Hail

Definition

Calgary is vulnerable to hail. Environment and Climate Change Canada (ECCC) defines hail as precipitation in the form of solid ice pellets ranging from small pea-sized to large grapefruit-sized lumps that form inside strong thunderstorm updrafts. Hail can cause severe damage to properties and vehicles.

How to prepare

  • Routinely monitor local weather forecasts and Alberta Emergency Alerts for watches and warnings for thunderstorms (which often include hail).
  • Put together an emergency kit with essential supplies such as non-perishable food, water, flashlights, and batteries to get you through the first few days of an emergency.
  • Make an emergency action plan for your household so you know what to do and who to contact in an emergency.
  • Review your home insurance policy and ask your insurance provider what your policy covers in the event of damage from natural disasters.
  • Secure outdoor items by moving vehicles, patio furniture, and other belongings into a garage or shed, if possible.
  • Inspect and maintain your property, especially your outdoor area and roof to ensure protection against strong winds, rain and hail.
  • Keep trees and shrubbery trimmed and maintained to limit impacts from hail and winds.

What to do during

  • When hail or thunderstorms threaten, seek shelter immediately in a secure building. Bring your pets inside too.
  • Close all windows and doors. Stay away from windows, glass doors, and skylights.
  • Draw curtains and blinds to help contain broken glass if a window shatters.
  • If you’re driving, pull over safely and remain in your vehicle.
  • If you’re caught outside with no shelter, crouch down, face away from the wind and protect your head and neck with your arms.
  • Watch for flooded areas. Excessive hail combined with heavy rain can block storm drains and create local flooding.
  • Stay away from trees, towers, metal fences or poles to avoid lightning strikes.
  • Place any cars, RVs, boats, recreational vehicles, patio furniture and other large objects in a covered area, like a shed or garage if possible.

Know what to do after

  • Clean up and prepare to repair any damage.
  • If you are cleaning up after a hail storm, protect yourself by wearing personal protective equipment if required.
  • Check on your neighbours friends and family.
