000 AXPZ20 KNHC 260719 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon Apr 26 2021 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 0600 UTC surface analysis and satellite imagery through 0840 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N84W to 08N94W to 10N113W to 09N120W. The ITCZ continues from 09N120W to 05N140W. Scattered moderate convection is noted from 03N to 08N between 80W and 90W. Scattered moderate to isolated strong convection is observed from 04N to 14N between 102W and 111W, from 06N to 13N between 111W and 125W, and from 02N to 07N between 125W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gentle to moderate winds prevail west of the Baja California peninsula. Light to gentle winds prevail elsewhere. Seas are in the 3-5 ft range over the open waters off Mexico, and 1-3 ft over the Gulf of California. For the forecast, fresh to strong SW to W gap winds will pulse into the northern Gulf of California today, ahead of a trough moving through the region. High pressure will build west of the region in the wake of the trough, supporting fresh winds off Baja California by mid week. Farther south, slight to moderate seas will build by mid week as a new set of southerly swell arrives. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate to fresh gap winds prevail over the Gulf of Papagayo and moderate N winds across the Gulf of Panama. Light to gentle winds persist elsewhere. Seas are in the 4-6 ft range with lingering southerly swell. For the forecast, gentle to moderate winds will persist across the region, with subsiding southerly swell. Fresh to strong gap winds will pulse mainly overnight across the Gulf of Papagayo tonight and again Mon night into Tue. Additional southerly swell will move into the region by mid week. REMAINDER OF THE AREA... A cold front from 30N118W to 25N135W will weaken today as it moves eastward across the waters north of 25N. The subtropical ridge over the northern waters has weakened and loosened the pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ. The pressure gradient will support mostly moderate trades through mid week. Seas near 8 ft in mixed swell will prevail mainly from 06N to 12N west of 135W this morning. Elsewhere modest winds and seas will prevail. Looking ahead, trade winds may increase later in the week over tropical waters west of 125W as the subtropical ridge builds to the north. $$ AL
