   As of 07:00 hrs this am we have some thin high scattered cloud and unlimited visibility.



FORECAST:

The upper ridge will bring mostly sunny skies and warm temperatures for the next few days in a Northeasterly-Easterly flow aloft. The FL will spike to around 3500 meters today and there is a chance of some cloud in the mix as well. Still some cloud coming down through the interior of the province, but may not reach us. Should see more cloud in the area by Sunday as the ridge begins to weaken and low level onshore flow will bring cooler temperatures. A low is forecasted to bring periods of light/moderate precipitation next week for Tuesday and Wednesday. More on that as we get closer. On this date in 2013 we had a high of  27.2 Deg C. Wonder if that # will be broken today or tomorrow?

From Northwestcentral B.C. Ski Touring Information:

Guido Schnelzer
Drove east towards Kitwanga yesterday and observed a recent or potentially fresh looking deeper slab avy across the Skeena on Mount Knauss. Light was a bit flat but couldn't see any obvious large trigger like cornice collapse or significant wet surface event with mass...appeared to be a natural failure. Steep east quadrant terrain, alpine start zone. Further obs revealed a plethora of wet surface activity but no other slabs. It will be interesting to see if this coming spate of no significant overnight refreeze temps will induce further deeper slab events.
