ACMG Mountain Conditions Summary for the Coast Mountains June 20th 2019

The dry alpine rock with warm and sunny weather on the coast is temporarily on hold. Last night in the Sea to Sky Corridor we had a dusting of new snow down to around 1800m, with more towards the north on the Duffey Lake Road with what looked like about 10cm in the alpine (photo attached). Expect increased rockfall as the new snow melts, which will probably one of the biggest hazards this weekend. Cornices lingering from the winter and also still out there and collapsing, which I witnessed a couple of times in the past week.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains June 20th, 2019

It looks to be a soggy Thursday night and Friday day in the Rockies but possibly staying a little drier in the Columbias. Observations from the Rockies near the divide currently show around 10-20 cm of recent snow above 2000m up by the Columbia Icefields and maybe 5-10 new snow at around 2100m around Lake Louise/Lake O'Hara. Assume much more than that above 3000m.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. June 14, 2019

After a few days of unsettled weather, the weekend is looking pretty good for getting out in the mountains! Saturday and Sunday are forecast to be mostly sunny with a small chance of late day thundershowers. Saturday night looks both cool and clear which should help snow travel conditions on Sunday morning if you get up early enough. Monday ushers in a week of unsettled cool and showery weather according to the current long range forecasts.

ACMG Mountain Conditions Summary for the Coast Mountains. June 6, 2019

Alpine climbing season has cooled from last week...for the better.

Weather
Wet and cooler temperatures have been the pattern of the week and leading through the coming weekend. Far more typical conditions to be expected for this time of year. Generally, the system has been broken with periods of sun or strong precip. A dusting of new snow to 1900m has in most places melted but might still be found in some deep, dark, high places.

It is that time of year again to start up the MCR summary machine, and we will keep it running through the summer and into the late fall.

Avalanches and cornice collapses in all regions are still the biggest hazards during this transition period, and should be monitored as conditions vary dramatically through the day. Avalanche gear while skiing or climbing should still be worn in avalanche terrain that still has snow on it, even though our minds are shifting to summer.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. November 9th, 2018

CONDITIONS
This past week has been wintery in the west, with overnight lows in the alpine nearing -20°C and little storms bringing in small but constant amounts of snow in the Rockies and Columbia mountain ranges. In the Rockies, treeline snow depths are now above threshold for avalanches (50 cm+) and in the Rogers Pass area you can expect up to double that. Alpine snow depths are over a meter in the Rockies and over 150 cm around Rogers Pass.
