000 AXPZ20 KNHC 270749 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Tue Apr 27 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 08.5N84W to 08N94W to 11N113W to 08N121W. The ITCZ extends from 08N121W to 05N140W. Scattered moderate isolated strong convection was noted from 03N to 07N between 82W and 90W, from 03N to 08N between 93W and 98W, and from 03N to 11N between 101W and 112W. Scattered moderate convection was noted from 04N to 08N between 120W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Strong to near gale force winds are noted over the northern Gulf of California, with seas in the 5-6 ft range. Gentle to moderate winds prevail elsewhere over the open waters off Mexico. Seas are in the 3-5 ft range in a mix of northwest and south swell over the open waters off Mexico. For the forecast, strong to near gale SW to W gap winds over the northern Gulf of California will diminish early today. High pressure will build west of the region 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 north winds across the Gulf of Panama. Light to gentle winds persist elsewhere. Seas are in the 4-6 ft range in 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. Additional southerly swell will move into the region by mid-week. REMAINDER OF THE AREA... A cold front extends across northern Baja California to near 25N122W, then a dissipating frontal trough extends from 25N122W to 22N134W. This front will weaken today as it moves across the rest of waters north of 25N. High pressure is building in the wake of the front. A weak pressure gradient remains between this building high pressure and lower pressure in the vicinity of the ITCZ. This gradient is supporting moderate winds north of the ITCZ to near 15N and west of 125W. Seas over this area are in the 5-7 ft range. Gentle to moderate winds and seas in the 4-6 ft range prevail elsewhere. The ridge will gradually build through the week, with areal extent of moderate trade winds increasing through the week. $$ AL
