Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sat Jun 13 2026 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 2000 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 81W extending from the Caribbean southward, moving westward at around 10 kt. Scattered moderate to strong convection is noted E of 83W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N86W to 12N103W to 07N140W. Two areas of low pressure are embedded within the monsoon trough, one is a 1008 mb low near 08N127W, and the other a 1007 mb low near 09N135W. Scattered moderate convection is noted from 05N to 14N between 96W and 109W. Scattered moderate to strong convection is noted along the monsoon trough in the vicinity of the lows from 03N to 10N between 125W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Weak 1014 mb high pressure is centered west of the area near 27N122W. A surface trough extends across the Gulf of California. The pressure gradient between these features is supporting gentle to locally moderate winds west of Baja California, extending southward to near the Revillagigedo Islands, and over the Gulf of California. A weak pressure gradient across the remainder of the discussion waters is supporting light to gentle winds over the waters south of southern and southwestern Mexico. Seas are in the 5-6 ft range over the open waters off Mexico, and 3 ft or less in the Gulf of California. For the forecast, light to gentle winds will prevail across the waters of Baja California through tonight, increasing slightly thereafter. Gentle to occasionally moderate S to SW winds are expected inside the Gulf of California and near the tip of Baja California Sur. Light to gentle winds will dominate the waters between Cabo Corrientes and Tehunatepec. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh winds prevail in the Gulf of Papagayo. Gentle to moderate winds are found between the Galapagos Islands and Colombia. Gentle winds are found elsewhere. Seas are in the 5-7 ft range between the Galapagos Islands and Colombia, and 4-6 ft elsewhere. For the forecast, gentle to moderate winds and moderate seas will prevail across the offshore waters through the weekend. Moderate winds will pulse to fresh in diurnal offshore flow in the immediate Gulf of Papagayo into early next week, possibly reaching strong speeds late tonight and early Sun as a tropical wave approaching the area enhances gap flow. ...REMAINDER OF THE AREA... A weak pressure gradient is supporting light to gentle winds, locally moderate, N of the monsoon trough. Two areas of low pressure are embedded within the monsoon trough, one is a 1008 mb low near 08N127W, and the other a 1007 mb low near 09N135W. Moderate to fresh winds are S of the monsoon trough and W of 124W, reaching strong speeds S of two areas of low pressure. Gentle to moderate winds are elsewhere S of the monsoon trough. Rough seas to 9 ft are over the waters S of the two lows, with mainly moderate seas found elsewhere. For the forecast, fresh to occasionally strong winds, and rough seas, are expected near the low pressure areas along western portion of the monsoon trough into early next week. Elsewhere, moderate or weaker winds, and moderate seas, will prevail across the open waters.
