Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Tue Jun 9 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. ...SPECIAL FEATURES... Post-Tropical Cyclone Boris has dissipated in recent hours across the interior of western Guerrero, Mexico. Scattered showers continue across much of the interior highlands of the area. Mostly W to SW winds less than 20 kt currently prevail across the area coastal waters. However, large cross-equatorial S-SW swell continues to move into the area coastal waters, generating large and powerful surf along the coasts. Tropical Storm Cristina is centered near 12.7N 87.8W at 2100 UTC, drifting W-NW at 1 kt. Estimated minimum central pressure is 1006 mb. Maximum sustained wind speed is 35 kt with gusts to 45 kt. Peak seas are currently around 14 ft or 4 m. Strong northeasterly vertical wind shear continues to plague Cristina, limiting intensification. Scattered to numerous moderate to strong convection is noted N of 07.5N between 86W and 90W. Cristina is forecast to meander near the coast today as it remains under hostile upper level conditions, and is expected to turn toward the northwest and west- northwest through midweek. On the forecast track, Cristina should move near or along the coast of Nicaragua, the Gulf of Fonseca, and El Salvador during the next couple of days. Little change in strength is forecast today, followed by some weakening through midweek. Heavy rainfall associated with Cristina will impact coastal portions of Central America through Thursday. This rainfall may produce life- threatening flooding and mudslides, especially in areas of steep terrain. In addition, large cross-equatorial S-SW swell is slowly subsiding across the regional waters this morning, but will continue to produce large and powerful surf along the southern Mexican coast through Wed morning.

A monsoon trough extends from 14N92W to 16N95W to 09N111W to 08.5N127W. The ITCZ extends from 08.5N127W to 10N138W. Other than the convection described above associated with Cristina, scattered moderate convection is noted from 01.5N to 07N between 80W and 92W, and from 04N to 08N W of 128W. Scattered moderate isolated strong convection is noted from 08N to 17N between 93W and 104W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A broad ridge extends from a 1030 mb high well NE of the Hawaiian Islands near 34N146W southeastward to W of the Revillagigedo Islands near 20N120W. Broad low pressure extends from southern California SSE into Baja California Norte. This pattern is supporting gentle to moderate N-NW winds offshore of Baja California Norte, with fresh winds across the outer waters NW of Isla Guadalupe. Gentle to locally moderate NW to N winds prevail offshore of Baja California Sur. NW winds near the coast at Cabo San Lucas continue to wrap round the southern end of the peninsula, resulting in fresh westerly winds near the southern tip of Baja California, while a few areas of moderate W gap winds prevail inside the southern Gulf of California. Seas of 7 to 9 ft in merging N and S-SW swell continue across the Baja waters, except to 10 ft N through W of Isla Guadalupe. Gentle S winds are in the northern Gulf of California N of 30N, where seas are 1-2 ft. light and variable winds prevail across the central Gulf. Strong southerly swell moving into the entrance of the Gulf is producing seas of 4-7 ft in southern portions. Moderate to locally fresh NW to W winds prevail elsewhere from Cabo Corrientes to offshore of Tehuantepec, where seas are 8-13 ft in large, cross- equatorial S-SW swell. Scattered showers and isolated thunderstorms are seen across the waters N of 13N between Tehuantepec and Michoacan. For the forecast, a broad surface ridge extending into the waters W of the Revillagigedo Islands will weaken and shift Wed through the upcoming weekend, as broad low pressure along the coast of southern California drifts westward. This will lead to light to gentle winds across the waters of Baja California, and moderate to locally fresh SW to S winds inside the Gulf of California. Afternoon and evening winds will pulse moderate to locally fresh near the coast Fri through the weekend. Northerly swell will merge with strong S swell moving through the Baja waters this afternoon through Wed to maintain rough seas before subsiding. Gentle to locally moderate NW to W winds will dominate the waters between Cabo Corrientes and Tehunatepec through Fri, then weaken into the weekend. large cross-equatorial S-SW swell dominating those waters will gradually subside tonight through Wed. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Please see the Special Features section for details on Tropical Storm Cristina, just offshore of extreme NW Nicaragua. Cristina remains in a hostile upper-level environment and it meandering this afternoon. Numerous moderate to strong convection continues across the waters N of 10N to the vicinity of Cristina, between the coast of Nicaragua and the offshore waters of Guatemala, fueled by fresh to locally strong SW to W monsoonal winds well to the south of Cristina. Large cross equatorial S-SW swell continues to dominate the regional seas this afternoon, producing seas of 8 to 13 ft across most of the area W of 86W, and 7 to 10 ft E of 86W. Moderate to locally fresh SE winds extend from coastal Ecuador through the Galapagos Islands, while winds and light and variable elsewhere E of 85W. For the forecast, Tropical Storm Cristina will meander this evening, then begin to move W-NW through Wed, reaching39 near 12.8N 88.2W tonight, near 13.0N 88.8W Wed afternoon, and then inland near 13.5N 89.2W Wed night. Slight strengthening is possible. Heavy rainfall is expected across coastal portions of Nicaragua and El Salvador and may produce life-threatening flooding and mudslides, especially in areas of steep terrain. Otherwise, large cross-equatorial S-SW swell will continue to impact the regional this afternoon through Wed before subsiding, resulting in large and powerful surf along the coasts. Refer to your local meteorological information for more details on the surf zone and beach impacts. Gentle to moderate winds and moderate seas will prevail across the offshore waters Thu into the weekend. ...REMAINDER OF THE AREA... The 1012 mb Remnant Low of Amanda is analyzed near 10.5N140.5W. Small clusters of moderate convection are noted within 120 nm across the N and NE semicircle. Fresh to strong NE winds are found within 210 nm in the N and NW semicircle, with seas of 7-9 ft are found from 09N to 20N between 120W and 140W. Otherwise, a broad ridge extends from a 1030 mb high well NE of the Hawaiian Islands near 34N146W southeastward to W of the Revillagigedo Islands. Moderate to fresh N to NE winds are found elsewhere S of the ridge to 10N and W of 120W. Seas are 6-9 ft elsewhere N of 10N and W of 110W, and 5 to 6 ft N of 26N and W of 130W. Merging N and S swell prevail across the waters N of 20N and E of 125W, producing seas of 8 to 10 ft. For the forecast, the Remnant Low of Amanda will continue W of 140W and weaken further. Moderate to locally fresh trades will continue to dominate the waters N of 10N and W of 120W under the broad ridge through Wed, then will weaken as the high begins to shift NE through the end of the week. Winds will be moderate or weaker elsewhere through tonight through Wed. Meanwhile, northerly swell in the N-central waters will produce seas of 7-10 ft for the next several days, merging with large cross- equatorial southerly swell. Moderate seas will dominate the open waters by the end of the week into the upcoming weekend.
