More Snow Coming to the Cascades

If you were thinking that now that spring is here, you should put your skis away--don't do it.   The mountain snowpack is still healthy and more is coming on Thursday.

Regarding our current snowpack, here is the current snow depth at Stampede Pass, at 4000 ft in the central Cascades.  Holding in there at around 85 inches, while the snow water equivalent in the snowpack has been rising.  Why?  Because we have had some warmer periods with rain and melt, with the water running into the snowpack and refreezing.  That is how Cascade concrete is made!


But go higher in the Cascades, say at Paradise Ranger Station (5500 ft) and the story is different...the snow depth has continued to rise.  Why?  Because there was less rain and more snow at that elevation.


And now the fun part.  Here is the 72hr snowfall total from this morning's run of the UW WRF model.  Up to several feet in the Washington Cascades!   Southern BC (including Whistler) will get hit hard. Most of the snow will be on Thursday.


We have a very healthy snowpack and the water situation looks very good for this summer.  Here is the latest percent of normal:  most areas are 100% of normal or more.
