000 AXPZ20 KNHC 252131 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Tue Jan 25 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 1800 UTC surface analysis and satellite imagery through 2030 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from Colombia near 04.5N77W southwest to 02.5N78W. A surface trough axis extends from Costa Rica near 09N84W to low pressure near 07.5N90W 1011 mb. The monsoon trough extends from 07.5N90W to 09N106W. A surface trough extends from 12N107W to low pres near 08N110W 1011 mb to low pres near 09N118W 1011 mb to 07N128W. The ITCZ continues from 07N128W to 08.5N140W. Scattered moderate convection is noted from 00N to 08N between 77W and 81W and from 06N to 10N between 105W and 119W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Latest ASCAT wind data shows light to gentle winds across most of the Mexico offshore waters, with moderate N winds observed offshore Cabo Corrientes. Moderate W winds are noted near the coast of Oaxaca. Seas are 6-8 ft offshore Baja California in WNW swell, 1-2 ft in the Gulf of California and 4-5 ft elsewhere. For the forecast, moderate northwest swell will continue west of Baja California through tonight before subsiding. Strong N winds are expected in the Gulf of Tehuantepec late tonight through Thu night. Then, gap winds to gale-force speeds are possible over the Gulf of Tehuantepec beginning Fri night as a strong cold front moves across the western Gulf of Mexico into southern Mexico. Marine conditions will deteriorate in the Gulf of Tehuantepec beginning Fri night and lasting through the upcoming weekend. Fresh to strong NW winds are likely in the Gulf of California late Thu night through Fri night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh east gap winds are occurring across the Papagayo region, while light to gentle variable winds along with seas of 4 to 6 ft are elsewhere, except for moderate to fresh N winds in the Gulf of Panama. For the forecast, the fresh northeast to east gap winds across the Papagayo region will pulse to strong Wed through Thu, then again late Sat through Mon. Pulsing moderate to fresh N winds will continue in the Gulf of Panama through Thu night, then return to the area Sat night. Over the remainder of area, winds should remain tranquil for the next several days. Large northwest swell from an upcoming Gulf of Tehuantepec gap-wind gale event will infiltrate the Guatemala and El Salvador offshore waters on Sat and Sat night building the seas there to around 10 to 14 ft. REMAINDER OF THE AREA A ridge extends across the northern waters, with mainly light to gentle winds north of 25N. A surface trough extends from 18N129W to 13N133W. Upper-level troughing is present between 130W-140W. Divergence aloft to the east of the upper-trough is enhancing scattered moderate isolated strong convection from 13.5N to 22N between 121W-136W. This activity is helping to maintain an area of moderate to locally fresh east winds over the waters from 19N-23N between 128W-140W. Northwest swell is producing significant wave heights of 7-9 ft over the waters from 05N to 30N and between 120W-140W. Wave heights are 5-6 ft elsewhere. For the forecast, the west to northwest swell will decrease in coverage over the next 24-30 hours while it subsides. Gentle to moderate winds will continue across the basin through Fri. A surface trough is likely to amplify over the weekend, bringing fresh to strong winds and building seas in the vicinity of 10N- 20N between 123W-133W. $$ Hagen
