Much of the famed valley at California’s Yosemite National Park will be temporarily closed starting Friday due to a forecast of flooding as rising temperatures melt the Sierra Nevada’s massive snowpack. Park officials said Tuesday that the eastern section of Yosemite Valley will stay shut at least until May 3. Reservations for campgrounds and lodging in the eastern valley will automatically be canceled and refunded. Other sections including western Yosemite Valley will remain open. Spring weather is quickly melting huge amounts of snow that accumulated in mountains from a series of epic winter storms.
