from the areas mentioned above, seas are in the 4-6 ft range. For the forecast, wind speeds and wave heights will remain similar into early this week, with an area of 8 ft seas persisting roughly from 08N to 12N W of 130W with N swell mixing with NE wind waves. The trough will dissipate tonight. Looking ahead, a weak surface low will enter the north-central portion of our waters by mid-week enhancing winds/seas.
