000 AXPZ20 KNHC 011948 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1605 UTC Sat Aug 1 2020 Corrected ITZC/Monsoon Trough section 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 1200 UTC surface analysis and satellite imagery through 1530 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 95W/96W, north of 02N to the western Gulf of Tehuantepec region and over southeastern Mexico. It is moving westward at about 15 kt. Isolated showers and thunderstorms are along the wave axis from 10N to 12N. A tropical wave has its axis along 107W from 02N to 18N, moving westward at 15-20 kt. Scattered moderate to isolated strong convection is seen within 180 nm east of the wave from 14N to 18N. A tropical wave has its axis along 118W from 02N to 18N, moving westward at 15-20 kt. Scattered moderate to isolated strong convection is within 120 nm east of the wave from 14N to 17N. Scattered moderate convection is within 120 nm west of the wave from 10N to 14N. A tropical wave has its axis along 135W from 01N to 18N, moving westward at 15 kt. Isolated showers are near the wave axis. Scattered showers and isolated thunderstorms are within 120 nm either side of the wave axis from 09N to 12N. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...Corrected The monsoon trough axis extends from low pressure of 1010 mb over northwestern Colombia southwestward to 08N79W and northwestward to 10N87W, then to 08N98W to 12N107W to 12N117W to low pressure near 09N119W 1010 mb to 06N127W and northwestward to 08N135W to low pressure near 14N139W 1010 mb. Scattered moderate to strong convection is within 120 nm north of the trough between 99W-101W, also between 102W-107W, within 210 nm NW quadrant of low pressure near 09N119W and within 60 nm south of the trough between 105W- 107W. Scattered moderate to isolated strong convection is within 60 nm south of the trough between 82W-86W. Scattered convection moderate is within 180 nm south of the trough between 109W-115W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weakening pressure gradient between high pressure centered near 32N132W and an elongated trough that stretches from the southwestern U.S. into NW Mexico will support gentle to moderate northwest winds west of Baja California Norte, with 4-6 ft seas. Moderate to fresh southerly winds are expected in the northern Gulf of California well into the middle part of the upcoming week. Fresh northerly winds funneling in a narrow swath over the Gulf of Tehuantepec region, as were noted in an overnight ASCAT pass, will diminish to gentle speeds Sun afternoon and become light and variable by early Sun evening. These winds will again become fresh northerly winds Sun night and continue through early Wed afternoon, at which time they are expected to diminish to gentle speeds. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... A monsoon trough axis stretches along 09N to 10N east of 90W. Weak tropical waves will migrate westward across Central America early in the week, and initiate more widespread shower activity in a few days. Moderate southerly winds will prevail south of the monsoon trough through Wed. REMAINDER OF THE AREA... Weak high pressure ridging is over the waters north of 15N, with the parent weak high center of 1023 mb located at 32N133W. The gradient between the ridge and the monsoon trough is supporting moderate trade winds north of the trough axis, west of 115W. A shrinking area of cross-equatorial southeast swell, producing seas in the range of 7-9 ft seas, is located south of 15N and west of 130W. This area of swell will gradually shift west of 140W by early Sun. $$ Aguirre
