Well, now we've gone from fall to winter in much of the forecast area! Although the different weather forecast models don't agree on precipitation amounts, the one thing that is clear is that conditions in the alpine will be very winter-like.
Apologies for the late arrival of this week's summary.
The long-run on extended summer conditions has sadly come to an end. This weekend marks a distinct shift from Aug-tober to October, and to more typical fall weather and mountain conditions.
We are fully in a period of transition back to winter in the alpine now. Temps could be as low as -10 at 3500m and a dusting of snow today and Saturday, with the sun making an appearance again on Sunday and sticking around for most of next week.
Summer is back in the valleys and South faces up to treeline but in the High shady places there are some transitions going on.
Last weekends snow is to be expected to linger on the glaciers, North facing alpine and probably just to the West and East of North in the alpine. Even in the trees in Kananaskis country this week it was slow to leave shaded glades below treeline and there were remnant small cornice above 2800m.
The left over issues will be some wet alpine rock, morning verglas, the new small cornices and the possibility of weak skinny bridges over crevasses.
The story of this September long weekend in the Rockies and Eastern Columbia's is the abrupt arrival of fall!
This past week was great overall with good freezes, dry rock and lots of sun.
People are getting out on all of the main objectives and reporting great conditions for this time of year. Usually by late August there are brown streaks on all of the ice faces and gullies with lots of rockfall. This year is a bit different due to better snow coverage.
The last weeks have provided a wild difference in conditions depending on where you are on the Coast. It really couldn't be more different between South and North Coasts. I've been working in the Cambrian Range near Stewart where it feels like it hasn't stopped raining in August yet! Roads are washed out, creeks are flooded, glaciers and snow are melting rapidly and I've been wearing long underwear every day. Meanwhile on the South Coast the heat has been record breaking! It's hard to believe it's all one province sometimes.
It continues to be an alpine summer to remember with good conditions reported in all zones and for all mountain pursuits. There is a caveat, though: depending on the weather, not every activity or route is in shape every day.
WEATHER
Last week ended with some stormy weather, which gave us precipitation in the form of snow at higher elevations. As we entered this week, the hot weather returned, although there was some electrical activity in the afternoons and evenings.
There have seldom been such widespread good conditions for August in recent memory. In the past week, I have climbed glacier routes, alpine rock, and been hiking. Everything was in good shape.
WEATHER
The only fly in the ointment has been some fickle weather. Although there has been some sun and warmth, especially at lower elevations, there have also been showers and low freezing levels which have given dustings of snow to the peaks.
The coming week looks promising for the most part.
