000 AXPZ20 KNHC 261946 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2000 UTC Sun Jul 26 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 1800 UTC surface analysis and satellite imagery through 1900 UTC. ...TROPICAL WAVES... A tropical wave axis is along 87W from 03N into Costa Rica, moving W at 10 to 15 kt. Scattered moderate convection has developed from 06N to 12N between 81W and 91W. A tropical wave axis now is along 105W, from 02N to 17N. It is moving W at 15 kt. Numerous moderate to strong convection is noted from 08N to 12N between 98W and 107W. A tropical wave extends along 135W from 02N to 17N, moving W at 5 to 10 kt. Convection previously associated with this wave has diminished. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 10N84W to 11N113W to 07N134W. The Intertropical Convergence Zone axis extends from 07N134W to beyond 05N140W. Aside from what is noted in tropical waves section above, scattered moderate convection is observed from 05N to 14N between 109W and 128W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure west of Baja California will support moderate to locally fresh NW winds north of Cabo San Lazaro into late week. A deep layer trough moving into the southwest US will allow pressure to lower north of the region Tue. This pattern will support moderate to fresh winds over the northern Gulf of California Tue and Wed. Farther south, light breezes and southerly swell will persist through the period. Weak low pressure of 1011 mb has formed around 12N97W. This low is expected to remain weak and drift NW well south and west of the southern Mexican coast over the next several days. As it does, the monsoon trough will lift northward to off the coast of southern Mexico by Tue. This will support increased showers and thunderstorms, mainly at night. Looking ahead, pulses of fresh to locally strong gap winds are possible in the Gulf of Tehuantepec region Thu night through Sat night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR.. The monsoon trough is currently along roughly 10N, but will lift northward early in the week to a position parallel to the coast of Central America. This pattern will maintain scattered thunderstorms and gentle to moderate southerly winds. Pulses of fresh offshore winds are likely to occur in the Papagayo region Wed through Fri. REMAINDER OF THE AREA... A ridge of high pressure extends over the waters north of 20N. The pressure gradient between the ridge and the monsoon trough/ITCZ is supporting moderate NE trade winds north of the monsoon trough west of 120W with seas in the 5 to 7 ft range. Meanwhile, cross-equatorial southerly swell E of 115W will gradually decay into tonight, allowing seas to fall below 8 ft. $$ KONARIK
