000 AXPZ20 KNHC 021517 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1314 UTC Sun Apr 2 2017 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The ITCZ is located south of the discussion waters. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure of 1033 mb centered north of the area near 35N139W extends a ridge southeastward to near the Revillagigedo Islands. Gentle to moderate winds prevail off the west coast of the Baja California peninsula, while light to gentle winds are seen elsewhere over the forecast waters. Seas in the 6 to 8 ft range are present off the west coast of the Baja California peninsula, 3 ft or less over the Gulf of California, and 4 to 6 ft over the remainder of the forecast waters. Seas will subside this afternoon as the northwesterly swell continues to decay. Another set of northwest swell will build seas to between 8 and 12 ft offshore of Baja California Norte and to between 6 and 9 ft offshore of Baja California Sur by Monday evening, then seas will subside to below 8 ft by Wednesday morning. Another round of NW swell will arrive on Friday, but seas of 8 ft or greater are only expected N of 27N. Looking ahead, a cold front will cross the Gulf of Mexico late next week. High pressure building southward behind the cold front could produce near gale to gale force winds in the Gulf of Tehuantepec Thursday night and Friday. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate NE to E winds will pulse over the Gulf of Papagayo during the late night and early morning hours through Thursday. Otherwise...light to gentle winds and seas in the 3-6 ft range will prevail over the forecast waters through the week. REMAINDER OF THE AREA... High pressure resides over the northern waters. The pressure gradient between this area of high pressure and the equatorial trough is resulting in moderate to fresh winds over the trade wind belt. Seas within this area range between 7 and 10 ft as long period northwest swell mixes with shorter period northeasterly wind waves. Seas over the northern waters are in the 10-14 ft range primarily in northwesterly swell. These seas will gradually subside through Wednesday. The next round of NW swell will cause seas N of 20N to build to between 8 and 11 ft Wednesday afternoon through Thursday night. A cold front will usher in a more significant swell event on Friday night. Seas could peak around 13 ft near 30N on Friday night and Saturday. $$ cam
