000 AXPZ20 KNHC 292214 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2047 UTC Mon Apr 29 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 10N75W to 10N85W to 06.5n92w, where it transitions to ITCZ, and continues on to 06N110W to to 06N122W, then resumes near 04.5N130w to beyond 03.5N140W. Scattered to locally numerous moderate to strong convection is noted from 02.5N to 09N east of 88W. Scattered moderate to strong convection is noted within 180 nm N of ITCZ between 96W and 107W, from 03.5N to 09.5N between 122W and 131W, and within 120 nm N of ITCZ between 133W and 144W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure extends from the far NE Pacific SE to near 26N130W to just southeast of the Revillagigedo Islands. A weak surface through across the waters of Baja California Norte to near 16N122W interrupts the ridge N of 25N. The resultant pressure gradient between the area of high pressure and a surface trough across Baja California is supporting gentle to moderate NW to N winds over the offshore waters of Baja California with seas in the 4-5 ft range. These conditions will prevail throughout the week. Gulf of California: Strong S to SW winds across far north portions of the Gulf will continue through early Tue before diminishing. Seas across that area will build to 5-7 ft this afternoon through tonight. Light to gentle winds will then prevail across most of the Gulf of California through the week. Gulf of Tehuantepec: Light to moderate winds and seas of 4 to 6 ft will prevail through Fri night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gulf of Papagayo: Fresh to strong NE to E winds over the Gulf of Papagayo region will diminish Wed night. Gulf of Panama: Fresh N winds over the Gulf of Panama will become light to moderate Tue afternoon. 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 Central America and the coast of SE Mexico, including the Gulf of Tehuantepec region. REMAINDER OF THE AREA... High pressure prevails over the northern waters, extending from a narrow ridge centered across the far NE Pacific through 30N136W to 20N140W. The pressure gradient between the high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh tradewinds N of the ITCZ to near 20N and west of 120W. Combined seas of 6-8 ft prevail over these waters in a mix of NW and SW swell and tradewind waves. These conditions will prevail through the remainder of the week. N swell is producing seas of 8 ft N of 29N between 123W and 132W. Seas will subside below 8 ft by midweek. Cross- equatorial SW swell will propagate through much of the forecast area east of 120W Thu afternoon through Sat. Combined seas of 8 ft or higher will generally be confined to the waters south of the 02S and west of 95W. $$ Stripling
