Yosemite National Park Braces for Flooding and Summer Setbacks.

Warmer-than-average weather is causing increased snowmelt in the Sierra, leading to potential flooding on several waterways including the Merced River near Yosemite National Park. The river could reach flood stage as early as Monday evening, with forecasters projecting water levels to keep rising past flood stage through the end of this week. Some campgrounds in the park are already closed, and more closures are possible in the coming days. Anyone with reservations in Yosemite National Park should be aware of likely closures this week due to issues with runoff, which may occur at any point between now and late June.
