During high winds

Prepare you family or business for an emergency

Calgary is prone to strong windstorms and Chinook winds which can be dangerous. Flying debris and downed trees and power lines can lead to power outages, property damage, air and transit disruptions and serious injury. Windstorms in Calgary can happen anytime; good indicators of high winds include thunderstorms, intense low pressure centres, cold fronts, and Chinook arches.

How to prepare your property for high winds or a windstorm

  • Secure all loose items on your property and balcony (such as outdoor furniture or garbage cans) that might be blown around to prevent flying objects from injuring people and damaging property.
  • Trim dead branches and cut down dead trees to reduce the danger of these falling onto your property during a storm.
  • Clean gutters, drains and downpipes at your property and make sure your roof is in good repair.
  • Put your car in the garage, shelter pets and livestock and continue to monitor weather conditions.

How to stay safe in a windstorm

  • ​If you are outdoors, seek shelter inside a safe, enclosed building. Walking and balancing against winds of 70 km/h or more can be a risk to personal safety.
  • If you are indoors during a storm, shelter-in-place. Find a space away from windows or glass doors and stay clear of fireplaces.
  • If the wind causes a power outage, turn off all appliances and do not use generators indoors. Learn more about what to do during a power outages.
  • Stay away from downed power lines and cables. Learn more about what to do if you see a downed power line.
  • Avoid driving during periods of high winds. If you are in a vehicle during a windstorm, park away from trees or power lines and avoid the base of steep or unstable slopes and low areas prone to flooding. Stay inside the car.
