000 AXPZ20 KNHC 060212 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Aug 5 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 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 89W, moving W at 10-15 kt. Convection is limited with this wave. The axis of a tropical wave is near 105W, moving W around 10 kt. Convection is limited with this wave. The axis of a tropical wave is near 124W, moving W around 10 kt. Scattered moderate and isolated strong convection is noted from 11N to 16N between 120W and 126W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N84W to 09N115W to 12N128W, then resumes near 12N133W to 12N140W. Scattered moderate and isolated strong convection is noted from 05N to 09N east of 83W, from 06N to 09N between 90W and 99W, from 06N to 10N between 108W and 115W, and from 07N to 12N between 126W and 133W. Scattered moderate convection is noted from 11N to 13N between 96W and 101W, and from 11N to 13N between 135W and 139W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pressure ridge prevails across the forecast waters west of the Baja California peninsula, producing gentle to moderate NW flow over the adjacent offshore waters as supported by earlier ship and scatterometer observations. This ridge will prevail across the waters through the week and into the upcoming weekend, with little change in wind and sea conditions. Southerly swell will continue impacting the waters south of Cabo San Lazaro while gradually subsiding through mid week. Another set of long period southerly swell will reach the southern waters by Thu, but combined seas are expected to remain less than 8 ft through the forecast period. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gentle to moderate S to SW winds south of the monsoon trough are increasing to moderate to fresh through Thu, with seas building to 8 ft. Moderate to locally fresh NE to E winds will prevail north of the monsoon trough near the Gulf of Papagayo region for the next several days. Elsewhere, light to gentle breezes will prevail north of the trough. Seas will build greater than 8 ft between Ecuador and the Galapagos Islands Wed night through Sat night as a fresh set of long period, southerly swell propagates into the region. REMAINDER OF THE AREA... The remnant low of Gil is centered near 15.5N131W. Associated winds have diminished to 20 kt or less, with peak seas analyzed to 8 ft. Seas will subside below 8 ft later tonight. Elsewhere, high pressure prevails across the forecast waters north of 20N. Moderate to locally fresh NE winds prevail within the enhanced gradient between this ridge and the remnants of Gil. Otherwise, gentle to moderate winds continue across the high seas domain. Southerly swell remains across much of the region east of 125W. Seas of 8-9 ft prevail south of the equator to the west of the Galapagos Islands, as well as reaching north of the equator to 09N between 92W and 115W. This swell will propagate slightly more northward Tue while mixing with locally generated wind waves associated with a surge in the monsoon flow. Looking ahead, another set of long period southerly swell will propagate across the equator by mid week and spread northward across the area into the upcoming weekend. $$ Lewitsky/ERA
