000 AXPZ20 KNHC 140231 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Dec 13 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... The monsoon trough extends from 09N83W to 06N94W to 06N104W. The ITCZ continues from 06N104W to 09N127W to 09N140W. Scattered moderate isolated strong convection is noted from 08N to 12N between 126W and 134W. 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 8-11 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. NW swell over the waters off the Baja California peninsula will gradually subside through midweek. Fresh to strong northerly winds will develop across the Gulf of California late Wed and persist through Sat. Fresh gap winds will develop across the Gulf of Tehuantepec by the end of the week and strengthen Sat. y the end of the week and strengthen to strong 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 4-6 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 21N and west of 125W. An upper level trough W of 140W is maintaining unstable atmospheric conditions to its east, supporting scattered moderate and isolated strong convection from 08N to 12N between 126W and 134W. Seas are 9 to 11 ft across this area. Seas of 8-11 ft in NNW swell prevail north 25N and E of 130W. Light to gentle winds are found elsewhere north of 22N. Gentle to moderate trade winds are elsewhere north of the ITCZ E of 125W. Gentle to moderate winds prevail south of the ITCZ. Seas are in the 5-8 ft range elsewhere. For the forecast, areal coverage of the fresh to strong winds will gradually decrease through Wed, and shift east of 130W. Active weather will also continue in the vicinity of these strong winds as the upper level trough persist just W of 140W. Seas will gradually subside through mid week. A new front will enter the far NW waters Wed than stall and weaken through Thu, accompanied by another pulse of large NW swell. $$ AL
