It’s been a busy week of severe weather threats in Alberta, and that risk continues today with thunderstorms that may produce very large hail and a tornado potential. According to Environment and Climate Change Canada (ECCC), thunderstorm outlooks from the Storm Prediction Centre show many major cities in Alberta at risk of severe thunderstorm activity today, July 17. There is a moderate-risk zone present in the province today, with heavily populated areas such as Edmonton, Sherwood Park, Spruce Grove, Leduc, Edson, Calgary, Okotoks, Airdrie, Red Deer, Cochrane, and Lethbridge grouped into that risk area. Weather risks in that area include wind gusts of up to 110 kilometres an hour, with thunderstorms that could produce hail up to five centimetres in size, the equivalent of a golf ball. Up to 50 millimetres of rain may also occur if a thunderstorm materializes, and the possibility of a tornado forming can’t be ruled out.
