Autumn began just a few days ago but it already looks and feels like winter in parts of British Columbia, Alberta and Saskatchewan.

A strong low pressure system prompted snowfall and winter storm warnings as up to 100 cm of snow fell across southern Alberta.

Gusty winds behind the system created blowing and drifting snow making highway travel treacherous.

Many early season snowfall records have been broken.

Snowfall amounts (in cm) as of 1pm MDT, 30 September:

  • Calgary 32
  • Claresholm  40-45
  • Lethbridge  50-60
  • Taber  60
  • Cardston area  70-90
  • Waterton Park  95

State of emergency lifted in Alberta

Days of severe weather including heavy rain, thunderstorms, hail, tornadoes and flooding led officials in western Alberta to declare a state of emergency.

However, Yellowhead County (west of Edmonton) dropped the declaration on Wednesday when floodwaters receded.

Many roads had to be closed or were made impassable after flooding and drivers were being asked to obey any barriers in place.

Residents were being warned about possible contamination of their drinking water.

Yellowhead County officials say at least 25 homes were directly impacted by floodwaters.

Thundersnow in B.C.!

A thunderstorm with snow is called thundersnow and it struck the British Columbia Interior just two days before the start of summer!

An unstable air mass bringing cold air from Alaska is to blame for the rare thundersnow which covered mountainous terrain in the Okanagan Valley with about 10 cm.

Snow fell above 1500 metres with a snow/rain mix down to 1100 metres and a chilly rain at sea level.

About 10 cm of snow was also expected in the Alberta Rockies from a similar system.

Spring blizzard sweeps Prairies

A strong low pressure system brought snow and strong winds to Alberta creating poor visibility and even thunderstorms and a possible tornado were reported.

Emergency officials scrambled to respond to more than 120 road crashes in Calgary on Sunday due to slippery, treacherous conditions after about 15 cm snow fell.

The spring blizzard continued to move across the Prairies where it dumped up to 45 cm on southwestern Saskatchewan including the Cypress Hills area.

The storm crossed into Manitoba with as little as 5 cm in the southeast to about 30 cm in the southwest.

Spring arrives early in the North

A warm air mass has surged into Western Canada this week bringing record temperatures to the region and also to the North.

Many communities from Yukon to Nunavut were well above freezing and into the double digits breaking March records.

Yohin Lake hit a record high of 18.8°C Monday and spiked to 20.2°C Tuesday marking the first time in March the thermometer has climbed above 20°C in Northwest Territories.

Daytime highs in British Columbia’s Fraser Valley hit the mid 20’s while Alberta residents enjoyed maximums in the high teens.

Unbelievable cold in the West!

An Arctic air mass has plunged much of Western Canada into the deep freeze with the coldest weather in nearly a decade.

Frigid temperatures have broken records in Saskatchewan, Alberta and British Columbia with the wind chill making it feel more like -50 in some areas!

Emergency responders had many calls related to frostbite and hypothermia with seniors and young children being especially vulnerable to the cold.

Auto clubs had almost ten times as many requests from drivers for dead car batteries.

Late summer and early autumn have been cold in southern Alberta but a big snowfall suddenly made it seem like winter.

Heavy snow moved across the Rockies and the foothills today dumping between 20 and 40 cm of snow (including over 30 cm at Calgary International Airport).

Environment Canada warns the snow will continue into Wednesday morning with a few more centimetres expected.

Traffic also ground to a halt as vehicles became stranded on snowy and icy highways.

September snow in Alberta!

Cold Arctic air has combined with moisture moving over the Rockies to give Alberta a taste of winter in late summer.

Forecasters say northern Alberta including Edmonton could receive at least 8 cm snow with up to 15 cm in Jasper.

Temperatures are hovering near or slightly below freezing with a plunge to -6°C in northern British Columbia.

Environment Canada says more seasonable weather is not expected to return until early next week.

Smoke impacts Alberta air quality

Smoke from forest fires in British Columbia is streaming into Alberta resulting in poor air quality and reduced visibility.

Environment Canada says smoke conditions can change quickly during wildfires but air quality will be poor for the rest of the week.

Small children, seniors and anyone with chronic conditions are especially at risk.

British Columbia has declared a state of emergency with over 560 out-of-control wildfires forcing 3,000 residents from their homes and another 20,000 are under evacuation alert.
