Alert: “brief blizzard-like conditions” possible East Vancouver Island Overnight

Update: 7:45AM Saturday

Teresa Pavin, please contact me at alberniweather@gmail.com so we can arrange your snow prize! 🙂

The snow is done for Alberni (the cold is not!) but the snow is still falling in areas south of Nanaimo.

Snow bands now focused on previously forecast areas. Ladysmith, Duncan and the Gulf Islands.

Luckily it doesn’t look to be falling too hard.  The webcams in Chemainus and Duncan don’t show much or any snow on the roads.  It may be signficantly different in specific areas though so please drive carefully.

Roads looks wet.  Watch for ice where salt hasn't been spread.

Have a great Saturday!  And Teresa Pavin! Please contact me at alberniweather@gmail.com

Update: 10:10PM: Hump is open again but I still highly recommend NOT travelling until the snow stops Saturday morning.

We have around 2cm or 1″.  How much do you have?  The snow has stopped falling at Alberniweather for now.  The temperature is hovering around 0ºC and the wind continues from the East.

Update 9:20PM – Traffic on the Hump is being blocked and/or intermittent.   Just don’t drive tonight.  Just don’t.

Update 8:45PM – Unconfirmed reports – The Hump is closed.  Working to confirm.

Update 8:30PM –  Teresa Pavin is the winner of the snow contest!

The unexpected, and heavy snowfall continues.  Remember that even the best model said it wasn’t going to start until at least 10PM, and it was only supposed to happen on South Vancouver Island.  This is quite a dramatic departure from those forecasts.

And the crazy thing is, the current forecast that was just released in the past hour still has the snow only on the South Island.

The forecast model has still completely missed the more northerly snow band that is now affecting us in Port Alberni.
You can see the lines of "strait effect" snow coming down from the mainland inlet and lining up with us from Texada Island (anyone know what that Inlet is called? and one from Howe Sound to the south island

Update 7:15PM – WE HAVE A SNOW CONTEST WINNER!

Teresa Pavin! She guessed 1:30PM

And a very honourable mention to Astrid Braunschmidt who used her super meteorologist powers to predict exactly the right time, but she didn’t get her guess in before the closed! 😉

It is beautiful at Harbour Quay!

Update 4:35PM:

It has started quite early.

Light snow, likely not sticking, on the radar and being reported all over the South Island including Port Alberni.

Update: 3:25PM – Possible snow for Port Alberni – One model says so.

Scott Sistek of KOMO news in Seattle just tweeted this photo:

On the left, the model I use (UWash) doesn't show snow accumulation for Alberni - On the right though, the EURO model from Weather Bell (a pay service) shows 1" of snow by morning in the Alberni Valley.  So heads up.  The possibility is there.

Snow is still unlikely for the Port Alberni area.  However, on the East Coast, EC is now predicting possible snowfall “similar to lake effect” and “brief blizzard-like” conditions overnight at times.   That’s right folks, for a select few of you, it’s like our own mini-version of Buffalo snow.

Read it yourself!

First light snow over the South Coast…

A ridge of high pressure building over the BC Interior is forcing Arctic air south through the Fraser Canyon and west through the mainland inlets and valleys along the coast. The leading edge of the cold, dense outflowing air – the Arctic front – will cause wind speeds to increase as the air temperature decreases.

A small influx of moisture with the Arctic air will create light, fluffy, very low-density snow. As the ground freezes and the wind persists, the accumulating snow will reduce visibility in blowing snow.

The Arctic air will absorb moisture from the sea as it crosses the Strait of Georgia. When the modified Arctic air moves onshore along the East Coast of Vancouver Island, local snow streamers – similar to lake effect snow – may develop. Snowfall accumulations will vary significantly over small distances, ranging from a trace to 5 to 10 centimetres. Rapidly variable and brief blizzard-like conditions may develop in snow-belt and blizzard prone areas of the Lower Mainland such as Sumas Prairie, the Gulf Islands, and on the East Coast of Vancouver Island.

The public is advised to monitor future forecasts and warnings as warnings may be required or extended.

Thank goodness it is happening overnight and should be done by first light!

I will update more as we go tonight and tomorrow morning.  PLEASE DRIVE CAREFULLY TOMORROW.

  1. Ya, I hit “Brief Blizzard Like Conditions” on my ride home from work – freezing rain, or something crystal-like along River Road. I saw the falling barometer and wondered what was going to happen!
