Boris weakened after moving inland over southern Mexico, but its outer bands were still producing rain, gusty winds, and rough surf along the Pacific coast, including the Jalisco coast.
The storm made landfall early Tuesday between Guerrero and Oaxaca. In its early-morning weather bulletin, Mexico’s weather service said Boris came ashore with sustained winds of 65 km/h, gusts to 85 km/h, and movement toward the north-northwest.
By 9 a.m., the system had decayed to a remnant low over southern Mexico, according to the latest public advisory from the U.S. National Hurricane Center. The center was about 105 kilometers east of Acapulco, with sustained winds near 45 km/h, and no coastal watches or warnings remained in effect.
Jalisco still has rain and surf concerns
The weakening did not end the weather risk for Jalisco. Federal forecasters had called for very heavy rain in southern Jalisco, with 50 to 75 millimeters possible, along with 40 to 60 km/h coastal gusts and 2– to 3-meter surf along the Jalisco coast.
Sergio Ramírez López, director of Jalisco’s state civil protection agency, said “Boris does not represent a storm risk for Jalisco,” while warning that the state had issued rain alerts for coastal and mountain regions. Those alerts are centered on the Costa Sur, the Costa Norte, and the Sierra Occidental, with storms more likely in the afternoon and evening.
A state civil protection bulletin for Costa Sur and Costa-Sierra Occidental also flagged possible stream rises in the Marabasco, Purificación, and Tomatlán basins. It warned of saturated soil, landslides, rockfalls, and possible debris on Federal Highways 200 and 80, the kind of road risk that can show up quickly after repeated rain.
What Puerto Vallarta should watch today
The worst rain forecasts are aimed farther south and east of Puerto Vallarta. Still, the local watch is not over. Banderas Bay, beaches near Cabo Corrientes, and open-coast routes toward Tomatlán can feel the aftereffects through choppy water, sudden squalls, and wet mountain roads.
Beachgoers should follow posted flags and avoid entering the water during rough surf. Small-boat operators and tour companies should check port and civil protection instructions before leaving shore. Drivers heading south on Highway 200 should watch for standing water, rocks, and mud, and expect low visibility during heavier showers.
The update comes during the early stretch of Puerto Vallarta hurricane season, when storms do not need a direct hit to cause trouble. Today’s Puerto Vallarta weather report already had rain in the local forecast, with Boris adding another reason to keep an eye on hillsides, arroyos, and the bay.
Forecasters expect Boris to dissipate over the mountains of southern Mexico later today or tonight.
