000 AXPZ20 KNHC 272135 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1605 UTC Tue Apr 27 2021 Corrected Remainder of the Area section 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 1200 UTC surface analysis and satellite imagery through 1545 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 09N84W to 08N95W to 12N107W and to 09N120W, where overnight scatterometer indicates that it transitions to the ITCZ to 07N130W to beyond the area at 05N140W. Scattered moderate to isolated strong convection from 03N to 07N between 83W-88W, within 180 nm south of trough between 93W-101W, from 04N to 06N between 101W-106W, within 120 nm north of ITCZ between 135W-140W and within 60 nm north of ITCZ between 127W- 135W. Scattered moderate convection is within 60 nm north of trough between 109W-112W. within 60 nm south of trough between 114W-115W and within 60 nm north of ITCZ between 122W-124W. 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 by early this afternoon. A small area of strong northwest winds will develop over the central Gulf of California late tonight and diminish to mainly fresh winds Wed morning. 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 begin to move propagate into the region tonight and through early Thu at which time it will begin to decay. Prior to doing so, the swell will induce maximum seas of 8 ft. REMAINDER OF THE AREA...Corrected A dissipating cold front extends from far northwestern Mexico southwestward to across central Baja California and to 26N120W and to near 23N126W. Behind it, a trough is analyzed from near 30N118W to 26N124W. High pressure is present elsewhere over the area, with a 1021 mb high center analyzed at 31N135W. A weak pressure gradient remains between the high pressure and lower pressure in the vicinity of the ITCZ. This gradient is supporting moderate to fresh northeast winds north of the ITCZ to near 15N and west of about 124W. 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. Slightly stronger high pressure will build southward into the area through the end of the week, while at the same time a cold front approaches the northwest corner of the area. Expect for the areal extent of the aforementioned winds to increase through the week as a surface trough possibly develops in the central tropical region and tracks westward. If this trough materializes, scattered showers and thunderstorms will most likely increase over the central part of the area. $$ Aguirre
