000 AXPZ20 KNHC 312154 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2113 UTC Wed May 31 2017 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 1800 UTC surface analysis and satellite imagery through 2115 UTC. ...SPECIAL FEATURES... Tropical Depression Two-E is centered 13.9N 97.6W at 31/2100 UTC or about 125 nm SSE of Puerto Angel Mexico and about 225 nm SE of Acapulco Mexico moving NE at 2 kt. Estimated minimum central pressure is 1006 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Scattered to numerous moderate and isolated strong convection is from 09N to 18N between 93W and 101W. See latest NHC Forecast/Advisory under AWIPS/WMO headers MIATCMEP2/ WTPZ22 KNHC for more details. ...TROPICAL WAVES... Tropical wave extends from 02N77W to 09N77W moving W at 10 to 15 kt. The wave coincides with broad 700 mb troughing between 75W and 81W and an 850 mb relative vorticity maximum in the vicinity of 07N79W. These dynamics are generating scattered to numerous moderate convection from 03N to 08N between 75W and 82W. Tropical wave extends from 05N87W to 13N87W moving W at 10 to 15 kt. The wave coincides with subtle 700 mb troughing between 85W and 89W...however any leftover energy from this wave will likely be absorbed by Tropical Depression Two-E to the west within 24 to 36 hours. Widely scattered moderate convection is from 06N to 11N between 86W and 90W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The Monsoon Trough extends from 12N102W to 10N120W. The ITCZ extends from 10N120W to 07N140W. Widely scattered moderate convection is from 08N to 12N between 101W and 111W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds will persist W of the Baja Peninsula through Friday. Stronger NW winds off the coast of southern California will enhance northerly swell that will spread southward and generate seas 7 to 8 ft N of 29N between 118W and 122W through this evening...then decay to 6 to 7 ft through Thursday afternoon. Gentle to moderate southerly winds are expected across the Gulf of California tonight into Thursday. Seas of 1 to 3 ft are expected...except for 3 to 4 ft across the entrance region to the Gulf of California. Mainly light to gentle winds and 5 to 7 ft seas will continue S of Baja California. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moist southerly flow associated with the Monsoon Trough will continue to support scattered showers and tstms mainly N of 04N. Some of this activity may contain strong gusty winds and produce rough seas. Light to gentle winds will prevail N of the trough axis with 4 to 6 ft seas. Mainly moderate S to SW winds are expected S of the trough axis with seas of 5 to 7 ft. REMAINDER OF THE AREA... Broad high pressure covers the area N of 15N W of 115W. The pressure gradient between this ridge and lower pressure associated with the convergence zone is supporting fresh NE trades from 09N to 15N W of 136W...with seas of 7 to 8 ft in mixed NE and SE swell. This area will generally remain a narrow region N of the ITCZ axis W of 130W through Saturday until the ridge weakens and retreats westward thereafter. Gentle to moderate trade winds will continue across the remainder of the forecast waters through tonight with 5 to 6 ft seas. $$ HUFFMAN
