Full Alert Message

Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 0405 UTC Thu Jun 18 2026 Corrected Within 250 nm of Mexico section 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 0315 UTC. ...TROPICAL WAVES... The southern portion of the axis of a central Caribbean Sea tropical wave crosses the central part of Panama and into the far eastern part of the Pacific basin along 78W. It is moving westward around 20 kt. Scattered moderate convection is ahead of the axis from 03N to 07N between 82W and 89W. The axis of a tropical wave is near 93W north of 03N to inland southeastern Mexico. It is moving westward at 15 to 20 kt. Scattered moderate convection is within 120 nm east of the wave from 12N to 14N. The axis of a tropical wave is near 111.5W from 04N to 16N. It is moving westward at about 15 kt. Scattered moderate convection is within 60 nm east of the wave from 04N to 07N, and within 60 nm west of the wave from 06.5N to 09N. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from northern Colombia westward to northern Costa Rica to the coast at 10.5N86W, then to 13N103W and to 07N118W. The ITCZ extends from 07N118W to 07N130W to beyond 08N140W. Scattered moderate to isolated strong convection is within 180 nm south of the ITCZ between 136W-140W. Scattered moderate convection is within 120 nm north of the trough between 104W-106W, and within 60 nm south of the trough between 106W-109W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...Corrected A surface trough extends from California/Nevada border south- southeastward across the northern Gulf of California and across the length of the Baja California peninsula. The pressure gradient between the trough and surface ridging to the west is supporting mainly moderate NW-N winds offshore Baja California to the north of Cabo San Lazaro, and moderate to fresh southeast to south winds in the Gulf of California, locally strong N of 29N. A weak pressure gradient across the remainder discussion waters is supporting light to gentle winds. Moderate seas dominate the offshore waters with heights of 5 to 7 ft in south to southwest swell. Seas are 2 to 4 ft in the Gulf of California, except for higher seas of 3 to 5 ft in long-period south swell in the far southern portion of the Gulf and at the entrance. For the forecast, gentle to moderate winds will prevail across the waters of Baja California, pulsing to locally fresh speeds at night. Gentle to occasionally moderate winds are expected inside the Gulf of California and near the tip of Baja California Sur, reaching to locally fresh to strong speeds tonight into early Thu. Light to gentle winds will prevail over the waters between Cabo Corrientes and Tehunatepec during the forecast period. Moderate seas in mainly southerly swell will prevail through the next several days, slight in the Gulf of California. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Mainly light to gentle winds under a weak pressure gradient prevail across the offshore waters along with moderate seas due to long-period south to southwest swell. Satellite imagery shows numerous thunderstorms over the western sections of Nicaragua extending offshore for 60 nm. Scattered moderate to isolated strong convection extends from El Salvador and southeastern Honduras southeastward to offshore Nicaragua for 100 nm. This activity also reaches to just inland Nicaragua. Scattered showers and thunderstorms are over southeastern Mexico. Isolated showers and thunderstorms are over the offshore waters of Colombia. For the forecast, gentle to occasionally moderate S to SE winds and moderate seas will prevail across the offshore waters between Ecuador and the Galapagos Islands through at least Sun night. Moderate winds will pulse to fresh in diurnal offshore flow in the immediate Gulf of Papagayo. Light to gentle winds and slight to moderate seas in SW swell are forecast elsewhere through at least the next several days. ...REMAINDER OF THE AREA... The surface trough that was near 140W earlier has continued to pull farther away from the discussion area. In the wake of the trough, latest satellite scatterometer data passes generally show light to gentle east to southeast winds north of the ITCZ to near 12N west of 130W, mostly fresh east to southeast winds from 12N to 15N west of 137W, gentle to moderate trade winds from 15N to 21N west of 130W, and light to gentle anticyclonic winds north of 21N west of about as ridge axis is analyzed along 23N/24N west of about 120W. A weak trough is analyzed from near 30N132W to west of the area at 28N140W. The scatterometer satellite data indicates moderate to fresh northeast winds north of 30N west of the trough. Latest satellite altimeter data and Sofar Ocean Spotter buoys reveal seas of 5 to 7 ft over the waters waters W of 125W and 4 to 6 ft east of 125W. Satellite imagery shows scattered showers and isolated thunderstorms south of 16N west of 120W. For the forecast, seas will build to rough state south of and near the Equator and east of 120W beginning Sat as a new set of southerly swell begins to move through this part of the area. Winds may pulse to fresh in the west-central waters at times. Otherwise, little overall changes are expected in and winds and seas going into the weekend.
