000 AXPZ20 KNHC 030857 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0850 UTC Sat Aug 3 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 0850 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 90W N of 04N, moving W around 15 kt. Scattered moderate isolated strong convection was noted from 06N to 15N between 87W and 95W. The axis of a tropical wave is near 120W from 05N to 17N, moving W around 15 kt. A 1009 mb low pressure area is along the wave axis near 14N120W. Scattered moderate and isolated strong convection is within 150 nm NE quadrant of the low. Overnight scatterometer pass indicates near gale force winds within 120 nm E semicircle of the low. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 09N85W to 09N105W. The ITCZ extends from 10N121W to 09N129W to 09N135W. Scattered moderate and isolated strong convection is noted N of 02N E of 80W. Scattered moderate isolated strong convection was noted within 120 nm S of the monsoon trough between 81W and 85W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure ridging will dominate the waters west of Baja California through early next week. Southerly swell will propagate in to the waters S of 20N early next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh NE winds will prevail N of the monsoon trough, while gentle to moderate S to SW winds will prevail S of the trough. Southerly swell will propagate into the waters between the coast of Ecuador and the Galapagos Islands Sun, and continue to spread northward through early next week. REMAINDER OF THE AREA... Tropical Storm Flossie has moved W of the area into the Central Pacific basin and is centered near 18.3N 142.3W at 03/0900 UTC moving WNW at 15 kt. Estimated minimum central pressure is 998 mb. Maximum sustained wind speed is 50 kt with gusts to 60 kt. Scattered moderate isolated strong convection associated to Flossie is noted over the forecast waters from 18N to 21N between 136W and 140W. Flossie will continue to shift away from the area, and its impacts on the forecast area will decrease. By Sunday morning, any impacts from Flossie over the forecast waters will fall below advisory criteria, with winds diminishing to 20 kt or less and seas subsiding below 8 ft. Elsewhere, an area of southerly swell will propagate northward, reaching the equator this weekend, then reaching to near 10N early next week, assisted by freshening southerly winds S of the monsoon trough. $$ AL
