We’re closely monitoring a slight risk for isolated severe thunderstorms this afternoon and evening in parts of central Alberta. Areas such as Edmonton, Edson, Red Deer, Whitecourt, Leduc, Camrose, Rocky Mountain House, Drayton Valley, High Prairie, Slave Lake, Lac la Biche, Westlock, Hinton, Olds and surrounding communities may see these storms. However, as they’ll be isolated, most areas will not receive any precipitation at all.

Damaging wind gusts of 80-100km/h, 3cm hail and isolated flooding up to 50mm are the main risks for these storms. Of course, frequent lightning and torrential rain are also expected for those who are affected by these storms.

The overall tornado risk is low so chances of a spin-up are unlikely. However, we all know that stranger things have happen so definitely make sure to have our free app Instant Weather to get notified of any and all alerts from Environment Canada for your area.

Environment Canada has also issued Severe Thunderstorm Watches for the region, shown below.

Environment Canada writes:

”Conditions are favourable for the development of severe thunderstorms this afternoon and evening that may be capable of producing strong wind gusts and large hail.

Damage to roofs, fences, branches or soft shelters is possible. When thunder roars, go indoors! Lightning kills and injures canadians every year.

Severe thunderstorm watches are issued when conditions are favourable for the development of thunderstorms capable of producing damaging hail, wind or rain.”


In addition to the severe thunderstorm risk, the Fire Danger map for Alberta shown below is very concerning as almost all areas of Alberta are under “Extreme” fire danger.

With the expected lightning, warmer temperatures and drier conditions, it’s very possible we could see new wildfires ignited from these storms today. Please stay safe folks and we’ll post more updates when available.
