000 AXPZ20 KNHC 292116 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Thu Apr 29 2021 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from northern Colombia near 10N74W to 08N79W to 09N84W to 08N89W to 11N106W. The ITCZ extends from 07N117W to 03N125W to 05N140W. Scattered moderate and isolated strong convection is noted from 05N to 08N between 82W and 85W, from 05N to 09N between 96W and 107W, from 12N to 15N between 103W and 108W, and from 02N to 13N between 109W and 126W. Scattered moderate convection is noted from 05N to 12N between 86W and 96W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge of high pressure prevails west of the Baja California peninsula. The pressure gradient between this are of high pressure and low pressure over Mexico is supporting moderate to locally fresh winds off the Baja California peninsula as well as in the central and southern Gulf of California. Gentle to moderate winds prevail elsewhere over the open waters off Mexico, except locally fresh offshore of Oaxaca. Seas are in the 4-6 ft range in a mix of northwest and south swell over the open waters off Mexico. For the forecast, high pressure west of the region will support moderate to fresh winds off Baja California, locally strong in the central and southern Gulf of California through the end of the week. A set of northwest swell will build west of Baja California late in the upcoming weekend into early next week. Farther south, a moderate southerly swell will gradually subside through the upcoming weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate winds are noted in the Papagayo region. Light to gentle winds persist elsewhere. Seas are in the 4-6 ft range in lingering southerly swell, except 5-8 ft offshore of Ecuador. For the forecast, moderate winds will pulse in the Papagayo region into the upcoming weekend. Otherwise, light to gentle winds will persist across the region, increasing to gentle to moderate early next week. Moderate southerly swell will gradually decay through the end of the week. REMAINDER OF THE AREA... High pressure is centered north of the area with a ridge axis extending from 32N130W southeast to near the Revillagigedo Islands. The pressure gradient between the area of high pressure and lower pressure in the vicinity of the ITCZ is supporting mainly moderate winds north of the ITCZ, locally fresh, with seas in the 4-7 ft range, locally to 8 ft near 13N114W where a deep area of convection is persisting near a surface trough. Light to gentle winds and seas in the 5-7 ft range prevail elsewhere. High pressure will continue north of the area with these general conditions prevailing into the upcoming weekend. A set of northwest swell with building seas will propagate south of 30N between 120W and 140W late in the weekend into early next week. Conditions will improve into mid-week. $$ Lewitsky
