152 AXPZ20 KNHC 140830 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed Dec 14 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 0600 UTC surface analysis and satellite imagery through 0830 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N83W to 06N94W to 06N104W. The ITCZ continues from 06N104W to 07N124W. It resumes from 09N135W to 09N140W. Scattered moderate to strong convection is noted from 08N to 18N between 122W and 132W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pressure ridge extends SE across the region to the offshore waters west of the Baja California peninsula to off Cabo Corrientes. The pressure gradient between this are of high pressure and lower pressure over Mexico is supporting moderate winds offshore the Baja California peninsula southward to off Cabo Corrientes. The pressure gradient is also supporting gentle to moderate winds over the Gulf of California. Light to gentle winds prevail elsewhere. Seas are in the 8-10 ft range offshore the Baja California peninsula in decaying NW swell. Seas over the Gulf of California are in the 2-4 ft range. Seas of 3-6 ft are noted elsewhere. For the forecast, high pressure extends SE across the offshore waters west of the Baja California peninsula extending Se to near Cabo Corrientes. NW swell over the waters off the Baja California peninsula will subside today. Fresh to strong northerly winds will develop across the Gulf of California late today and persist through Sat. Fresh gap winds will develop across the Gulf of Tehuantepec by the end of the week and strengthen Sat. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh offshore gap winds and seas of 4-5 ft prevail across the Gulf of Papagayo region. Gentle to moderate northerly winds are in the Gulf of Panama. Light to gentle winds are noted elsewhere across the remaining waters. Outside of the Papagayo region, seas are in the 3-4 ft range. For the forecast, moderate to fresh offshore gap winds will prevail in the Papagayo region throughout the week. Gentle to moderate northerly winds will prevail in the Gulf of Panama. Light to gentle winds are expected elsewhere. Slight seas can be expected across most of the offshore waters during the next several days. REMAINDER OF THE AREA... High pressure prevails across the waters north of 15N. The pressure gradient between the associated surface ridge and lower pressure in the vicinity of the ITCZ is supporting fresh to locally strong winds north of the ITCZ to near 20N and west of 125W. An upper level trough W of 140W is maintaining unstable atmospheric conditions, supporting scattered moderate to strong convection from 08N to 18N between 122W and 132W. Light to gentle winds are found elsewhere north of 20N. Gentle to moderate trade winds are elsewhere north of the ITCZ E of 125W. Gentle to moderate winds prevail south of the ITCZ. Seas of 7-10 ft in mixed prevail north of 12N and W of 110W, with seas in the 5-8 ft range elsewhere. For the forecast, areal coverage of the fresh to strong winds will decrease today, and shift east of 130W. Active weather will continue in the vicinity of these strong winds as the upper level trough persist just W of 140W. Seas will subside today. A new front will enter the far NW waters today than stall and weaken through Thu. This front will usher in another pulse of large NW swell. $$ AL
