ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. September 10, 2021.

A normal autumn pattern for weather, conditions, and hazards looks like it will be in play for the next week.

Crisp days with bluebird skies over much (if not all) of the past week will change to more variable weather in all areas of the Rockies and Columbias. There will be some precipitation over the weekend, a couple nice days at the beginning of the week, and then models are showing a significant pulse of moisture on Wednesday. Keep an eye on the forecasts to see if the timing or intensity changes.

Regional Summary for Rockies and Columbia Mountains September 2, 2021

The first signs of autumn arrived in Canmore this week, with some leaves already turning yellow. That said, it looks like we’ll be returning to more seasonal temperatures and conditions after a particularly wintery week in the mountains.

The forecast is generally good for the long weekend, except for some isolated rain expected in more northern regions. It should be relatively warm, with freezing levels climbing up to ~3000m during daytime highs.

We seem to be slowing easing into early Autumn in the Rockies and Columbias with shortening days and some relatively cooler temperatures. It is a slightly awkward time for choosing objectives in the mountains as there are numerous "problems/hazards" but they vary some widely across terrain features and across the ranges.

1. Verglas The snow from earlier this week is "mostly" gone at treeline and the lower alpine but I was still seeing verglas in shady places around 2500m yesterday at O'Hara. Expect this throughout the alpine as a possibility.

Regional Summary For Interior and Rocky Mountains Aug 20, 2021

Weather: Current forecasts are showing 10-20mm of rain in the Rockies and Columbias over the weekend with freezing levels near 3000m. There will likely be some snow flurries at those higher elevations. More stable weather is in the forecast starting Monday. The good news over the weekend is that the fire smoke forecast is mainly clear for all of these regions, probably returning next week.

Regional Summary For Interior and Rocky Mountains Aug 12, 2021

Over all the Alpine is dryer and warmer then the average summer. What this means is there is more bare ice on the glaciers and there are more rockfall events occurring.


This summer has been dry and hot. This trend will continue through the weekend but there is some precipitation in the forecast for early next week in the Interior and Rocky Mountains. Models are showing up to 12 mm of rain in the Interior and 6 mm in the Rockies starting on Monday, with temps dropping we may see some snow at high elevations, although it will likely not last.


ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. August 5, 2021

After another hot, dry and smoky week in the Rockies and Columbia Mountains, some unsettled weather is on the horizon for most of BC and the Rockies especially on Friday and Sunday. Forecast precipitation amounts vary considerably over the region so keep checking local conditions, but expect some showers or thundershowers and slightly cooler temperatures before a ridge of high pressure is slated to start building again early next week.

A minor change may be in the works in the next week, with some showers forecast. Long term modelling shows more sustained precipitation starting in a week or so - we can keep our fingers crossed that we will get some "bad" weather in August, but I'm not holding my breath.

Heat and smoke have been the norm most places, and I'm not sure there is enough rain in the forecast to change that much.

ACMG Mountain Conditions Summary for the Coast Ranges - July 30, 2021

As a habitually suspicious species, we humans tend to feel "the grass is always greener"whenever we consider our own situation in life. But I'm suggesting that, at least as far as mountain conditions go, that it simply doesn't get any better than what we've got in our backyard right now. I've spent most of the last month in the Boundary Range around Stewart and, having just done a 3-day smash and grab in the Tantalus Range, I can offer a broad perspective on Coastal conditions.

ACMG Mountain Conditions Summary for the Rockies and Columbia Mountains. July 22, 2021


It was hot again this past week which continued to melt away any snow up high, and overall has made the ice faces look like mid August, not mid July. Having said this, a report from the Mt. Alberta hut near the Columbia Icefields this AM (~2750m) said there was 5cm fresh snow at the hut, was cold today, and that snow wasn't really melting.
