000 AXPZ20 KNHC 250913 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Wed May 25 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... The monsoon trough extends from the coast of NW Panama near 10N85W to 12N110W to 10N130W and to 07N140W and beyond. Scattered moderate to isolated strong convection is present from 04N to 15N and E of 123W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure located well to the northwest of the area maintains light to gentle NW winds over the waters west of the Baja Peninsula. The exception is a small area of moderate to locally fresh winds found offshore the Los Cabos region. Seas are 4-7 ft. Gentle to light winds are also noted in the Gulf of Tehuantepec, along with seas of 1-3 ft. Elsewhere in the Mexican offshore waters, light to gentle winds and 4-7 ft seas prevail. A surface trough located a few hundred miles south of the Gulf of Tehuantepec is producing disorganized showers and thunderstorms. This disturbance has a low probability for tropical cyclone development in the next 48 hours. Afterwards, environmental conditions will become more conducive for tropical cyclogenesis, and there is a high probability for tropical cyclone development within the next 5 days. This developing area of low pressure will bring an increase in winds and seas to southern Mexico starting late this week into the weekend. Elsewhere in the forecast, light to gentle winds west of the Baja California peninsula will increase toward the weekend as the pressure gradient tightens. Gentle to moderate winds will prevail through the rest of the week in the remainder of the area. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Recent satellite-derived data captured gentle to moderate S-SW winds south of the monsoon trough. However, stronger winds were noted near the areas of heavy showers and thunderstorms. Light to gentle winds were present north of the monsoon trough. Seas of 3-6 ft are occurring in these waters. For the forecast, light to occasionally moderate breezes will continue across the forecast waters through early next week. Seas will build to near 8 ft this morning well southwest of Nicaragua, before decreasing below 8 ft by Thu morning. ...REMAINDER OF THE AREA... The subtropical ridge well north of the area dominates the region, allowing for fairly tranquil weather conditions north of the deep tropics. A surface trough located along 110W is producing disorganized convection and a recent scatterometer satellite pass show moderate to fresh SW winds to the east of the trough axis. Seas of 6-9 ft are found from 04N to 13N and between 90W and 103W. Northerly swell is also producing seas up to 8 ft N of 24N and between 122W and 130W. The pressure gradient between the high pressure and the monsoon trough results in moderate to fresh winds N of the monsoon trough to 17N and W of 125W. Seas in the region are 5-8 ft. Elsewhere, moderate or weaker winds and seas of 4-6 ft prevail. There are a couple of disturbances within the monsoon trough that are being monitored for tropical cyclone potential, one near 94W is discussed in the section above. The other disturbance is near 110W. This perturbation has a low probability for tropical cyclone development. For the forecast, the moderate to fresh winds in the deep tropics are expected to diminish today, along with the seas. Elsewhere, winds and seas will decrease through the end of the week. High pressure will build again this weekend causing winds to increase. $$ Delgado
