“At this point, we still have four to five months into the snow season and the typical wet season,” said Andrew Schwartz, principal scientist at the Central Sierra Snow Lab. That means we’re scoring a touchdown in. At this point, we’re still three quarters away and a lot can happen.”

Scientists Say Extra Winter Precipitation Was Needed to Overcome California’s Drought

Schwartz said last year’s winter season got off to a good start with record-breaking mountain snowfall in December. “But from January he didn’t get any rain through March, and we didn’t get as much rain as we wanted in that period.”

But even average snowfall is not enough to keep the region out of drought.

“Right now, realistically, we need a day’s worth of winter rain,” Schwartz said. “So it’s not going to happen in a year. We’d probably be at least three or four times above average before we really talk about coming out of the drought.”

During the average season, the lab sees 30 feet of snow. An extra season’s worth of snow means 60 feet in a year. It’s a very “high job to take on,” he said.
