Severe Thunderstorm Watch

Issued at 12:05 Thursday 27 July 2017

Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing strong wind gusts, damaging hail and heavy rain.

An unstable airmass over Alberta will set the stage for thunderstorms this afternoon and this evening. Some of these thunderstorms will have the potential to become severe. Hail to the size of golf balls or perhaps even larger, as well as wind gusts in excess of 90 KM/H, are possible with these severe thunderstorms.

In addition, later this afternoon and this evening, it appears there exists some potential for a few tornadoes. As the day progresses and the scenario becomes more clear, parts of the thunderstorm watch may be upgraded to a tornado watch.


Very large hail can damage property, break windows, dent vehicles and cause serious injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Remember, severe thunderstorms can produce tornadoes.

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.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ABStorm.
