000 AXPZ20 KNHC 131559 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Wed Mar 13 2024 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 1200 UTC surface analysis and satellite imagery through 1600 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 07N78W to 04N85W to 04N98W. The ITCZ continues from 04N98W to 04N117W to 03N140W. Isolated moderate convection is noted within 90 nm north of the trough between 82W and 98W and also within 60 nm of the ITCZ between 98W and 123W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds are funneling along the west coast of Baja California north of Cabo San Lazaro due to the pressure gradient between high pressure over the Pacific and lower pressures over western Mexico. Pulses of strong winds may be north of Punta Eugenia. Seas are 8 to 10 ft in the area of these winds. Elsewhere, gentle to moderate mostly variable winds and moderate seas in mixed long- period southerly and northwesterly swell are over the remainder of the area. For the forecast, fresh to locally strong winds will pulse offshore western Baja California through Thu morning due to the pressure gradient between high pressure over the Pacific and low pressure northwest of Baja California Norte. This pattern will also support a brief pulse of fresh to strong winds over the northern Gulf of California Thu. Long period northwest swell will continue SW to the Revillagigedo Islands, building seas 8 to 10 ft through the rest of the day. A second set of 12 to 14 ft long period NW swell will impact the offshore waters north of 27N this evening into Thu night before it begins to subside. For the remainder of the forecast period long period NW swell will continue at around 10 ft. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR Fresh to strong NE winds are present within the Gulf of Papagayo region, where seas are 5 to 8 ft. High pressure building north of the western Caribbean supports these winds along with pulsing fresh NE winds in the Gulf of Panama, where seas are 5 to 8 ft. Elsewhere, seas to 8 ft in S swell are building southwest of the Galapagos Islands. Light to gentle variable winds and moderate seas prevail across the remainder of the region. For the forecast, high pressure will continue to support fresh to strong northeast to east gap winds in the Papagayo region through Fri morning, while the winds in the Gulf of Panama will diminish to moderate winds this evening. The S swell south of the Galapagos Islands will subside to below 8 ft by this evening. Light to gentle winds and moderate seas will continue elsewhere through the forecast period. ...REMAINDER OF THE AREA... High pressure dominates these waters, and it is driving the weather pattern. Fresh to localized strong NE to E winds from 06N to 23N mainly west of 126W due to the pressure gradient between the 1030 mb high pressure near 37N136W and relatively lower pressures in the deep tropics. Combined seas are 8 to 11 ft. Gentle to moderate winds and moderate seas are elsewhere. Looking ahead, fresh to localized strong trade winds will continue through tonight. Seas will remain 8 to 11 ft with these winds before beginning to subside tonight through Fri. Another set of 12 to 14 ft long period northwest swell will impact the waters north of 28N and east of 125W tonight into Thu night before it begins to subside. Yet, another set of long- period northwest swell will enter the far northwest waters beginning Fri morning and propagate southeast through the weekend. $$ KRV
