LEMOORE, Calif. (AP) — Park officials are temporarily closing much of the famed Yosemite Valley due to a forecast of flooding as rising temperatures are expected to melt the massive snowpack accumulated in California’s mountains from a series of winter storms.

Farmland in the Tulare Lake Basin is submerged in water in Corcoran, Calif., Thursday, April 20, 2023, after more than a dozen atmospheric rivers dumped record-setting rain and snowfall. Residents in rural communities in the heart of the state are facing the prospect of being marooned by rising rivers or flooded out.

Yosemite National Park announced Tuesday on social media that most of the valley will close starting late Friday and stay closed at least until May 3. Reservations for campgrounds and lodging in the eastern Yosemite Valley will automatically be canceled and refunded.

Other areas including western Yosemite Valley will remain open, officials said.

California’s state climatologist Michael Anderson warned this week that rising temperatures will speed up the snowmelt and double the amount of water flowing into some of the state’s reservoirs. Water managers will determine whether they need to release more water from reservoirs but residential communities are not expected to see immediate flooding due to the warming trend, he said.
