####018003790#### AXPZ20 KNHC 131433 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Tue May 13 2025 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. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N85W to 08N94W to 10N120W. The ITCZ continues from 10N110W to beyond 06N140W. Numerous moderate to isolated strong convection is active from 04N to 08N east of 87W. Scattered moderate and isolated strong convection is noted from 03N to 10N between 93W and 105W, and from 04N to 10N between 120W and 135W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak cold front extends across Baja California Norte to Guadalupe Island. Moderate to fresh winds, and seas of 6-7 ft, are found off Baja California Norte. Gentle to moderate winds are south of Cabo San Lucas as well as south of Southern Mexico. Light to gentle winds are elsewhere over the open waters off Mexico. Elsewhere over the open waters, seas are in the 4-6 ft range. Fresh to locally strong winds are in the northern Gulf of California, with gentle to moderate winds elsewhere in the Gulf. Seas are in the 3-4 ft range in the northern Gulf of California, and 2-3 ft in the remainder of the Gulf. For the forecast, the front will slow down and weaken as it moves into the northern Gulf of California later today, before dissipating tonight into Wed. Strong winds may briefly pulse across the northern Gulf of California today ahead of and following the front. High pressure building in the wake of the front will freshen winds west of the Baja California peninsula through mid week, with large NW swell into Fri. Moderate or weaker winds and moderate seas, primarily in SW swell, will prevail elsewhere. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong winds, and seas of 6-8 ft are over and downstream the Gulf of Papagayo. Gentle to moderate winds, and seas of 5-6 ft are between Ecuador and the Galapagos Islands. Gentle winds, and seas of 4-5 ft, prevail elsewhere. For the forecast, moderate to fresh NE to E winds are expected in the Papagayo region through Fri, pulsing to fresh to strong at night into mid week. Gentle to moderate winds will persist elsewhere. Expect moderate to rough seas in long period SW swell between Ecuador and the Galapagos Islands Wed and Thu. Slight to moderate seas, primarily in SW swell, will prevail elsewhere. ...REMAINDER OF THE AREA.... A ridge prevails the waters north of 20N and west of 110W. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ is supporting moderate trade winds N of the ITCZ and west of 120W. Seas over these waters are in the 6 to 7 ft range. Gentle to locally moderate winds and seas of 5 to 7 ft are noted elsewhere in a mix of swell. For the forecast, the pressure gradient between high pressure over the waters N of 20N, and low pressure in the vicinity of the ITCZ will support moderate to fresh NE winds north of the ITCZ and west of 120W through mid week. Seas in the 8 to 9 ft range in NW swell will move into the waters north of 25N and west of 120W through mid week, and combine with seas from trade winds from 10N to 20N west of 130W through the latter part of the week. $$ AL
