Avalanche Forecast
Regions: Banff Yoho Kootenay.
Perhaps a minor refresh to the conditions by Wednesday, with up to 10 cm of new snow expected at higher elevations. Check the bond of any new snow to the underlying crust and watch for any wind drifted snow at the higher elevations.
Weather Forecast
A cold front crossing the region on Tuesday afternoon/evening will leave behind 5-10 cm of new snow at high elevations and unstable air for Wednesday. The freezing level is expected to fall slightly to 1600 m on Tuesday in the wake of the cold front. Cool, unstable air will remain for the next few days.
Snowpack Summary
Surface crusts exist on all aspects below 2300m and high into the alpine on solar aspects, now with a few cm of new snow overnight. High N aspects still hold dry powder and some wind effect on lee slopes. Deterioration of crusts has been occurring almost daily, with the extent of the breakdown depending on solar radiation and freezing levels.
Avalanche Summary
No avalanches observed or reported today.
