000 AXPZ20 KNHC 170300 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Fri Jul 17 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 is along 101W, south of 17N, moving westward at 10-15 kt. Scattered moderate isolated strong convection is noted from 08N to 14N between 95W and 107W. A tropical wave is along 112W, south of 17N, moving westward at 10-15 kt. Scattered moderate isolated strong convection is noted from 06N to 13N between 111W and 119W. A tropical wave axis extends from 18N135W to 02N137W, moving westward at 10-15 kt. Scattered moderate isolated strong convection is noted from 07N to 13N between 134W and 140W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 08N78W in Panama to 09N89W. The ITCZ axis continues from 09N89W to 10N100W, to 13n106W to 10N112W, to 08N117W to 11N133W to 11N136W, to 10N140W. Minimal convective activity is noted outside of that associated with tropical waves described above. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The gradient between lower pressure over Mexico and high pressure to the west of Baja California will support fresh NW winds west of Baja California into the weekend. High pressure building southward from the Gulf of Mexico will induce strong gap winds in the Gulf of Tehuantepec region through early Sun. Strongest winds are expected on Fri night. No significant long- period swell is expected in the Mexican offshore zones the next several days. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to occasionally strong northeast to east winds will continue in the Gulf of Papagayo region through early Sat. Moderate to fresh southwest winds will prevail over the waters south of 08N through Tue, with locally fresh winds possible this weekend. No significant long-period swell is expected in the Central American and equatorial offshore zones the next several days. REMAINDER OF THE AREA... A ridge across the northern waters extends from a high located well northwest of the area. The gradient between the high and lower pressures associated with the ITCZ is supporting moderate to fresh winds north of the convergence zone west of 120W. Seas are in the 5-7 ft range. Moderate to locally fresh southerly winds prevail south of the monsoon trough and ITCZ. Cross equatorial SE swell maintains seas in the 7-8 ft range south of 08N and west of 115W. A trough will move over the waters north of 25N from 125W to 130W late tonight, ushering in northerly swell in the range of 7- 9 ft into early Sat. Global models continue to suggest the development of a low pressure area in association with the tropical wave, presently near 112W, in a few days as it moves westward over open ocean. $$ Mundell
