000 AXPZ20 KNHC 022106 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Thu May 2 2019 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 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from western Panama near 08N82W to 09N90W to 07N107W. The ITCZ continues from 07N107W to 04N120W to 05N130W to 03N140W. Scattered moderate and isolated strong convection is noted from 04N to 10N between 83W and 92W, from 05N to 08N between 104W and 107W, and from 05N to 07N between 109W and 115W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pressure ridge enters the forecast waters near 32N128W, and extends south-southeastward to near the Revillagigedo Islands. Gentle to moderate winds prevail off the west coast of the Baja California peninsula, with seas in the 4-6 ft range. The ridge will weaken and shift southeast by the end of the weekend as a front or trough move into the area. Gulf of California: Light to gentle winds will dominate the gulf waters through Sat evening. On Sun, a front or trough will approach Baja California Norte by the end of the weekend into early next week, increasing gap winds in the northern Gulf of California to near gale Sun night into Mon, gradually diminishing thereafter. Otherwise, the remainder offshore waters of Mexico will be dominated by light to gentle winds and seas of 3-5 ft. Ongoing agricultural burning, which are normally carried on during this time of year in southeast Mexico and Central America, is generating smoke leading to hazy conditions along and adjacent to the coast of Mexico from Guerrero to the Gulf of Tehuantepec. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gulf of Papagayo: Moderate daytime winds will pulse to fresh during the overnight hours. Winds will diminish across the gulf of Papagayo through early Sat, and then again early Tue. Otherwise and elsewhere, light to gentle winds prevailing through the weekend, and seas in the 4-6 ft range will prevail. REMAINDER OF THE AREA... A high pressure ridge enters the forecast waters near 32N128W, and extends south-southeastward toward the offshore waters. This ridge is weakening due to a cold front that has entered and extends from 32N135W to 26N140W with scattered showers within 60 nm on either side of the boundary. Winds will briefly strengthen ahead of the cold front over the NW waters today through Fri morning. The front will continue to move eastward and dissipate W of the Baja California Peninsula offshore waters by Sun. Elsewhere, the pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh trade winds across the west central waters, along with seas in the range of 5-8 ft. These trades and seas will diminish and subside during the weekend as the pressure gradient weakens. Also, cross-equatorial southwest swell reaching the equator will build seas greater than 8 ft across the equator tonight. The swell will gradually decay and subside Sun through early next week. $$ Lewitsky
