FORECAST:

Dry cold air mass will bring clear skies today in a Northerly Flow Aloft. The upper ridge in the area should flatten on Friday with unsettled weather and moderating temperatures. A similar story for Saturday with more cloud cover and warmer temperatures as the next low moves down the coast in a Southwesterly flow aloft. Models are not in agreement for Sunday, may stay unsettled until Sunday evening when a weakening frontal band moves into the area. More on that as we get closer. Does look like a seasonal weather pattern on its way early next week with a freezing level fluctuating above the valley floor and possibly going as high as 2000 meters by Tuesday..Guesstimates: 1-3 cm by Sunday morning. 10-15 cm by Tuesday morning.




    Dry and slightly warmer today.

   Westerly flow aloft with unsettled conditions .





   Looking dry for Saturday with some unsettled conditions.

Not how I planned on starting the morning...stay safe out there kids!
Click here for Video of Choclate Bowl Ride: Nasty Ride

Today in Chocolate Bowl, size 2. Snowboarder from a different group was caught, pulled air bag and was only buried up to his waist luckily! South aspect, 1900m. Literally 10 minutes before this slide we dug a quick pit on the same aspect (South). 1 finger Windslab 35cms thick on top of fist minus. CTE 2 & CTE 1 down 35, on density change (faceting df's). Very touchy! Our group was sledding and playing on smaller low angle slopes.

Observed 3 other size 2 naturals on S aspects from the past 24hours of reverse loading. Play carefully out there guys!

    Always refer to a map or ask where the permanent closures are on the mountain!!!!

    Tube park just before dusk.

    Look out the window, that is where you will be riding tomorrow!!
