000 AXPZ20 KNHC 060958 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed Nov 6 2019 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 86W north of 05N, moving west at 10 kt. Associated convection is occurring primarily well E of the wave across the SW Caribbean. A tropical wave is along 105W, moving west at 15 kt. Scattered moderate isolated strong convection associated with the wave is within 90 nm either side of the ITCZ between 102W and 109W. A tropical wave is along 118W-119W from 05N to 18N, moving west at 5 to 10 kt. This wave is accompanied by a broad zone of moisture and active convection, with scattered moderate to strong convection noted from 10N to 20N between 114W and 124W. Active convection is expected to continue through Thu. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09.5N74W to 09.5N85W TO 07N94W. The ITCZ extends from 07N95W to 07.5N106W 07N118W, then resumes from 08.5N131W to 07.5N140W. Scattered moderate isolated strong convection was noted from 03N TO 08N E OF 83W, and within 90 nm either side of ITCZ between 91W and 109W, and between 121W and 132W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak pressure gradient across the Pacific waters will continue to support gentle to locally moderate N winds across the northern offshore waters and the Gulf of California through at least Sun. High pressure over the Gulf of Mexico will promote strong N gap winds across the Gulf of Tehuantepec tonight through Thu, pulsing to just below gale each night. The next strong cold front expected across the western Gulf of Mexico on Fri will induce another round of gale force winds across Tehuantepec late Fri through Sat night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Strong high pressure north of the Caribbean waters during the week will support fresh offshore winds across the Papagayo region throughout the week, pulsing to strong winds each night. Farther south, gentle to moderate S-SW monsoonal flow will continue across the offshore forecast waters of Costa Rica, Panama, Colombia, and Ecuador through the upcoming weekend. No significant long-period swell will affect the area for at least the next several days. REMAINDER OF THE AREA... A surface ridge extends from high pres centered near 37N135W southeastward to near the Revillagigedo Islands. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh NE trade north of the ITCZ to 22N and W of 116W. South of the ITCZ, gentle to moderate SE winds prevail. A tropical wave is along 118W-119W from 05N to 18N. A broad low or trough in association with the wave is expected to produce locally strong E to SE winds and seas around 8 ft across NE portions of this wave as the system moves slowly westward during the next couple of days. No cold fronts are expected to reach the area through Sat. Combined seas up to 9 ft in mixed swell will prevail from generally 10N to 20N west of 130W overnight and then shift to west of 135W Thu through Thu night. No other significant long-period swell is expected to impact the area through at least Sun night. $$ Stripling
