North Rockies

Expect the upper snowpack to deteriorate and become reactive with daytime warming and solar effects.

No recent avalanche activity has been reported.

Despite the low danger rating, the likelihood of triggering an avalanche will likely increase throughout the day with warming and strong solar radiation expected.

Please consider submitting to the Mountain Information Network if you are getting out in the backcountry.

Variable amounts of recent snow have buried various melt-freeze crusts, existing on all but north-facing alpine terrain.

Anticipate a weak, breakable surface crust to form overnight at lower elevations and on all south-facing terrain. North-facing terrain at the treeline and above should remain largely dry and powdery.

Surface snow will deteriorate and become moist throughout the day with daytime warming and strong solar effects.

• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
• Closely monitor how the new snow is bonding to the crust.
• Be alert to conditions that change with elevation and sun exposure.
