000 AXPZ20 KNHC 062015 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2015 UTC Mon Apr 6 2020 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 1800 UTC surface analysis and satellite imagery through 2000 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 07N81W to 05N90W. The ITCZ continues from 05N90W to 04N105W and again from 05N109W to 06N124W to beyond 05N140W. Scattered moderate isolated strong convection is noted from 03N to 07N from 84W to 114W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak surface ridge axis extends SE to the W of Mexican offshore waters today, keeping benign marine conditions in place across most of the area. Some moderate NW winds are occurring offshore Baja California Sur, and moderate SW winds are ongoing ahead of a weak cold front in the northern Gulf of California. The cold front is located from 31N118W to 29N121W. Behind the front seas are 4 to 6 ft, otherwise seas are generally 3 to 5 ft or less across the area. The aforementioned cold front will approach Baja California Norte tonight, enter the northern Gulf of California Tue, then dissipate Tue night into Wed. Fresh to locally strong SW winds will pulse across the northern Gulf of California ahead of the front tonight and Tue night, while winds off of Baja California Norte gradually shift W to SW. High pressure will build in the wake of the front midweek. As the ridge builds in, fresh to locally strong winds are likely to develop off the west coast of Baja California Sur and offshore Cabo Corrientes Wed and Thu. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds envelope most of the waters today, with seas less than 5 ft except for 5 to 7 ft seas between the Galapagos Islands and mainland Ecuador where SW swell is propagating into the area. As high pressure centered in the western Caribbean strengthens into late week, fresh to strong NE winds will pulse each night in the Gulf of Papagayo region, starting tonight. Long-period SW swell prevailing across the southern waters will subside through midweek. REMAINDER OF THE AREA... A cold front is moving across the far northern waters. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ is supporting mainly gentle to moderate tradewinds N of the ITCZ to 22N and W of 120W, where seas of 5-7 ft prevail. The cold front will continue to move slowly ESE across the waters N of 25N through Tue night, while a weak ridge will prevail S and W of the front. This setup will support gentle to moderate winds, and seas in the 4-7 ft range over the forecast waters N of the ITCZ through Tue. Fresh trade winds will return late Tue through mid week as high pressure builds in the wake of the front. $$ KONARIK
