000 AXPZ20 KNHC 282003 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1942 UTC Mon Oct 28 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 1800 UTC surface analysis and satellite imagery through 1900 UTC. ...SPECIAL FEATURES... ...GALE WARNING... Gulf of California/Sea of Cortez: Fresh to strong NW winds over the northern Gulf will diminish tonight as the pressure gradient relaxes. A tight pressure gradient will develop across the region again by early Wed with strong to minimal gale force northwest winds expected to develop over the northern Gulf in the wake of a strong cold front that will sweep southward across the southwestern U.S. and the far NW section of Mexico. Fresh to strong northerly winds are forecast to spread across the entire basin by Thu, and likely continue into early Fri before diminishing to mainly fresh speeds thereafter. ...TROPICAL WAVES... A tropical wave axis is along 103W from 08N to 16N, moving W at around 5 kt. Numerous moderate and scattered strong convection is noted from from 08N to 15N between 98W and 109W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 12N95W to low pressure near 12N103W to low pressure near 11N115W to low pressure near 12N134W to beyond 13N140W. Scattered moderate convection is occurring from 08N to 12N between 92W and 96W and from 11N to 15N between 130W and 135W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of California/Sea of Cortez: See the Special Features section for details on a gale warning for the northern portion of the gulf. Gulf of Tehuantepec: Model guidance continues to strongly suggest that another gale force northerly gap wind event will develop in the Gulf of Tehuantepec Thu night through at least Mon, with winds at least up to 40 kt Fri. Otherwise, a very broad and weak pressure pattern will prevail to the W of Baja California with mainly gentle to moderate NW-N winds through the middle of the week, along with wave heights mainly in the 4-7 ft range. By late Wed into early Thu, the fresh to strong winds described in the Gulf of California/Sea of Cortez section are forecast to seep through the Baja California Norte passages and across the waters N of Punta Eugenia, with seas building to near 8 ft as well. These winds will then diminish by Thu night. High pressure ridging will then prevail from NW to SE for the remainder of the week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds are expected across the offshore waters of Guatemala and El Salvador. Gentle to moderate S-SW monsoonal flow, occasionally pulsing to moderate to fresh speeds, will continue across the offshore forecast waters of Costa Rica, Panama, Colombia and Ecuador through the week. Wave heights are expected to be in the 4-7 ft range across the offshore waters, building to 6-9 ft W of 93W Fri and Fri night due to the possible gale event in the nearby Gulf of Tehuantepec. REMAINDER OF THE AREA... A set of fresh northerly swell with seas of 8-10 ft continues to propagate southward with the edge of 8 ft or greater currently along 26N. The seas will reach across the waters N of 24N and W of about 125W by tonight, then reach the waters N of 15N and W of 130W by Tue afternoon, then gradually decay thereafter. A few weak low pressure areas are embedded within the monsoon trough with any associated convection described above. Associated winds and seas are forecast to remain below advisory conditions with all of these lows. $$ KONARIK
