Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1005 UTC Thu Nov 20 2025 Corrected Remainder of the Area 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 0600 UTC surface analysis and satellite imagery through 0945 UTC. ...SPECIAL FEATURES... Large NW swell to arrive over the northern and central waters: A cold front that has just started to move into the far NW corner of the area will sweep across the northern and central waters through Fri night while weakening. A set of large NW swell behind the front will support a wide expanse of rough seas beginning late tonight over the northern and central waters. Seas exceeding 8 ft will occur north of 24N west of 117W by late on Fri. Very rough seas of 12 to 14 ft containing wave periods of 12-14 seconds are expected north of 27N between 121W and 131W also by late on Fri. Seas across this area are forecast to subside to below 12 ft on Sat, and to below 8 ft early next week. Please read the latest HIGH SEAS FORECAST issued by the National Hurricane Center at website- https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from northern Colombia southwestward to 08N80W, and continues west-northwest to 9.5N90W to 08N103W to 07N110W and to 08N117W, where it transitions to the ITCZ to 09N124W to 08N130W and to west of the area at 08N140W. Scattered moderate to strong convection is seen from 03N to 07N between 78W-81W. Scattered moderate convection is within 30 nm of the ITCZ west of 134W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section for details on an upcoming large swell event. Gentle to moderate NW to N winds are over the offshore waters of Baja California, with the moderate speeds confined to south of Cabo San Lazaro. Seas are 6 to 8 ft in NW swell north of Cabo San Lazaro and 5 to 7 ft south of Cabo San Lazaro. In the Gulf of California, moderate W to NW winds are over the central portion along with seas of 3 to 4 ft, and light to gentle NW to N winds are over the remainder of the Gulf along with seas of 3 to 4 ft, except in the far northern portion, where seas are 3 ft or less. Elsewhere, a weak pressure gradient allows for light to gentle winds, with slight to moderate seas in NW swell, For the forecast, the 6 to 8 ft seas north of Cabo San Lazaro will subside below 8 ft this afternoon. A cold front is forecast to enter the Baja California Norte offshore waters tonight, followed by large swell bringing rough seas to the waters N of Cabo San by Sun. These seas will slowly subside through Tue. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh NE winds are ongoing in the Gulf of Papagayo and downwind to near 89W along with moderate seas. Elsewhere across the Central America offshore waters, light to gentle winds and slight seas prevail, except for moderate N winds in the Gulf of Panama. Moderate S to SW winds are over the waters between Ecuador and the Galapagos Islands along with moderate seas. Satellite imagery shows scattered moderate to isolated strong convection over and near northern and central Panama as the monsoon trough passes just south of these locations. Similar activity is noted west of Colombia to near 81W and south of the Gulf of Panama to near 04N. For the forecast, moderate to fresh NE to E winds and moderate seas are expected in the Gulf of Papagayo into early next week. Moderate or lighter winds and slight to moderate seas are forecast elsewhere into early next week. ...REMAINDER OF THE AREA...Corrected Please see the Special Features section for details on an upcoming large swell event. Moderate to fresh N to NE winds are present north of 20N between 115W and 125W, and also from 20N to 28N between 125W and 131W. Seas are 6 to 9 ft in long-period NW swell with these winds. A cold front has recently entered to the far NW part of the area, followed by fresh N winds. Elsewhere, high pressure is over the remainder of the area N of about 20N and west of 110W. The gradient between the high pressure and relatively lower pressure in the tropics is generally allowing for fresh to strong trade winds from 12N to 22N between 130W and 140W along with seas of 8 to 10 ft as were highlighted in overnight altimeter satellite data passes, and mostly fresh trade winds elsewhere from 09N to 23N W of 124W along with seas of 7 to 9 ft in long-period N swell. Moderate to fresh trade winds are present elsewhere between the ITCZ and 25N and W of 120W. For the forecast, the gradient between the aforementioned high pressure and relatively lower pressure in the tropics continue to support the previously mentioned fresh to strong trade winds through early Fri as the next cold front pushes southward toward 20N. This cold front has recently entered the far NW waters tonight, followed by fresh NW to N winds and rough seas. Model guidance suggests that low pressure is expected to from offshore the southern California/Baja California Norte border on Fri, and move over the waters west of Baja California early on Sat before shifting eastward across northern Baja California and across the northern Gulf of California later on Sat. The low may possibly be accompanied by fresh to strong winds. Seas in excess of 8 ft are expected west of Baja California at that time as peak seas subside to just below 12 ft. Seas over these waters will subside further, to below 8 ft, early next week.
