000 AXPZ20 KNHC 040227 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0130 UTC Sun Jun 4 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 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...TROPICAL WAVES... A tropical wave is southwest of the Gulf of Tehuantepec with axis extending from 15N96W to 03N95W, moving west at 15 kt within the last 24 hours. The wave coincides with a region of middle level diffluence that supports scattered moderate convection from 03N-10N between 90W-97W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 08N83W to 10N94W...then resumes west of a tropical wave near 10N98W and continue to 09N116W. The ITCZ begins near 09N116W and continues along 09N120W to 08N130W to beyond 07N140W. Heavy showers and tstms are from 05N to 08N between 80W and 84W...and within 150 NM either side of the ITCZ. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Persistent ridging over the area will continue to support gentle to moderate west to northwest winds through next Thursday, with periodically fresh to strong winds off Los Cabos, mainly at night due to local effects. Seas will remain generally 4 to 7 ft through Sunday night. Northwest to north swell will propagate into the waters off Baja California Norte beyond 200 nm starting early Monday afternoon through Tuesday evening. Surface troughing over the Baja Peninsula will maintain light to gentle winds over the Gulf of California through Monday night. Winds north of 29N will become moderate Tuesday through Thursday. Otherwise, little change in expected. 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 generate scattered to numerous showers and thunderstorms primarily N of 04N with possible locally strong gusty winds and rough seas. Light to gentle winds will prevail generally north of 10N with 4 to 6 ft seas. Moderate south to southwest winds are expected south of 10N with corresponding seas of 5 to 7 ft as cross-equatorial southwest swell augment combined seas. REMAINDER OF THE AREA... Broad surface high pressure anchored by a 1029 mb high NW of the area extends a ridge axis southeast to the Revillagigedo Islands, thus maintaining moderate to fresh trade winds north of the ITCZ axis to 16N W of 122W. The ridge will continue weakening as a dissipating cold front crosses the eastern Pacific north of the area. High pressure following in the wake of the front will provide a surge of moderate to fresh north winds and 5 to 7 ft seas into the region north of 28N between 118W and 125W Sunday and Monday, then the high will weaken and allow winds and seas to subside. Southwest swell crossing the equator currently supporting seas between 8 and 9 ft south of 0N between 106W and 120W and from 0N to 06N between 115W and 120W will gradually subside through late Monday night and allow seas in this area to subside to 4 to 6 ft. $$ RAMOS
