Yosemite Valley lodgings, campgrounds and roads will close 5 p.m. Friday ahead of a heavy storm forecast for the area that could cause flooding. Overnight and day visitors will have to leave the valley at that time.

The Los Angeles Times reported that national park officials announced Thursday (April 5) that campground and lodging reservations have been canceled for Friday and Saturday evenings.

In addition, roads into the valley — Big Oak Flat Road (Highway 120) at the Forest Road Junction and Wawona Road (Highway 41) at Chinquapin and along Highway 140 — also will close.

The National Weather Service forecast 3 to 4 inches of precipitation for Yosemite Valley over the weekend, with the heaviest rain and snow falling Friday and Saturday.

The heavy rainfall plus snow melt could create “excess runoff and bring a threat of localized flash flooding, mud slides, rock slides and debris flows,” the agency said.
