All roads into Yosemite National Park were closed as of 5:00 p.m., PST, today, Friday, January 6th due to an approaching winter storm that is expected to cause heavy snowfall or rainfall, and possible flooding in and near the park.
“All roads leading into Yosemite Valley will close today at 5:00 pm in anticipation of a significant winter storm moving into the region early tomorrow morning, Saturday, January 7, 2017.
“There will be no visitor services available throughout the storm.
“Visitors intending to visit Yosemite National Park are highly encouraged to monitor weather reports and check road conditions before departing. These closures are being implemented to ensure the safety of park visitors and employees during the coming storm.”
As this San Francisco Chronicle story (video; photos) shows, a similar storm clobbered the park almost exactly 20 years-to-the-date ago, causing the Merced River which runs through Yosemite Valley to flood and create extensive damage that forced the park to remain closed until March.
The Los Angeles Times reports that the storm will bring a lot of snow at the higher elevations of the Sierra Nevada mountains, followed by very heavy rains.
Another winter weather system is expected to move through Northern California early next week.
