Avalanche problem #1 : Storm slab

On Monday, as storm snow accumulates on the crusted surface, the chance of a human avalanche triggering will increase in the alpine and at treeline on all aspects. Depending on the amount of snow, it will also be possible for natural avalanches to occur.

Avalanche activity

No new avalanche was observed or reported recently.  Please share your observations at info@avalanchequebec.ca, on the Avalanche Canada’s Mountain Information Network or with this online form.

Snowpack

In the alpine and at the treeline, following the rains and the rain of the last days, the temperatures which became negative again contributed to the formation of a rind of generalized freezing on the surface. Below the treeline, this crust of freeze probably does not exist at the lowest elevations because of the absence of frost for 2 days.

Weather forecast

A storm will hit Chic-Chocs and have the potential to leave between 15 and 25 cm of snow in the mountains on Monday. The precipitation could then continue until Tuesday evening. This system will keep temperatures slightly below freezing with strong winds from NE Monday turning to N Tuesday.
