000 AXPZ20 KNHC 081547 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC WED JUN 08 2016 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 1430 UTC. ...SPECIAL FEATURE... The remnants of Tropical Depression One-E are near 16.4N 94.8W at 1500 UTC, moving N or 360 degrees, 03 knots. The estimated minimum surface pressure is 1008 mb. The maximum sustained wind speeds are 20 knots with gusts to 30 knots. The sea heights across this area of winds are estimated to range from 6 to 8 feet. Convective precipitation: scattered to numerous strong within 300 nm of the center in the southeastern quadrant. Scattered strong from 240 nm to 330 nm away from the center in the southwestern quadrant. Active convective precipitation will continue to affect parts of southeastern Mexico from Chiapas, Mexico to Guatemala, in Belize and in Honduras. The possibility continues today for areas of localized flooding, especially across elevated terrain where landslides may occur also, due to the recent heavy rains that have been occurring across portions of this region. The depression is forecast to continue to weaken as it drifts northward and loses its tropical characteristics this afternoon, and then dissipates along the coast or just inland across the Gulf of Tehuantepec. The winds and seas in the Gulf of Tehuantepec will diminish gradually today. Please refer to the latest NHC public advisory under Awips/WMO headers MIATCPEP1/WTPZ31 KNHC, and the full forecast advisory under Awips/WMO headers MIATCMEP1/WTPZ21 KNHC for additional details. ..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N111W to 10N115W to 1011 mb low pressure center that is near 12N128W, to a second 1011 mb low pressure center that is near 12N134W. The ITCZ continues from 10n136w beyond 08N140W. Convective precipitation: Scattered moderate to isolated strong within 150 nm on either side of the line from 06N77W to 06N84W to 12N90W, within 60 nm to 150 nm to the south of the monsoon trough between 112W and 116W, within 150 nm to 300 nm to the south of the monsoon trough between 124W and 134W, and within 150 nm to the north of the monsoon trough between 129W and 135W. surface trough along 14N107W TO 11N108W TO 08N109W. Convective precipitation: scattered moderate to isolated strong from 07N to 13N between 105W and 111W. ...DISCUSSION... A surface ridge extends from a 1018 mb high pressure center, that is near 27N131W, to 20N125W and 17N117w. The surface pressure gradient, that exists between the area of high pressure and one 1011 mb surface low pressure center that is near 12N128W and another 1011 mb low center that is near 12N134W, is supporting fresh winds in the N semicircle of the areas of low pressure. The 12N134W low center will weaken first. The 12N128W low center is forecast to continue for the next 24 hours or so, with winds and seas expected to diminish gradually to 15-20 kt and 5-7 ft by Wednesday night. The surface pressure gradient that exists between the area of high pressure and lower pressure in the monsoon trough and in the vicinity of the ITCZ is supporting moderate to locally fresh trades S of 20N and W of 120W and seas in the 4-6 ft range. The surface pressure gradient that exists between the ridge and lower pressure that is present in the Gulf of California is supporting moderate to fresh NW winds off the coast of Baja California with seas in the 4-6 ft range. Fresh southerly winds prevail inside the Gulf of California and are expected to increase to about 20 kt during the next few afternoons through evenings along prominent coastlines due to daytime heating. SW monsoon flow prevails to the E of 100W with light to moderate winds prevailing outside the influence of TD One-E. Active weather is expected to continue n of 10N and e of 100W during the next few days as this moist sw flow persists. $$ MT
