NOAA just upgraded the incoming storm headed to California.

NOAA is now calling for 4-8 FEET (48-96″) of snow above 7,000′ and they’ve issued a Winter Storm Warning.

We don’t even really know what to say about this insane forecast so we’ll let NOAA do the talking.

* WHAT...Heavy snow expected. 3-Day storm total snow accumulation of 2 to 4 feet, 
except 4 to 8 feet above 7000 feet expected. Winds gusting as high as 60 mph 
with gusts over 140 mph for the Sierra ridges. Periods of white-out conditions 
are likely.

“Well, here we go again. Another storm is expected to move into the Sierra Monday bringing steady, and eventually heavy snow. This will be a marathon rather than a sprint in terms of snow accumulation with several wet feet of new snow expected over top of a drier layer of powdery snow through early Thursday.

Travel will be tough, and possibly impossible at times, through the Sierra with no clear break in snowfall once this begins. Expect to add potentially several hours to your travel time over Sierra passes; periods of white-out conditions are anticipated and road closures will be possible.

This new snow load coupled with expected wind may result in unstable slope conditions with the potential for avalanches and roofalanches – do NOT linger under eaves of buildings that have a large quantity of snow on its roof.

Impacts from this storm will likely be cumulative, meaning that they will increase through the duration of the event.

Elsewhere, not much precipitation is expected, but it will be windy.” – NOAA Reno, NV today

NOAA has also issued an Avalanche Warning with this forecast storm.

* AVALANCHE DANGER...Periods of HIGH avalanche danger may occur from Monday 
evening through Thursday morning.

Tahoe is on track for a top 3 best snowfall season in recorded history with 515″ having already fallen on Squaw Valley.  

Squaw Valley averages 450″ of snowfall per year meaning that they are already 65″ past our annual snowfall and it’s not even March yet…

The Lake Tahoe snowpack is currently sitting at 170% of average to date and is the 2nd deepest in the nation (only Mammoth is deeper).

Squaw Valley has already seen its largest February snowfall total in history with 254″ having already fallen in February and much more on the way before the month is over.

Lake Tahoe even rose 12″ since February which is about 40 billion gallons of water.

This is the year to be in Tahoe…
