Lake Tahoe Storm - Up to 5 Feet of Snow Forecast - 2010 November 19-21


Let it snow!  

Post up your storm photos/videos during/after this storm as snow accumulates on your decks, on top of your vehicles, on the slopes or in the backcountry and other areas plus any links to Trip Reports from this storm.  If possible list the location (city/resort/backcountry area + state) and elevation (if known) plus date & approximate time of the photos.  

How many feet of snow do you think we will receive from this storm?  What were the conditions like on your trip?

Five feet plus of snow is a promising start to the Lake Tahoe season.  

Here's hoping that the Tuesday Arctic cold front delivers a few more feet of snow.

This storm is sure gonna make the early season epic, especially if the weather here in Sacramento's been any indication. It was positively torrential at the Ski Dazzle fest on Saturday, meant some pretty good deals, though.

 

I'm going to be hitting Sugar Bowl on turkey day, can't wait! (Free lessons and rentals are great considering it'll be my GF's first time ever.)

post #5 of 9

What are the odds that the other lifts at Boreal besides Accelerator will open on Turkey Day?  I need to justify a 4:30 drive.

This latest November 2010 Lake Tahoe storm cycle delivered a lot to be thankful for with up to 108" of new snow.

Avalanche Hotline   530-587-3558

Today's Avalanche Advisory:

November 24th, 2010 at 06:30 AM

Near and above treeline on slopes steeper than 35 degrees, MODERATE avalanche danger exists on all aspects. Below treeline pockets of MODERATE avalanche danger exist on open slopes steeper than 35 degrees. Human-triggered avalanches are possible today.


Forecast Disscussion:

Yesterday's cold front left another 10-20 inches of new snow and mass of cold arctic air over the forecast area.


Avalanche Concerns:

Even though the wind slabs that formed yesterday have started to bond to the snow below them, the additional weight of a skier, boarder, snowmobiler, or snowshoe-er could still break these bonds today causing an avalanche. Avalanches involving these wind slabs could easily bury a person. The largest and most tender of these wind slabs will exist on the wind-loaded N-NE-E aspects and cross-loaded NW and SE aspects near and above treeline. Large, tender, newly formed cornices also reside above many of these slopes. These cornices should continue to break well away from their edges and could cause avalanches on the slopes below. As the winds shift to the NE and E today, they will start to move snow away from these wind slabs and cornices onto the SE-S-SW-W aspects. New, smaller wind slabs will start to form on these aspects near and above treeline. These new wind slabs could also be sensitive to human-triggering today. Some smaller, isolated wind slabs may still exist below treeline in open areas. Use clues like cornices, ripples, drifts, and blowing snow to determine where wind slabs exist today.
