000 AXPZ20 KNHC 050927 CCA TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Jun 5 2023 Corrected satellite imagery time Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 0400 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from northern Colombia near 10N74W to 11N86W to 11N100W to 09N112W to low pressure near 08N122W 1011 mb to 07N135W and to beyond 04N140W. Scattered moderate to strong convection is seen from 05N to 11N between 92W-98W. Scattered moderate to isolated strong convection is from 06N to 10N between 77W-87W, and within 60 nm N of the trough between 114W-120W. Scattered moderate convection is within 120 nm N of the trough between 124W-127W and within 60 nm S of the trough between 123W-128W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure is over the offshore forecast waters of Baja California producing gentle to moderate NW to N winds, with the exception of fresh NW winds near Cabo San Lucas based on recent scatterometer data. Seas are 5 to 7 ft in mixed NW and S swell across this area. In the Gulf of California, winds are light and variable with seas in the 1 to 2 ft range, expect 3 to 5 ft near the entrance to the Gulf. Gentle to locally moderate NW winds prevail across the remainder of Mexican offshore waters, with seas of 5-7 ft due to SW swell. For the forecast, the high pressure over the area will remain in control of the weather pattern through at least mid-week with little change in winds and seas. As a result, expect gentle to moderate NW to N winds, with the exception of moderate to fresh winds between Cabo San Lazaro and Punta Eugenia. In addition, fresh NW winds are expected near Cabo San Lucas at night through the forecast period. Developing ow pressure over the northern Gulf of California will support fresh to locally strong S to SW winds Mon night and Tue night along with seas building to 7 or 8 ft on Mon night. Gentle to moderate NW winds across the SW Mexican offshore waters will diminish to light to gentle speeds on Mon with building seas of 7 to 8 ft in SW swell late on Mon and Mon night. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle SW to W winds and seas of 4-6 ft in a S to SW swell are across the Central America offshore waters while gentle to moderate southerly winds and seas in the 7-9 ft range in SW swell are noted between Ecuador and the Galapagos Islands per latest altimeter data pass over that part of the area. Moderate to locally fresh S winds prevail across the offshore waters of Colombia with seas of 5-8 ft due to a S to SW swell. In the Gulf of Panama, light to gentle winds and 1-3 ft are present, with the exception of 4-6 ft at the entrance to the Gulf due to a SW swell. Scattered showers and thunderstorms are over the most of the offshore waters of Panama and Costa Rica. For the forecast, mainly gentle to moderate SW to W winds will prevail through mid-week. Long-period cross equatorial SW swell producing seas to 9 ft will continue to propagate across the waters between Ecuador and the Galapagos Islands, reaching the offshore waters of West Panama by early Mon, with seas to 8 ft. This swell event will gradually subside Mon night into Tue. ...REMAINDER OF THE AREA... A ridge, anchored by a 1034 mb high pressure center well N of the area near 46N136W, dominates mainly the forecast waters N of 15N W of 110W generating a gentle to moderate anticyclonic flow. Winds increase some to moderate to fresh speeds on the northern semicircle of the aforementioned low pressure centers located along the monsoon. Seas are generally 5-7 ft across the open waters in mixed swell, with the exception of 7-9 ft seas S of 07N between 94W-117W due to a southerly swell event. Seas of 8-9 ft are likely in the vicinity of the low near 08N121W. For the forecast, the ridge will remain in place through at least mid-week. The westernmost low pressure along the monsoon trough will open-up into a trough while approaching 140W in about 42 hours. The low located near 08N121W will drift northward over the next couple of days. Long-period cross equatorial S to SW swell from the Southern Hemisphere will continue to propagate across most of the waters S of 10N between 92W-110W tonight into Mon. Seas generated by strong northerly winds just W of California will push S of 30N Mon through Tue, with seas 8-10 ft over the waters N of 25N between 120W-135W. $$ Aguirre
