000 AXPZ20 KNHC 070402 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sun Feb 07 2021 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 0345 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 05N82W to 04N95W, where latest scatterometer data indicates that it transitions to the ITCZ to 05N110W to 04N120W to 04N130W and to beyond 05N140W. Scattered moderate to isolated strong is within 60 nm of the ITCZ between 134W and 138W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Surface ridging prevails across the forecast waters west of Baja California. Latest ASCAT data continues to depict gentle to moderate northerly winds west of Mexico, and altimeter data passes indicate seas generally in the 4-6 ft range. Fresh to strong gap winds are expected in the Gulf of Tehuantepec by early Sun through early Mon as high pressure builds southeastward across the Gulf of Mexico in the wake of a cold front, while gentle to moderate winds are expected elsewhere through late in the upcoming week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... A weak pressure pattern prevails across the Pacific region south of Central America. Latest scatterometer data continues to depict light to gentle winds in this area. Seas are generally 3-5 ft due to mixed southwest and northwest swell. High pressure over the northwest Caribbean Sea will maintain fresh to occasionally strong offshore winds across the Gulf of Papagayo Sun night through early Tue, then mainly fresh winds through Thu night. Fresh north winds through the Gulf of Panama will begin Sun night through early on Wed, then diminish to moderate speeds through Thu night. Light to gentle winds are expected elsewhere through the period. REMAINDER OF THE AREA... Northwest swell is resulting in wave heights of 7-9 ft over the northern waters north of 29N between 122W and 126W. This swell will decay through Sun evening allowing for these wave heights to lower to less than 8 ft. High pressure well to the north of the forecast area extends a ridge southeastward deep into the tropics south of 20N and west of Mexico. The high will retreat northward and weaken through Sun night. This will allow for the pressure gradient north of the ITCZ to weaken, however, a tight gradient between the ridging and a frontal system well to the west of the area will sustain fresh east winds from about 04N to 15N and west of 129W through late on Mon. Wave heights within this area of winds are in the 8-10 ft range. These wave heights will subside slightly late on Mon. Otherwise, rather benign marine conditions are expected to continue across the rest of the discussion area through the forecast period. $$ Aguirre
