000 AXPZ20 KNHC 070927 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sun Feb 7 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 0600 UTC surface analysis and satellite imagery through 0915 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 convection is within 60 nm north of the ITCZ between 135W-136W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Surface ridging prevails across the forecast waters west of Baja California. Overnight ASCAT data showed 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 tonight through early Tue, then mainly fresh winds through Thu night. Fresh north winds through the Gulf of Panama will begin tonight and continue through early on Wed, then diminish to moderate speeds through Thu night. Light to gentle winds are expected elsewhere during the period. REMAINDER OF THE AREA... Northwest swell is resulting in wave heights of 6-8 ft over the northern waters north of 28N between 121W-127W. This swell will decay through this afternoon 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 tonight. This will cause for the pressure gradient north of the ITCZ to weaken, however, a tight pressure 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 slowly subside through the early part of the week as they shift west of 140W. Otherwise, rather benign marine conditions are expected to continue across the rest of the discussion area through the forecast period. $$ Aguirre
