Cooler temps for the next couple days = all about timing. Expect firm snow in the morning and corn in the afternoon.

Snow is disappearing quickly in the park, south facing ice climbs have fallen down. Come get that last bits of winter while it lasts.

Timing or intensity of solar radiation is uncertain

Problems

Loose Wet

An icon showing Loose Wet

Wet loose activity will increase with day time warming. Pay close attention to steep rocky solar slopes.

  • Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.

Likelihood

Likely

Expected Size

1 - 3

Cornices

An icon showing Cornices

Sustained high FL this week is weakening cornices. A cornice drop can be hazardous on its own, or also has the potential to trigger larger avalanches. 

  • Cornices become weak with daytime heating.
  • Give cornices a wide berth when travelling on or below ridges.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3
