The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0300 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 09.5N85W to 05N96.5W. The ITCZ continues from 05N96.5W to 04N120W to 04N140W. A second ITCZ is south of the Equator and runs from 02S105.5W to 03S140W. Scattered moderate convection is noted from 04N to 10N between 86W and 115W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to strong N to NE winds prevail across the Gulf of Tehuantepec along with seas 6 to 8 ft. Otherwise, a weak ridge dominates the offshore waters of Baja California. This pattern supports moderate to fresh NW to N winds with moderate seas. Gentle to locally moderate NW winds and slight seas are noted in the Gulf of California. Elsewhere across the Mexican offshore waters, light to gentle winds and moderate seas, primarily in southerly swell, prevail. For the forecast, pulsing fresh to strong northerly winds are expected in the Tehuantepec region the remainder of the week with seas building up to 7 or 8 ft. Moderate to locally fresh NW winds and moderate seas are forecast off Baja California through Fri night under the influence of a ridge. Fresh to strong SW winds may briefly develop in the northern Gulf of California Fri night ahead of a cold front approaching Baja California Norte, then moderate to fresh SW winds are expected through the upcoming weekend. Elsewhere, winds will be moderate or weaker with moderate seas through the next several days. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh gap winds are blowing across the Gulf of Papagayo and downwind to 88W. Seas are around 4 ft with these winds. Farther east, moderate N winds and 3 to 4 ft seas are present in the Gulf of Panama and just south of the Azuero Peninsula. Light to gentle winds and moderate seas dominate the remainder of the offshore forecast waters. For the forecast, fresh to locally strong gap winds are expected during the nighttime and early morning hours in the Papagayo region and downwind to about 89W through Fri. Toward the upcoming weekend, winds may increase to 30 kt with seas building to 8 or 9 ft in the Papagayo area as a stronger high pressure settles N of the area. Moderate northerly winds are forecast in the Gulf of Panama through the forecast period. Light to gentle winds and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... A decaying stationary front is over the NW corner of the forecast region and extends from 30N134W to 25.5N140W. Seas are around 7 ft in the wake of the front. E of front, a 1020 mb high pressure located near 33N125.5W extends a ridge across the remainder of the N waters, particularly N of 17N and W of 112W. The pressure gradient between the ridge and lower pressures in the vicinity of the ITCZ supports moderate to locally fresh winds in the trade wind zone, W of 113W. Seas of 6 to 7 ft are within these winds. Elsewhere, moderate or weaker winds and moderate seas are prevalent. For the forecast, a reinforcing front will move into our waters and merge with the stationary decaying front by Wed night. Then the front will continue to move eastward across the waters N of 20N while dissipating by Fri. Gentle to locally moderate winds will follow the front along with seas 6 to 7 ft. A high pressure center located ahead of the front will move SE between 120W and 130W and weaken some over the next 48-72 hours. Moderate to locally fresh trades are expected along the southern periphery of the ridge through at least Thu. $$ KRV ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC080919_C_KWBC_20260408091930_38666572-755-TWDEP.txt ****0000004259**** AXPZ20 KNHC 080919 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed Apr 8 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 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 09N84W to 06N97W. The ITCZ continues from 06N97W to 06N120W to 02N140W. A second ITCZ is south of the Equator and runs from 02S106W to beyond 05S140W. Scattered moderate to isolated strong convection can be found from 01N to 08N E of 84W to the coast of Colombia. A cluster of similar convective activity is seen from 02N to 05N between 125W and 130W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh N winds are noted across the Gulf of Tehuantepec along with seas of 5 to 7 ft. Otherwise, a weak ridge continues to dominate the offshore waters of Baja California supporting gentle to moderate NW to N winds with moderate seas. However, mainly moderate NW winds are observed in the vicinity of Cabo San Lucas and downstream to near 22N. Light and variable winds are observed across most of the Gulf of California, with the exception of light to gentle SE to S winds near the entrance to the Gulf. Elsewhere across the Mexican offshore waters, light to gentle winds and moderate seas, primarily in southerly swell, prevail. For the forecast, pulsing fresh to strong northerly winds are forecast in the Tehuantepec region through Sun, with seas building up to 7 or 8 ft. Afterwards, gentle to moderate winds are expected. Moderate to locally fresh NW winds and moderate seas are forecast off Baja California through Mon under the influence of a ridge. By Mon night into Tue, the pressure gradient may tighten enough between the ridge to the W and lower pressures inland Mexico to support moderate to fresh NW winds off the Baja California Peninsula. Fresh to strong SW winds may briefly develop in the northern Gulf of California Fri night ahead of a cold front approaching Baja California Norte, then moderate to fresh SW to W winds are expected through the upcoming weekend. Elsewhere, winds will be moderate or weaker with moderate seas through the next several days. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Recent scatterometer pass indicates moderate to fresh gap winds across the Gulf of Papagayo and downwind to near 89W. Seas are 4 to 6 ft with these winds. Farther east, gentle to moderate N winds and 3 to 4 ft seas are present in the Gulf of Panama and just south of the Azuero Peninsula to near 04N. Light to gentle winds and moderate seas dominate the remainder of the offshore forecast waters. Stronger winds are noted in scatterometer data offshore Colombia due to convective activity. For the forecast, fresh to locally strong gap winds are expected during the nighttime and early morning hours in the Papagayo area and downwind to about 89W through Thu. Toward the upcoming weekend, winds may increase to 30 kt with seas building to 8 or 9 ft in the Papagayo region as a stronger high pressure settles N of the area. Moderate northerly winds, occasionally fresh, are forecast in the Gulf of Panama throughout the forecast period, with stronger conditions most likely during the upcoming weekend. Light to gentle winds and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... A stationary front extends from 31N130W to 27N140W. Gentle to locally moderate N winds and moderate seas are behind the front. A band-like of multilayer clouds, associated with strong upper level winds, is noted south of the front entering the forecast waters near 21N140W. A 1020 mb high pressure center is ahead of the front located near 28N125W and extends a ridge across the remainder of the N waters, particularly N of 19N and W of 110W. The pressure gradient between the ridge and lower pressures in the vicinity of the ITCZ supports moderate to locally fresh winds in the trade wind zone, W of 120W. Seas of 5 to 7 ft are within these winds. Elsewhere, moderate or weaker winds and moderate seas are occurring. For the forecast, the front will move eastward across the waters N of 20N while dissipating by Fri. Gentle to locally moderate winds will follow the front along with seas 6 to 7 ft. The high pressure center located ahead of the front will dissipate on Thu, then, the high pressure following the front will take control of the weather pattern across the forecast waters over the next several days. $$ GR ########################### END OF MESSAGE SET ############################
