000 AXPZ20 KNHC 010156 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0200 UTC Wed May 1 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 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 08N78W to 06N96W. The ITCZ continues from 06N96W to beyond 05N140W. Scattered moderate convection is occurring within 120 nm of the trough between 83W and 93W. Scattered moderate and isolated strong convection is observed within 180 nm of the ITCZ axis between 110W and 127W. ...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. 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 only fresh or weaker. Ship LAQM7 and an earlier altimeter pass indicated 8-9 ft seas in the vicinity of 30N125W, larger than suggested by wave model guidance. These seas, associated with primarily northerly swell, should diminish on Wed. A weak cold front will reach our NW corner at 30N140W late Wed, but no significant winds or seas will likely be 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 of 8 to 9 ft should reach the southern border near the equator and 120W late Thu. This 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 02N and west of 100W. $$ Landsea
