000 AXPZ20 KNHC 170905 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 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 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...TROPICAL WAVES... A tropical wave is along 102W/103W, south of 17N, moving westward at 15 kt. Scattered moderate convection is noted from 08N to 17N between 101W and 109W. A tropical wave is along 113W/114W, south of 17N, moving westward at 10-15 kt. Scattered moderate isolated strong convection is noted from 07N to 15N between 112W and 120W. A tropical wave axis extends from 18N136W to 02N139W, moving westward at 10-15 kt. Scattered moderate to strong convection is noted from 07N to 12N between 135W and 140W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 08N78W in Panama to 10N86W to 08N91W to 11N97W to 10N107W to 13N110W to 08N120W. The ITCZ axis continues from 08N120W to 08N128 to 12N134W 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 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 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 trough is moving over the waters north of 25N from 125W to 130W, 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 114W, in 2 to 3 days as it moves westward over open ocean. $$ Mundell
