Yosemite National Park has announced that it will close most of its areas due to the risk of flooding. The region saw massive snowfall which left more than 15 feet of snow in less than a month, closing Yosemite National Park last month. The Park will be closed until May 3 at the earliest, but may stay closed for longer, warns the National Park Service. The snowfall has also raised concerns over flooding as the snow melts. Yosemite National Park is no stranger to flood and drought cycles, in 2018 floodwaters covered Cook's Meadow in Yosemite Valley before years of drought took hold in much of California. However, with such vast amounts of snow still yet to melt, it raises concerns for increased flooding. Reports from San Joaquin and Owens valleys suggest that the heatwave expected this week could cause Sierra snowmelt and flooding in those areas. As part of the announced closure, immediate refunds will be given to those with lodging or campground reservations, which will be automatically canceled.
