000 AXPZ20 KNHC 300401 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 401 UTC Thu Jul 30 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 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 0300 UTC. ...TROPICAL WAVES... A tropical wave entering the eastern Pacific is along 80W from near Ecuador through central Panama into the southwest Caribbean, moving 10 to 15 kt. No significant convection is noted near this wave. A tropical wave is N of 04N with axis near 92W, moving west at 10 to 15 kt. Scattered moderate convection is over the Gulf of Tehuantepec ahead of the wave, north of 14N between 94W and 96W. A tropical wave extends from 03N to 17N with axis near 101W, moving west at 10 kt. Scattered moderate convection is from 09N to 11N between 100W and 103W. A tropical wave extends from 04N to 17N with axis near 121W, moving west at 10 to 15 kt. A 1011 mb low pressure accompanies this wave near 13N121W. Scattered moderate to isolated strong convection is noted from 08N to 15N between 119W and 123W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N79W to 09N95W to 16N105W to 10N130W to 10N140W. Scattered moderate to isolated strong convection is observed within 90 nm either side of the monsoon trough between 110W and 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure west of Baja California will support moderate to locally fresh NW winds mainly north of Punta Eugenia through Fri night. A surface trough will prevail along the Baja Peninsula and will support moderate to locally fresh southerly winds over the northern Gulf of California through Fri night. These winds will increase to fresh to strong as the area of low pressure deepens. Farther south, pulses of fresh to strong gap winds are possible in the Gulf of Tehuantepec region Fri night through Sun night. These winds will support seas up to 6 ft, mixing with a component of longer period southerly swell. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... The monsoon trough has reformed along roughly 09N east of 100W. This will allow increased showers and thunderstorms off Panama and Costa Rica over the next couple of day, especially as weak tropical waves migrate westward across the area. This pattern will maintain gentle to moderate southerly breezes south of the trough, and mostly light and variable winds north of the trough. The exception will be pulses of fresh offshore winds are likely in the Papagayo region through Fri. REMAINDER OF THE AREA... A ridge of high pressure extends over the waters north of 16N. The pressure gradient between the ridge and the monsoon trough is supporting moderate NE trade winds north of the monsoon trough west of 115W. Seas in this region range between 5 to 7 ft. Meanwhile, cross-equatorial southerly swell east of 125W will support seas of 5 to 7 feet through the week. $$ Christensen
