000 AXPZ20 KNHC 072135 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Mon Mar 7 2022 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 1800 UTC surface analysis and satellite imagery through 2010 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from Colombia near 10N75W to 05.5N81W to 07N88W to 04N106W. The ITCZ stretches from 04N106W to 08.5N130W to beyond 07.5N140W. Scattered moderate isolated strong convection is noted within 30 nm of line from 06.5N82W to 05.5N87W, and from 06.5N to 10.5N W of 122W. Scattered moderate convection is noted S of 02N between 88W and 92W and from 04N to 06N between 106W and 117W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO A relatively narrow surface ridge extends from strong high pressure across the NE Pacific through 30N131W to near 18N107W. The pressure gradient between this ridge and lower pressure across the Sierra Madre Occidentales of Mexico is producing mainly fresh NW to N winds within 150 nm offshore of Baja California N of Cabo San Lazaro, and moderate N winds elsewhere southward to 18N. Seas are 6 to 9 ft in NW swell across the offshore waters N of Cabo San Lazaro, and 6 to 8 ft elsewhere. Moderate side shore winds are occurring near the coast along Cabo Corrientes and Puerto Angel. Otherwise to the S of 18N, winds are light and seas are 4 to 6 ft. Inside the Gulf of California, fresh northerly winds prevail south of the Tiburon Basin, where seas are 3-5 ft, except to 6 ft at the mouth of the Gulf. Fresh northerly winds offshore Baja California Norte today will diminish slightly tonight. NW swell and current seas of 7 to 9 ft will also decay to 6-8 ft in this area. High pressure will build southward between 125W and 140W through midweek, and maintain moderate winds offshore of Baja and fresh to locally strong winds inside the Gulf of California through Tue. Elsewhere, gentle to moderate winds and 4 to 7 ft seas will prevail into mid-week. Looking ahead, strong winds are expected to spread from north portions of the Gulf of California through the full length of the basin Thu night through Sat morning. A strong gale event is expected to develop across the Gulf of Tehuantepec during the weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Moderate NE winds are noted across the Papagayo region, with gentle to moderate N winds in the Gulf of Panama. Elsewhere, winds are light to gentle with seas of 3 to 5 ft. Winds across the Papagayo region will pulse to fresh tonight and Tue night before gradually diminishing through the end of the week. Moderate north winds in the Gulf of Panama will pulse nightly through mid week becoming light to gentle the remainder of the week. Gentle to moderate winds will prevail elsewhere. New SW swell will mix with WNW swell across the regional waters on Thu to raise seas slightly. REMAINDER OF THE AREA N of the ITCZ to 21N, widespread moderate to fresh NE to E winds prevail due to the pressure gradient between the ITCZ and the high pressure to the north. Seas are 8 to 11 ft in mixed swell. Across NW portions, fresh to strong SE winds N of 24N and W of 138W are associated with the pressure gradient between a trough west of the area and high pressure. Scattered moderate convection is seen on satellite imagery there from 24.5N to 27N W of 139W. To the S of the ITCZ, gentle to moderate E to SE winds prevail with seas of 5 to 7 ft. Winds will subside across waters N of 25N as the ridge remains in place. However, the pressure gradient S of 25N and W of 122W will support fresh trades and seas of 8 to 10 ft most of the week. The trough W of the area will weaken, allowing winds to relax to fresh and seas to fall under 8 ft by midweek. $$ Stripling
