000 AXPZ20 KNHC 302205 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2117 UTC Tue Apr 30 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 extends from 09N83W to 06N93W. The ITCZ continues from 06N93W to beyond 05N140W. Scattered moderate and isolated strong convection is occurring from 04N-08N east of 92W. Scattered moderate and isolated strong convection is also observed within 120 nm of the ITCZ axis between 108W and 125W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pressure ridge extends south-southeastward over the NE Pacific waters from 30N135W to near the Revillagigedo Islands. There should be little change during the next several days. This will support quiescent winds in the zones through at least Sun over the offshore waters and the Gulf of California. No significant long-period swell will be impacting the area through at least Sun. Ongoing agricultural burning, which are normally carried on during this time of year in SE 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... A moderate N to S pressure gradient across Central America will be enhancing NE winds over the Gulf of Papagayo during late night and morning hours through Thu morning. Elsewhere winds and seas will remain quiescent through the next several days. No significant long-period swell will be impacting the area through at least Sun. Ongoing agricultural burning, which are normally carried on during this time of year in SE Mexico and Central America, is generating smoke leading to hazy conditions from the Gulf of Tehuantepec to Nicaragua. REMAINDER OF THE AREA... A weak ridge prevails near 30N with a relatively modest pressure gradient south of the ridge, causing NE tradewinds to be fresh or weaker. A weak cold front will reach our NW corner at 30N140W late Wed, but no significant winds or seas are associated with it. The front should dissipate by Sat before reaching the Mexican offshore waters. Little change therefore is expected of the tradewinds during the next several days. Cross-equatorial SW swell will propagate through much of the forecast area east of 120W Fri through early Sun. Combined seas of 8 ft or higher will generally be confined to the waters south of the 05N and west of 113W. $$ Landsea
