"We are now 204% of average precipitation to this point in the water year (Oct 1 to Sept 30) and we have 92% of our average peak seasonal #Snow Water Equivalent (SWE)," the lab tweeted Sunday, noting the snow water equivalent refers to the amount of water that can be collected by melting the snowpack.
At least 7.5 feet of snow has fallen at the lab in the last week. Caltrans said about one inch an hour had fallen over Donner Summit from Friday through Sunday alone.
"It's still coming down hard out there!" the lab tweeted earlier on Saturday. "The snowpack is DEEP with ~10 feet (3 meters) of snow already on the ground!"
