000 AXPZ20 KNHC 180316 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Jan 18 2022 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 0230 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from NW Colombia to 04N79W to 04.5N83W. The ITCZ continues from 04.5N86W to 04.5N96W to 10N135W. Scattered moderate convection is noted from 04.5N to 08N between 78W and 80W, from 08N to 12.5N between 118W and 130W, and from 12.5N to 19N between 126W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Strong N to NE winds, and seas of 7-8 ft prevail across the Gulf of Tehuantepec, and extend downwind to near 14.5N. A weak pressure gradient across the remainder of the area is supporting mainly light to gentle winds across the offshore waters from Baja California Norte to Puerto Angel. Seas are in the 1-3 ft range over the Gulf of California, and 5-7 ft over the remainder of the open waters off Mexico. For the forecast, fresh to strong winds will prevail over the Gulf of Tehuantepec through Tue night before diminishing moderate to fresh through Thu afternoon. Gale-force winds are possible over the Tehuantepec region once again the end of the week. W-NW swell will continue to move through the waters offshore of Baja California through Wed. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to strong NE to E gap winds prevail across the Gulf of Papagayo, where seas are 5 to 7 ft downwind. Moderate to locally fresh N-NE winds are over the Gulf of Panama. Light winds prevail north of a surface trough stretching across the Central American offshores with gentle winds south of it. Seas are 4-6 ft outside of the Gulf of Papagayo, mainly due to S to SW swell. For the forecast, fresh to strong gap winds will prevail across the Papagayo region through most of the week, with fresh winds extending beyond 90W late tonight through Tue morning. Northerly winds across the Gulf of Panama will pulse to fresh through Wed night. A surface trough will extend across the Central American offshores with light to gentle winds north of it and gentle winds south of it. REMAINDER OF THE AREA Subsiding west to northwest swell continues across the waters west of 90W, with seas in the 6-8 ft range. A broad surface trough extends from a 1016 mb surface low near 31.5N121W to 21N125W. Light to gentle winds are found within 250 nm either side of the trough. High pressure NW of the trough is supporting gentle to moderate N to NE winds W of the trough to 10N. Expect mostly gentle north to northeast winds to persist west of the surface trough as it drifts westward and weakens through Tue. Small to moderate W-NW swell will continue to move through the waters W of 110W through the end of the week. The surface trough is forecast to drift W through Tue, with weak low pressure just N of the area. This will maintain a weak pressure gradient across the regional waters and fairly tranquil marine conditions. A new surface trough is expected to develop north of the ITCZ near 130W-132W on Tue and drift northward through mid week. Increasing winds and seas will be seen near and north of the trough during this time as the pressure gradient tightens. There is the potential for winds to reach minimal gale force by early Thu from 20N to 25N with, seas 10 ft and higher. $$ Stripling
