000 AXPZ20 KNHC 171600 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1514 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 1200 UTC surface analysis and satellite imagery through 1530 UTC. ...TROPICAL WAVES... A tropical wave is along 103W, south of 17N, moving westward at 15 kt. Scattered moderate to strong convection is noted from 07.5N to 22N between 100W and 110W. A tropical wave is along 115W/116W, south of 17N, moving westward at 15 kt. Scattered moderate isolated strong convection is noted from 07N to 16N between 112W and 122W. A tropical wave is along 139W, south of 18N, moving westward at 10-15 kt. Scattered moderate to strong convection is noted from 08N to 15.5N west of 132W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N76W to 05N82W to 12N114W to 08N124W. The ITCZ continues from 08N124W to 12.5N138W 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 low pressure over Mexico and high pressure 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 fresh to strong gap winds in the Gulf of Tehuantepec region through Sun. Strongest winds are expected tonight. 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 gap winds will persist 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 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 weak frontal trough is moving over the waters north of 27N from 125W to 130W, ushering in N to NE winds of 15-20 kt and northerly swell in the range of 7-8 ft. This boundary will gradually dissipate while seas remain 7-8 ft into Sat. Global models continue to suggest the development of a low pressure area in association with the tropical wave, presently near 115W, in 2 to 3 days as it moves westward over open waters. $$ Stripling
