T360 Prime Evening Time Apres Ski under construct @ 9:15 P.M.

The problem for most Regional and/or Urban Ski/Board people
who have not Skied in the last 72 Hours, is that their frame of
Weather Reference will be skewed by all the Rain they saw, even if
they only live as far away as St. Jovite.

That did not happen the same way on Tremblant’s Open Alpine Snow
Sport Mountain Elevations. No doubt it was damp, humid, misty, sleety,
foggy, freezy and generally wet, but it never teamed rain on the
Mountain anywhere that we are aware. That does not mean it might not
have happened, it’s just that we were not where-ever, when-ever it might
have. There was some Freezing Rain, but we cover that separately, below.

The evidence to support that is this....

Snow in the Trees.(**)


(**) Snow in the trees is uninsulated, any source of heat above Zero C will attack
Snow from 360 Exterior degrees and melt it very quickly. It does not have the benefit
of any base acting under it as an ambient Refrigerant the way a Trail has the Frost in
the Ground Underneath to help stabilize its surface.

Consequently, the presence of Snow in the trees is confirmation of the
absence of any Plus Value Temps where that Snow in the trees still exists.

There are also some sectors of Ice in the trees, indicating Freezing Rain fell
but Freezing Rain is far less of an issue on the runs of a Ski Mountain than
regular rain because on surfaces it freezes on contact with, it is not either
destructive or corrosive the way running Rainwater is. Furthermore on Trails,
it all breaks up as mostly fine crystalline particles under 12,000 Lbs of a Pinroth
BR350 Groomer with a Carbide Toothed High RPM Tiller slung out behind.

On top of that, it did Snow last night as the temps dropped, so there is a small,
but perceptible amount of Fresh Snow over almost all the Open Trail Network.

Where there is Ice in the base, much of it is pre-existing, particularly and
typically around and below Contour Crests and Steeps as only one example...
But, as usual, what the Skier/Boarder feels will be directly proportional to
edge sharpness.
What you see above is the Surface of P’tit Bonheur. It is easy to make an edge
hold, if pressure and angle are not extreme. The Ski Pole Tips are easy to stick into
the surface, if it was ice, they would bounce off. The top layer is a blend of Machine
generated course to fine Granular, with Natural Snow, Some Sleety, Freezy-Rainy
Pellet-like particles and Traffic generated Edge-Ground dust. For the most part it
actually works quite well as a carving surface, but it does not yet have the depth to
perform very aggressive edge-set carving, so Smooth Application of Technique
get “Best Carving Results" and “Jamming" gets big skids.

One Mechanical Advantage Skiers have right now is that if you have
sharp edges and there’s “Icy” in the mix, you can Skate right over it
with good traction for the most part. This is especially useful on less
steep or Plateau sections.
The Evidence of Snow in the Trees from the Summit to the Versant Nord,
North side base throughout yesterdays Warm and enduring on through today
is adequate to demonstrate that the North side is an example of a Sector that
did not receive any significant rain while many regional areas immediately South,
got quite a bit.

We think after seeing what we see, that the restorative Warm/Arctic Froze to
Loose, Shred-able Winter Snow process will take close to a more average 3
days that would include today. That means a quite normal, incremental process,
as Crews work their way through the Grooming Schedule.


So far @22:30 Hrs, it’s Minus 25 C at South Base Resort Level...
so the Snow in the Trees is not going anywhere tonight.

Our One Pic. Sunny Forecast Day Scene for Today
(Should be very similar, from 2 days ago...):
As far as conditions go...

12 hours ago this was at the freezing mark... now it’s -19 C.

Plan Accordingly, but what we’re hoping to find today is some sort of repeat
of the Cryogenic phenomenon that caused the very beneficial and rapid recovery
that occurred a couple of days ago when we also had a quick drop in temps.
Grooming should have rendered out Very Smooth, but From “warm”
to “Cold” typically presents challenges, so Cautious Explorations
are Mandatory this morning!

Verify Safe passage BEFORE you go Ripping around.

There are always Sweet Spots in the Open Terrain, zones that either missed
the worst of what previous weather did, or zones that responded to Grooming
with good results, sometime both at once. The point is that there are so many
wild cards in the possible range of conditions out there today that only prudent
exploration will reveal those sweet spots, but they will be there.

Having recently gone through this process only a few days ago we are prompted to
say that while the normal Warm to Cold recovery process takes place on a gradual
scale over 3 days or so, recent experience shows that with the Give and Take of
Mother Natures Raw Weather gyrations that can almost immediately recuperate
some surfaces overnight, that process can actually be very much shortened to
sometimes large surface area recoveries in less than a day.

We can only hope until our Edges hit the Trails.

The benefit of all this recent Weather Drama is that even though we did
not get to utilize the Powder Snow in the way, or for as long as we would
have wanted Yesterday Morning, it represents a meaningful addition to the
base in both terms of the current building blocks of Open and Expanding
Terrain as well as the long term seasonal durability that assures Tremblant
trip planners they will have the best possible Mountain Utility throughout
the next 3 months of scheduled visits.

Being “North” has it’s advantages!

There are numerous Sweet Spots within Tremblant’s Open Terrain.

Prudent Exploration at conservative Speeds will get “Best Carving Results”.

Bring Back The Memories... Research Future Visits...
If you would like to look up dates you visited Tremblant, or you
want to research days/weeks/months to visit, you can sample what
they look like historically, month by month, year by year.

GoTo: Archive, Search Reports by Date: Index: http://tinyurl.com/yktelmu

When reviewing dates from any of the past, numbered, archived pages,
you can use the "Previous Topic" or "Next Topic" buttons, located
screen far right, in upper date/message bar to scroll through sequential
dates, or use your browsers "back" button to stay on the selected index
page for non-sequential date reviews in either forward or reverse order.

There are approximately 6, 25 day Index pages per season.

( If you "Bookmark" the link above, it will always take you to the
First index page with the latest posts. That gives you an immediate,
current to 25 day past, review scroll of Winter Alpine Conditions by
consecutive date.)
