North Rockies

Exercise caution on recently wind-loaded slopes and during periods of heavy snowfall or wind-loading.

• We are uncertain due to a limited number of field observations.

No avalanche activity has been reported since a significant avalanche cycle occurred last week.

If you are heading into the backcountry, please share your observations by posting a MIN.

Approximately 10 to 30 cm of dry, low-density snow overlies a thin crust in most areas at elevations of 2000 m and below. Below this crust, moist snow may persist, particularly at lower elevations.

A thicker crust buried earlier in March is present 50 to 80 cm below the surface at treeline and below. The early February crust is found at depths of 100 to 160 cm. These deeper layers are not currently a concern.

The remainder of the snowpack is generally well settled and bonded.

Monday Night
Partly cloudy. 2 to 5 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -9 °C.

Tuesday
Mostly cloudy. 1 to 5 cm of snow. 30 km/h southeast ridgetop wind. Treeline temperature -14 °C.

Wednesday
Mostly cloudy. 10 to 20 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -14 °C.

Thursday
Mix of sun and clouds. 1 to 3 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -13 °C.

• Be especially cautious as you transition into wind-affected terrain.
• Closely monitor how the new snow is bonding to the crust.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
