Severe Storms – What to do? - Public Safety Canada
You can greatly lessen the impact of a severe storm by taking the time to prepare in advance. This involves three basic steps: find out about the risks and the type of storms in your region; make a family emergency plan, so that everyone knows what to do, and where to go in case of an emergency; get an emergency kit, so that you and your family can be self-sufficient for at least 72 hours during a severe storm.
