  660 meters   +1, Valley Temp, Max Temp Yesterday was +9.7,  0.0 mm of Precip recorded yest

    As of 07:00 Hrs this am we have overcast skies and unlimited visibility.

    Looking a lot like winter. Southerly flow this morning shifting later to Northerly.



For the forecast, a trough to our South is still pushing some cloud into our zone this morning but a high pressure aloft in a Northerly flow will bring cool sunny weather for later this morning, into Wednesday. We will likely see some cloud by Wednesday late in the day as the first frontal band moves onshore. A deep low out of the Gulf of Alaska will slowly move South sending a series of frontal bands our way into the weekend. We can expect a series of wet cool fronts with windy conditions Thursday into Sunday. The freezing level will drop Monday as a short lived arctic outbreak pushes just East of Whistler, than rise to around 2500 meters on Wednesday than drop back down to about 1800 meters Thursday through Saturday. Feels like an early winter is a good possibility.



Have lost two of my advertisers this fall so far, if anyone has any company contacts that may have an interest in placing an advertisement on the blog please e mail me at wwflann@me.com. If I cannot find enough support to generate some revenue, 5 years of hard work and archived information may come to an end. Any ideas would be appreciated!!

Thanks for all the support and ideas. Some feel I should have a subscription where users would pay by the month. Would like to keep the blog available to all users!!! 

    Lingering cloud this morning should dissipate.

    Looking like a nice day.

    Flow for this week, looks like more snow in the mountains by the end of the week!!

    Nice until Wednesday

    First frontal band on Thursday.

    Cool wet frontal bands over the weekend with strong winds.

    Northwesterly flow for the weekend.

First intel of the season from Jeff Van Driel:

30-45 cms on Horstman Glacier at 2100 M with a 1 cm breakable surface crust. Unconsolidated stellars below. Loose solar size 1 and a couple of slab avalanches up to size 2 in steep lee slopes around the Horstman glacier.

    Snow accumulation at 680 meters Saturday afternoon.

    Sunday morning--Pemberton Valley. 43.7 mm of rain recorded Friday-Saturday at the airport.

    Pretty impressive for October 9, 2016.
