Yesterday morning was very reactive, not much snow with little destructive potential but very touchy. It will be interesting to see what happens in the alpine today.

Strong winds in the alpine kept us out of that zone, even tree line lifts were feeling the brunt of the wind.

At 2284 meters the temperature was -11, winds were 15-20 KPH form the SW. At 1650 meters the temperature was -7, 5 cm of new snow fell over night with 23 in the past 24 hours. In the valley it was -1.  Observations taken at 06:00 hrs. Maximum gusts yesterday in the alpine were 95 KPH. It snowed 6 cm at 1550 meters, Catskinner weather plot last night.

For the forecast we can expect unsettled conditions for today, as the NW Flow aloft prevails, with some flurries during the day as a weak surface ridge develops.  The next wave arrives Sunday with an additional 12-16 cm by Monday morning. A warm front passes through tomorrow followed by a cold front tomorrow evening giving us a similar system to the one that hit us yesterday. The flow continues into next week with more snow expected. Unsettled weather with periods of light snow. It appears there may be some ridging on Monday, stay tuned!

More warnings from the media, it always amazes me that more avalanches happen when the rating is considerable, then when it is high. As per this article, people need to have experience when dealing with a considerable hazard and greater. The Vancouver Sun

Below is an image sent to me from some where on the Duffy from yesterday, a picture is worth a thousand words!

12 cm fell at 1550 meters by 12:00 yesterday at Catskinner weather plot. At 14:30 there was still 12 cm recorded there, while at 1650 meters on Whistler at the Pig Alley plot 18 cm was recorded at 14:30 hours. Considerable variability occurs in our region!! As mentioned  in other posts, these weather plots are only 4.5 kilometers apart.

During the day there were several holes over our area. Definitely unsettled conditions.

This is what our area looked like from space yesterday! There is certainly more precipitation on the way. You can see the majority of the precipitation went to our southern neighbours.
