000 AXPZ20 KNHC 130217 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 216 UTC Mon Feb 13 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. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The ITCZ remains south of the equator. A surface trough extends from 05N90W to 01N99W. No significant convection noted. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Baja California / Gulf of California: A dissipating cold front will move across the central and southern Gulf of California, followed by a deep layer trough moving into the Baja California peninsula. Fresh to strong northwest winds follow these features across the region, along with northwest swell off Baja California. Through tonight, the front will dissipate as it moves southeast and the trough will dampen out. The pressure gradient will relax through Monday as developing low pressure shifts east of the region, allowing winds to diminish. Seas off Baja California will subside as well as the northwest swell decays. Winds and seas diminish across the region through late Monday, leaving gentle to moderate breezes in place through mid week. Farther south, strong gap winds will briefly pulse into the Gulf of Tehuantepec late tonight. Light to gentle breezes will follow through mid week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Strong gap winds will pulse through the Gulf of Papagayo tonight and Monday night, but not as strong or long lasting as the past couple of days. Moderate to fresh gap winds will follow during overnight hours through mid week through the Gulf of Papagayo and the Gulf of Panama. Light to gentle winds and combined seas of 3-6 ft are occurring elsewhere outside the gap wind events with little change expected through mid week. REMAINDER OF THE AREA... Strong southerly winds and 8 ft seas over the northwest waters of the discussion area north of 28N and west of 135W will persist through Monday ahead of a pair of cold front currently west of the area. Southwest winds will increase and expand eastward into mid week accompanied by northwest swell to 18 ft pushing southwest of 30N140W by late Tuesday. Looking ahead, the cold front will enter the northwest area by Wednesday, but supporting upper dynamics will lift northeast of the area allowing the winds to diminish into Thursday. The large swell will decay as well but combined seas 10 to 14 ft will remain over the area north of 25N and west of 130W into Thu. South of 20N, areas of combined seas to 8 ft in mixed northeast wind waves and longer period northwest swell will persist with an influx of new northwest swell through mid week. $$ CHRISTENSEN
