000 AXPZ20 KNHC 241550 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1402 UTC Wed Jul 24 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 1510 UTC. ...SPECIAL FEATURE... Tropical Depression Dalila centered near 20.5N 119.0W at 24/1500 UTC moving NW at 6 kt. Estimated minimum central pressure is 1007 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Scattered moderate isolated strong convection is present in the SE semicircle within 120 nm of the center. Dalila will move to 21.1N 119.7W this evening, become a remnant low and move to 21.9N 120.8W Thu morning, 22.3N 122.1W Thu evening, 22.7N 123.5W Fri morning, and dissipate Sat morning. See the latest NHC forecast/advisory under AWIPS/WMO headers MIATCMEP5/WTPZ25 KNHC for more details. ...TROPICAL WAVES... A tropical wave has an axis extending from 03N84W to 19N83W, moving W around 20 kt. This wave is embedded in an area of scattered moderate and isolated strong convection in the vicinity of the monsoon trough N of 04N between 77W and 91W. A tropical wave has an axis extending from 03N98W to 15N99W, moving W between 15 and 20 kt. Only isolated showers are noted within 60 nm of the wave axis from 10N and 12N. A tropical wave has an axis extending from 02N110W to 18N108W, moving W around 15 kt. This wave is situated along the eastern edge of an area of convection associated with the monsoon trough from 06N to 14N between 110W and 118W. Scattered moderate and isolated strong convection is also observed lagging the wave axis from 16N to 19N between 104W and 107W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N75W to 10N81W to 09N89W to 11N100W to 10N114W, then continues SW of Dalila from 14N120W to 10N133W. Aside from convection associated with tropical waves and Dalila, Scattered moderate and isolated strong convection is noted N of 04N between 77W and 91W, from 09N to 12N between 101W and 104W and from 06N to 14N between 110W and 118W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak ridge will dominate the offshore forecast waters west of Baja California through Fri. A surface trough over the Baja Peninsula will support light to gentle southerly winds across the Gulf of California during the next several days. Northerly winds will increase to fresh to strong speeds over the Gulf of Tehuantepec region by Thu night. This gap wind event is expected to persist through early next week. Winds will generally be strongest when nocturnal drainage occurs. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh S to SW winds south of the monsoon trough will generally maintain seas to 7 ft off the coasts of Panama and Colombia through Fri. Seas of 8 to 9 ft are expected near the equator through Fri night as long period SE to S swell moves into the region. Fresh to strong gap winds will affect the Gulf of Papagayo Thu through Fri night in the wake of a passing tropical wave. Another gap wind event could begin in this area Sat night. REMAINDER OF THE AREA... A ridge dominates most of the forecast waters N of 15N and W of 120W. Recent scatterometer and altimeter data indicate moderate to fresh trade winds from 16N to 21N west of 130W with seas to 8 ft. Am area of mixed swell has caused seas W of a line from 00N131W to 06N131W to 10N133W to 17N138W to build to around 8 ft. The swell will decay and allow this area of seas to subside below 8 ft by Thu morning. $$ CAM
