290 AXPZ20 KNHC 111436 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Thu Jul 11 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 1430 UTC. ...TROPICAL WAVES... The axis of a tropical wave is north of 07N to southwestern Mexico near 106W, moving west at 10-15 kt. Any nearby convection is discussed in the ITCZ/monsoon trough section below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 15N102W to 10N121W. The ITCZ extends from 10N121W to 08N140W. Scattered moderate isolated strong convection is noted from 03N to 09N and E of 89W, and from 05N to 09N between 125W and 132W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to strong winds are over the Gulf of Tehuantepec with seas in the 5-6 ft range. Elsewhere, a weak pressure gradient across the discussion waters is resulting in light to gentle breezes across most the Mexican offshore waters, with moderate winds over the Gulf of California. Seas are 4-5 ft in S swell over the open Pacific waters and 2-4 ft over the Gulf of California. For the forecast, fresh to strong northerly winds will pulse in the Gulf of Tehuantepec through the end of the week, increasing slightly this weekend. These winds will build rough seas by the weekend. A surge of southerly fresh to strong winds may develop in the northern Gulf of California tonight. Fresh to strong southerly flow will prevail across the Gulf of California Fri night through Sat night. Winds will be moderate or weaker elsewhere, with mainly moderate seas. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh NE winds are downwind of the Gulf of Papagayo. Light to gentle winds are elsewhere N of the monsoon trough. Gentle to moderate winds are noted S of the monsoon trough. Seas across the waters are in the 4-6 ft range in S swell. For the forecast, fresh to strong winds will develop in the Papagayo region tonight through the upcoming weekend, possibly near gale at times with building seas. These winds and seas may spread westward to the waters well offshore Guatemala and El Salvador by early Fri. Southerly swell may build seas slightly offshore Ecuador this weekend. Fairly tranquil conditions are forecast elsewhere. ...REMAINDER OF THE AREA... Moderate to fresh winds and seas of 5-7 ft are noted over the NW waters, mainly north of 20N and west of 130W. Moderate or weaker winds and seas in the 4-6 ft range prevail elsewhere. For the forecast, expect moderate to fresh N to NE winds and 5-7 ft seas north of the 20N and west of 125W through the end of the week. Tradewinds will be gentle to moderate NE winds between 10N-22N through the end of the week. Looking ahead, large N to NE swell should move south of 30N and west of 120W beginning on Fri. Southerly swell to 8 ft may reach north of equator to 10N and between 110W and 125W this weekend into early next week. Winds may freshen south of the ITCZ and west of 110W early next week. $$ AL
