####018003408#### AXPZ20 KNHC 201930 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sat Apr 20 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 1800 UTC surface analysis and satellite imagery through 2030 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N78W to 06N83W to 08N97W to 06N115W. The ITCZ continues from 06N115W to 06N125W. It resumes from 05N133W to beyond 04N140W. Scattered moderate convection is noted from 05N to 10N between 84W and 91W, from 04N to 10N between 100W and 121W, and from 01N to 04N between 135W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends from 1024 mb high pressure centered near 30N131W SE to near the Revillagigedo Islands. The pressure gradient between this area of high pressure and a trough over the Gulf of California is supporting moderate winds west of the Baja California peninsula. Light to gentle winds prevail elsewhere. Seas are in the 5-6 ft range over the open waters off Mexico, and 1-3 ft 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 next week. Fresh to strong gap winds will develop in the Gulf of Tehuantepec Sun night, and continue through Tue before diminishing. Seas will peak near 9 ft Mon night with these 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 5-6MONSOON TROUGH AXIS EXTENDS FROM ITCZ AXIS EXTENDS FROM ft prevail across the discussion waters. For the forecast, light to gentle breezes will persist across the region into the middle of next week. Wave heights will be mostly 4 to 6 ft primarily in SW swell, building to 5 to 7 ft off Ecuador Sun. Looking ahead, moderate to fresh gap winds may develop in the Gulf of Papagayo by mid-week. ...REMAINDER OF THE AREA... A 1024 mb high pressure is centered near 30N131W, with ridge extending SE to near the Revillagigedo Islands. The pressure gradient between the area of high pressure, lower pressure in the vicinity of the ITCZ, and a surface trough from 10N128W to 03N128W is supporting moderate to fresh trade winds from 05N to 20N between 120W and 140W, where seas are in the 7-8 ft range. A frontal boundary is over the NW waters from 30N133W to 26N138W. Moderate winds and seas of 5-6 ft are west of the frontal boundary. Light winds are in the vicinity of the high center, with light to gentle winds noted elsewhere across the discussion waters. Aside from the area where fresh trades are, seas are in the 5-7 ft range. For the forecast, wind speeds and wave heights will remain similar into early next 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 frontal trough will dissipate this weekend. $$ AL ####018003408#### AXPZ20 KNHC 201931 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sat Apr 20 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.
