The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0307 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 13N94W to 09N120W to a 1007 mb low pressure near 09N128W to another 1007 mb low pressure near 09N139W to 09N140W. Scattered to numerous moderate and isolated strong convection is noted from 03N to 12N between 110W and 140W. Scattered moderate convection is depicted from 06N to 14N between 92W and 100W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weak pressure gradient prevails across the area. With the weak pressure gradient, light to gentle winds prevail over the discussion waters, except gentle to locally moderate winds off Cabo San Lucas. 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 Sat night, increasing slightly thereafter. Gentle to occasionally moderate SW to S 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... Gentle to moderate winds prevail in the Gulf of Papagayo as well as between the Galapagos Islands and Colombia. Light to 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 into the weekend. Winds may pulse to moderate to locally fresh in diurnal offshore flow in the immediate Gulf of Papagayo and near the Gulf of Guayaquil during the upcoming weekend into early next week. ...REMAINDER OF THE AREA... Broad troughing prevails across the waters N of 20N. The pressure gradient between this trough, and high pressure NW of the area is supporting moderate to locally fresh winds over the NW waters. Gentle to moderate winds are elsewhere N of the monsoon trough and west of 130W. Light to gentle winds prevail elsewhere N of the monsoon trough. Moderate to fresh winds are S of the monsoon trough and W of 125W, with gentle to moderate winds elsewhere. Northerly swell is bringing rough seas over the waters N of 27.5N between 129W and 138W. Mainly moderate seas are found elsewhere, except locally rough south of the equator. For the forecast, moderate or weaker winds are expected across the much of the open waters, except at least moderate to fresh winds near transient embedded low pressure areas along western portion of the monsoon trough through early next week. Northerly swells mixed with the longer period southerly swells with seas of 7-9 ft will linger across the N-central waters through tonight before decaying. Otherwise, moderate seas will dominate the open waters, locally rough in the S-central waters through Sat, as well as near any of the embedded lows within the monsoon trough. $$ KRV ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC130848_C_KWBC_20260613084912_32440682-2708-TWDEP.txt ****0000003926**** AXPZ20 KNHC 130848 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 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.
