000 AXPZ20 KNHC 260336 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sun Jan 26 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 0000 UTC surface analysis and satellite imagery through 0215 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 05N77W to 04N84W to 03N93W. The ITCZ begins near 03N93W to 06N120W to 07N140W. Isolated moderate convection is from 06N to 12N between 111W and 128W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Long period NW swell will continue to propagate SE across the Baja California peninsula offshore waters with seas to 11 ft, starting to decay on Sun morning near the Revillagigedo Islands. A new set of NW swell will reach the offshore waters of Baja California Norte Sun night, with seas peaking near 12 ft by Mon night into early Tue. This reinforcing swell event will also help to maintain seas 8 ft or greater across the waters W of the Baja peninsula through late on Thu. Otherwise, a ridge will prevail W of the Baja California peninsula through the forecast period. A weak pressure pattern will support gentle to locally moderate winds off the coast of Baja California Norte and light to gentle winds across the remainder of the open waters off the coast of Mexico through the remainder weekend. Mainly light winds are expected across the Gulf of California during this time. High pressure will build by early next week, tightening the pressure gradient over the area, which will result in moderate to fresh NW winds off the coast of Baja California through Thu. This will also bring fresh to locally strong winds along the Gulf of California by Tue, continuing through late Thu. Otherwise, the next Tehuantepec gap wind event is forecast for Wed evening through Thu morning, followed by a stronger gap wind event during the weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... The pressure gradient between a ridge shifting eastward across the SE United States and the equatorial trough will support fresh to strong NE to E winds over the Papagayo region, and fresh to locally strong winds over the Gulf of Panama region through late Sun morning. Winds will diminish thereafter as the area of high pressure weakens and the pressure gradient loosens. REMAINDER OF THE AREA... The pressure gradient between high pressure of 1023 mb centered near 27N131W and lower pressure in the vicinity of the ITCZ is supporting fresh trade winds N of the ITCZ to near 16N and W of 120W. The ridge will strengthen on Sun and will support fresh to strong trades over the tradewind zone N of the ITCZ through Thu night. Long period NW swell is propagating across the forecast area, supporting seas of 8 ft or greater over much of the forecast waters N of the equator and W of 113W. The swell will continue to propagate SE, covering much of the forecast waters N of the Equator and W of 110W by Sun. A new set of long period NW swell is propagating into the NW waters with seas expected to peak near 13 ft Sun. $$ NR
