Yet another low with a big impact. Not only from the amount of snow but more importantly how many parts of the Province felt the winds.  Thanks for the shot Nicole.

If the instruments are accurate it is obvious that there is much variability. Which also means that the wind is blowing the snow in many directions. We all know that the mountains shift the wind around but it would be better information if directions were more accurate.

Another topic related to this is how well are we documenting the wind in association to wind transport??

Boxing the compass is a term from the sea, but perhaps as mountain folk we should embrace its accuracy.
