000 AXPZ20 KNHC 261501 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1500 UTC Fri Jul 26 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 84W N of 03N, moving W at 15 kt. Scattered moderate isolated strong convection is noted from 04N to 10N between 81W and 87W. The axis of a tropical wave is near 94W N of 03N, moving W at 15 kt. Scattered moderate isolated strong convection is noted from 05N to 15N between 93W and 98W. This wave will be one to watch with interest over the next several days for possible tropical cyclone development. Although there is a low chance for development over the next couple of days, there is a medium probability for tropical cyclone formation afterwards. Please see the latest eastern North Pacific Tropical Weather Outlook for more information. The axis of a tropical wave is near 111W from 04N to 17N, moving W at 15 kt. Scattered moderate convection is noted from 08N to 11N between 109W and 113W. The axis of a tropical wave is near 118W from 02N to 16N, moving W at 10 to 15 kt. Scattered moderate isolated strong convection was noted from 07N to 13N between 113W and 122W. This wave will be one to watch with interest over the next several days for tropical cyclone development. The wave is currently producing a broad area of disorganized showers and there is a low probability for tropical cyclogenesis within the next 48 hours. However, environmental conditions are expected to become more conducive for tropical cyclone development, and a tropical depression could develop early next week. Please see the latest eastern North Pacific Tropical Weather Outlook for more information. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 07N78W to 07N82W to 12N111W to 06N125W. The ITCZ continues from 06N125W to 05N131W to 09N140W. Scattered moderate isolated strong convection was noted N of 05N E of 81W. Scattered moderate isolated strong convection is noted from 08N to 12N between 98W and 108W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak ridge will dominate the forecast waters west of Baja California through Tue, with gentle to moderate winds prevailing. Fresh to strong gap winds will prevail across the Gulf of Tehuantepec through the weekend before diminishing. Winds will then pulse to fresh to strong Mon night and Tue night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong gap winds will prevail across the Gulf of Papagayo through Tue, with seas in the 7-9 ft range. Gentle to moderate NE to E winds will prevail elsewhere N of the monsoon trough. Gentle to moderate S to SW winds will prevail south of the monsoon trough. REMAINDER OF THE AREA... The remnant low of Dalila is evident on satellite imagery as a swirl of low level clouds near near 23N123.5W. Dalila is forecast to weaken into a trough by tonight. A ridge dominates the forecast waters N of 25N. The pressure gradient between the area of high pressure and lower pressure in the monsoon trough and in the vicinity of the ITCZ is fairly weak. This is resulting in mainly gentle to moderate winds north of the ITCZ/monsoon trough. The ridge will strengthen slightly across the northern forecast waters this weekend as the remnant low of Dalila dissipates, bringing a moderate increase in winds N of the ITCZ/monsoon trough. Moderate to fresh winds prevail S of the ITCZ/monsoon trough. This is helping for seas in the 6-8 ft range across this area. There are two tropical waves which are being monitored for the potential for tropical cyclogenesis, and are discussed in the tropical wave section above. $$ AL
