Turnagain Pass SNOTEL data.
Below are a few graphs showing how the snowpack on Turnagain Pass is faring. There are three
parameters measured: 1) accumulated precipitation, 2) snow water equivalent and 3) snow depth. These
graphs show this season to date compared to the long-term averages as well as last season.
This is simply the amount of rain or snow (water equivalent – if melted) that has fallen.
Surprisingly we are only ~83% of average for this season so far. Clearly, we have had A LOT of rain but not
much snow for this number to be so high.
Snow Water Equivalent (SWE), also called Snow Water Content:
This is the amount of water in the snowpack (if one was to melt the snow into water).
We are roughly 1/3 (38%) of normal amounts – this is quite low…
This is simply the height of the snowpack.
The snow depth sensor has only been in operation for 11 years now so the averages are not true “long-
term” averages (you need 30 years of data technically for that). However, compared to the last 10 years, we
are 39% of average. Like the SWE above, quite low and not surprising if you’ve been out at the Pass lately.
