000 AXPZ20 KNHC 121545 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Wed May 12 2021 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 1500 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N84W to 10N105W to 09N124W. The ITCZ extends from 09N124W to 06N132W to 04N140W. Scattered moderate and isolated strong convection is noted from 03N to 09N between 78W to 90 and from 05N to 14N between 91W to 111W. Scattered moderate convection is from 08N to 12N between 113W to 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The remnant low pressure of Andres is located SSW of the Revillagigedo Islands near 15N114W and is moving west-northwest at 5-10 kt. Seas are near 7 ft. Along Baja California, northerly gentle to moderate winds are noted with light winds across the Gulf of California. Seas range 5-6 ft in this area with 3 ft or less in the Gulf of California. Elsewhere, light and variable winds prevail. Hazy or smokey conditions may be evident near the coast south of Cabo Corrientes to the Tehuantepec region, but a slight southerly component to the winds along with afternoon sea breezes are probably keeping most of these conditions confined to onshore for now. For the forecast, the seas around the Revillagigedo Islands will continue to subside this morning as the remnant low of Andres dissipates farther south. Elsewhere, fresh southerly winds will pulse in the northern Gulf of California this weekend, increasing to fresh to strong Sat night as a trough moves through the area with seas to 4 ft. Gentle to moderate winds will prevail elsewhere. A moderate NW swell will subside in the waters west of Baja California through Thu, with another set arriving Sat. Farther south, building high pressure in the Gulf of Mexico may allow strong gap winds in the Tehuantepec region Thu through Sat with building seas. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Fresh to strong winds are in the Papagayo region, with gentle to moderate winds elsewhere. Seas are in the 3-6 ft range in mixed long period NW and SW swell, except 5-7 offshore of Ecuador and to 7 ft in the Papagayo region. For the forecast, moderate to fresh winds will prevail in the Papagayo region, pulsing to fresh to strong during the overnight hours through the rest of the week and into the weekend. Gentle to moderate winds will prevail elsewhere. Moderate southerly swell will subside tonight, with another set arriving Fri, and then a larger, reinforcing set this weekend. REMAINDER OF THE AREA... The remnant low pressure of Andres is located SSW of the Revillagigedo Islands near 15N114W and is moving west-northwest at 5-10 kt. Associated winds are 20 kt with seas to 7 ft. This remnant low is expected to dissipate later this morning. Elsewhere, a broad ridge covers the waters north of the ITCZ. Gentle to moderate trades, locally fresh, dominate the waters north of the ITCZ. Gentle to moderate winds prevail elsewhere. Northerly swell producing seas of 6-7 ft continues to propagate across the northern waters north of 25N between 125W and 135W. Seas are reaching 8 ft west of 135W and south of 12N and along the equator between 110W to 140W. Elsewhere, seas are in the 6-7 ft in a mix of mainly long period southerly and northerly swell. For the forecast, fairly tranquil marine conditions with moderate trades will prevail through the remainder of the week and weekend, along with mainly 5-7 ft seas. Southerly swell crossing the equator will help to maintain seas to 8 ft across the southern waters through midweek with a reinforcing set of southerly swell arriving east of 120W this weekend which will build seas to 7-9 ft south of 10N and east of 120W. $$ AReinhart/Lewitsky
