Another 1-2 feet of snow set to hit Lake Tahoe
Though South Shore residents have been enjoying a stretch of bluebird skies, a storm is scheduled to hit this weekend to kick off what could be another wet winter month ahead.
“We are looking for a storm to come in around Saturday afternoon through Sunday afternoon. It’s a pretty decent cold storm. We are expecting 1 to 2 feet of snow above 7,000 feet with potentially up to 10 to 18 inches below that,” said Zach Tolby, forecaster with the National Weather Service (NWS) in Reno.
Temperatures on Saturday will range from 27 to 42 degrees, and drop further on Sunday to between 16 and 32 degrees.
“After the storm goes past this weekend, we will get some dry weather probably most of next week,” said Tolby, “and then it does look like there are some indications that we could get back into a wet pattern closer to the middle of March.”
Though forecasts more than a week out are difficult to determine, Tolby noted that the NWS is able to examine the probability of atmospheric rivers hitting the area.
“Those really moist, subtropical storms that we’ve been getting a lot of this year,” said Tolby. “There are some pretty good indications that going into 10 days out we could go into a fairly wet pattern with some atmospheric river storms moving into the area.”
This year has already brought an above average number of atmospheric river storms to the Lake Tahoe.
“Usually we get a couple a year, maybe three to five, and that is our overall average, but in California and the Sierra we have pretty wide swings. Sometimes we will get zero or one, and then this year we have gotten 10 or 12,” said Tolby.
And that has translated into some serious snowpack for the Sierra Nevada.
Data collected by the California Department of Water Resources on March 1 from its 98 stations scattered throughout the mountain range revealed that the water content of the northern Sierra snowpack — the depth of water that would result if the entire snowpack melted — is 39.2 inches or 159 percent of the multi-decade average.
Heavenly Mountain Resort has recorded 556 inches of snow over the season, Kirkwood Mountain Resort has tallied 578 inches, and Sierra-at-Tahoe has logged 492 inches.
As of March 2, the lake level is at 6,226.74 feet — 3.74 feet about the natural rim. Since Oct. 1, Lake Tahoe has risen roughly 3.5 feet and is 2.36 feet shy of its federal legal limit.
State climatologist Michael Anderson describes this winter as “historic” — but it’s not over yet.
Though January is typically the winter month with the most snow, March has a history of coming through to salvage dry winters.
The term “Miracle March” was coined in 1991 during what was on course to be the driest winter on record after a seven-year drought.
According to Tribune archives, ski resorts were preparing to pack up shop when a series of snowstorm starting on March 1 delivered 50 inches of snow, and it kept coming for the rest of the month.
On March 26, 1991, Tribune staff writer Jennifer Coverdale wrote, “March snowfall won’t solve the drought, but it is bringing the Lake Tahoe Basin out of ‘catastrophic’ conditions that threaten to prevent runoff into regional watersheds, according to U.S. Soil Conservation Service snow surveyors.”
Similarly, even after an above-average winter and perhaps even a “Miracle March” ahead, the statewide drought is not yet over.
“Many Californians continue to experience the effects of drought, and some Central Valley communities still depend on water tanks and bottled water,” the California Department of Water Resources said in a release on Wednesday.
“Groundwater — the source of at least a third of the supplies Californians use — will take much more than even an historically wet water year to be replenished in many areas.”
The U.S. Drought Monitor, a weekly federal report, stated last Thursday that 49 percent of California is no longer in a drought, including Lake Tahoe and every Northern California county.
Nevertheless, Gov. Jerry Brown is not likely to make a decision on whether to amend or rescind California’s emergency drought declaration — which has been in effect since Jan. 2014 — until the winter season is over.
