Conditions are favourable for the development of severe thunderstorms this afternoon and this evening over the foothills.

Another unstable day will promote the development of thunderstorms in parts of Alberta. Thunderstorms will likely develop this afternoon along the foothills and move eastward through the afternoon and evening hours. The main threats with these thunderstorms will be hail to the size of loonies, damaging wind gusts in excess of 90 km/h, and rainfall in excess of 50 mm.

East of the foothills, thunderstorms are now developing will be scattered over much of the province. These thunderstorms have the potential to become severe with accumulating small hail and heavy rainfall.

Thunderstorms will weaken this evening.

Fast-moving water across a road can sweep a vehicle away. Large hail can damage property and cause injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!

Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall.
