2180 meters     -5, Winds were 10-15 KPH from the SSW
1860 meters     -6, Winds were 10-15 KPH from the E

  660 meters    +3, Valley Temp, Max Temp Yesterday was +9.5, 1.2 mm recorded on Sunday

    As of 07:00 Hrs at 1835m we have broken cloud and unlimited visibility, cloudy below 1600m.

Large avalanche cycle Saturday-Sunday in the Whistler area, numerous size 1-2.5 avalanches observed in HST some stepping down into March 11 crust/facet PWL. Some images and observations below.


For the forecast, a weak upper level and surface trough will bring unsettled weather to the area today in a Southwesterly flow aloft. The freezing level should rise to 1500 meters during the day dropping to 1100 meters this evening. There is the possibility of some isolated showers during the day. A very weak ridge will build for Tuesday but with the low pressure so close we will see unsettled conditions but drier that today in a Northwesterly flow aloft. A warm front moves into the area on Wednesday
with the FL rising from 1200 meters to 2000 meters by Wednesday night. The front will bring cloudy conditions with light precipitation and a rising Fl into Thursday morning. (2500 meters)  A weak high pressure builds into the area Thursday afternoon with unsettled conditions through to Friday evening. A warm frontal band is expected on Saturday with moderate precipitation. Guesstimates: trace to 2 cm above 1000 meters by Wednesday morning, 3-5 cm above 1800 meters by Thursday morning.

Intel from Doug Tuck up on the Duffy:
Size 3.5. With a better look it could be a 4. FL 400X.8m est. Suspect the March 11th FCxrCR layer. Likely occurred mid afternoon Saturday during a heavy convective shower judging from the lack of snow on the bed surface. Sorry about the poor photo quality. Cell phone through the binoculars.
Cheers
