Overview
A tornado is a violent rotating column of air extending between a thundercloud and the ground and can reach speeds of up to 400 km/h in some cases. Most develop in the late afternoon and early evening.
In most of Alberta, a wind warning is given for winds expected to reach at least 70 km/h, or gust at least 90 km/h.

Tornado and extreme wind facts
When you are aware of a tornado or extreme winds in your area, remember the following:
- May through September is tornado and hail season, with mid-June to early August being the peak time.
- Tornadoes are often hard to see from far away and not all have a visible funnel cloud.
- Tornadoes usually come from the south or west, but can quickly change direction without warning.
- Large hailstones often accompany tornadoes. Take cover when hail begins – do not go outside.
- A tornado is deceptive – it may appear to be standing still when it is moving toward you.
Seek shelter and stay safe
When you are aware of a tornado in your area, it is important to seek shelter immediately and remain in place until the severe weather passes. If you are outdoors and exposed, get to low-lying ground, lay flat and protect your head from flying debris.
Stay safe by being informed of severe weather in your area by following local forecasters on social media, listening to the radio, and downloading alert apps onto your phone, such as Alberta Emergency Alert. Have an emergency plan so you are prepared to leave early and know in advance where to safely take shelter from the threat.
Always remember to follow instructions from authorities. Disobeying an order puts lives at risk.
