ACMG Mountain Conditions Report for the Columbia and Rockies Mountains July 5

Well summer is finally back in Canada, along with the mosquitos and no-seeums. This weeks cool temps and precipitation has brought snow across most of the Kootenays and Rocky Mountains above 2500m. I would expect on sunny aspects that it is disappearing fast. The weekend is looking hot with possible unsettled weather on Friday night into Saturday and isolated thunderstorms. With things warming up and melting out I would be anticipating rockfall, surface snow avalanches and whats left of cornices to be week.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. June 28st, 2018

As we approach the Canada Day long weekend, we also approach an unsettled week of weather. Many forecasts are calling for rain through the weekend with snow at higher elevations, and way up high one could assume there could be some concern about smaller storm/wind slabs in the short term, and loose wet avalanches in gully features.

ACMG Mountain Conditions Summary for the Coast Mountains. June 28th 2018

As I write this the coastal alpine peaks are enshrouded in cloud and it’s below freezing on the summits. The weather the past week has been unsettled, with fresh snow in the alpine making for tricky conditions. Photos an experienced friend showed me from a failed attempt on Mt Tantalus on Tuesday looked like January, with lots of rime ice. He also noted that the crevasses were starting to open up since the previous week, but the bergshrunds were still in good condition.

In the North Shore Mountains there is still a lot of compact above 1200m, although very little below this.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. June 21st, 2018

The official start to summer has many places in the Rockies and Columbia's under a thunderstorm watch as unsettled showery weather rolls in for the next couple days. Sunday looks drier, with more unsettled weather Monday before things improve. Keep a close eye on the sky for afternoon thunderstorm development and bring what you need for a quick retreat if necessary.

ACMG Mountain Conditions Summary for the Coast Mountains. June 21st 2018

Junuary on the coast has ended. Some intense the past couple of days has resulted in isothermal snow conditions in the alpine, poor freezes, and a slab avalanche cycle within recent (last week) and old snow layers up to Size 3. Several guides have turned around on common objectives in the Sea to Sky corridor for this reason along with the threat of falling cornices.

Many alpine rock objectives have now come into shape, with good conditions being reported in areas such as the Tantalus Range.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. June 15th, 2018

The fabulous spring mountain conditions have been interrupted by the snow, rain and wind of the past week. In Glacier Park, reports of up to 50cm of new snow having fallen above treeline over the past few days. Similar amounts in the Nakusp region at treeline and I would suspect that is representative of conditions throughout most of the Columbia mtns alpine.

ACMG Mountain Conditions Summary for the Coast Mountains. June 14th 2018

The weather on the coast has been unsettled since last weekend, with 30-40cm of new snow accumulated in the alpine on Blackcomb Mountain. The new snow was wet and sluffing today, as you would expect this time of year. No slab avalanche activity has been reported, although it is possible with that much new snow. The new snow fell as rain below treeline, which has helped to melt away last winters snow lingering on the trails.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. June 8th, 2018

It's been a great week for being up high in the mountains of Interior BC and the Rockies. Alpine routes in Rogers Pass have been getting traffic including shadier mid-elevation routes like MacDonald NW ridge. Mixed routes in the Rockies have been in good condition with great overnight freezes and easy travel on settled spring snow. Glacier coverage continues to make for generally uncomplicated travel, although as always at this time of the year caution is required in the way of roping up and monitoring snow depth vigilantly with a probe.

ACMG Mountain Conditions Summary for the Coast Mountains issued June 7th 2018

Conditions are currently suitable for both alpine climbing and skiing in the Coast Mountains, although you have to do your research and pick your objectives carefully to find out where the snow still remains. You can still expect to run into significant snow patches as low as 1300m (depending on aspect, tree cover and sun exposure), then continuous snow before you reach the alpine.
