Also, on Saturday and Sunday, numerous small (size 1-1.5) natural wet loose avalanches were reported on steep slopes facing the sun.This region is data sparse.

Sun and rising freezing levels will turn snow moist during the day, warm temperatures overnight will likely prevent a strong crust from forming.Where dry snow prevails. 15 to 50 cm of recent storm snow sits on moist snow around treeline or likely on a crust in the alpine. In some areas east of Nakusp, small, weak facets have been seen on the crust.The mid and lower snowpack is well settled and strong.Check out this Conditions Update for tips on managing the current spring conditions.
