Weather forecast for the week – Warm-up brings increased risk of avalanches

Risk or Freezing rain in the mornings – Take care on the roads.

As temperatures in B.C.’s Interior rise, so does the risk of avalanches

Mild and above average temperatures are expected in the southern Interior this week and normal patterns will continue until Feb. 24 according to Environment Canada.  

Environment Canada says a strong Pacific frontal system is approaching the B.C. coast Tuesday, reaching the Interior on Wednesday. That system is tapping into a stream of sub-tropical moisture and warm air.

Tonight Mainly cloudy. 40 percent chance of flurries or rain showers overnight. Low minus 2.
Wed, 15 Feb Periods of snow or rain changing to rain showers in the morning. Risk of freezing rain in the morning. Snow level rising to 1000 metres late in the afternoon. Local snowfall amount 2 cm. Rainfall amount 5 to 10 mm. High plus 4.
Night Rain. Snow level 1000 metres. Amount 10 to 15 mm. Low plus 2.
Thu, 16 Feb Showers. High 7.
Night Periods of rain. Low plus 1.

“Whenever we see rain in the forecast, we get a little bit concerned for avalanche conditions,” said James Floyer, forecasting program supervisor for Avalanche Canada.

Ten to 20 millimetres of rain is expected to fall between now and Thursday on the western side of the Kootenays and Columbias.

Floyer says, right now, avalanche hazards are ‘considerable.’


Warmth is in the forecast and with it, the eventual arrival of the “pineapple-ish” express. Not as wet or long lasting as a more typical pineapple express, but with hints of sub-tropical origins. Lower mainland ski resorts will not like the next few days. Farther inland, the new snow we’ll receive may be a bit more “concrete-esque” than fluffy.

The wind and rain/snow from the north coast will continue to slide southwards while penetrating into the BC interior today and tomorrow. Cold air will be trapped in some interior valleys, giving an inversion with higher temperatures in the mountains, but as the warming is very strong, this will eventually arrive at valley bottom, and a normal vertical temperature gradient (temperature decreasing with height) will be re-established.

From today through Thursday, freezing levels will be rising dramatically (to nearly 3000m) through the south of the province and the northeast. In the northwest near Terrace, levels will rise to about 2500m. Toward the weekend these levels fall again.

The brunt of precipitation will be loaded onto coastal areas, with periods of snowfall arriving in central and southern BC interior.
