Kootenay Boundary

New surface instabilities cover a stable snowpack.

Watch for snow amounts, and wind loading.

Back off steep terrain if signs of instability are observed.

• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.

Moderate

• We are uncertain whether the wind will be enough to form new wind slabs.

Several dry loose and wet loose avalanches were reported on Monday up to size 1.5 both natural and rider triggered.

Also on Monday, a few natural small size 1 wind slabs were reported.

Scattered flurries add 5 cm to a recent 15 to 20 cm of new snow. South-facing aspects have developed two solar crusts near the surface; wind-affected surfaces are found elsewhere.

Below this, a crust of variable thickness can be found in most locations and is down 20 to 50 cm and has been the bed surface for most recent avalanche activity.

The mid and lower snowpack is well settled and strong in most areas.
