Tornadoes can bring massive winds, carve destructive paths, and can sometimes strike without time for a tornado warning. Learn the signs of a tornado and what to do before, during, and after a tornado event.
BEFORE A TORNADO
- Prepare your emergency kit
- Prepare your household emergency plan
- Know the potential warning signs of tornadoes (for more information, check the Potential Tornado Warning Signs section below)
- Seek shelter immediately if a tornado warning has been issued, or if you believe a tornado could occur
- Know the difference between a tornado watch and a tornado warning:
Tornado Watch: When conditions are favourable for the development of severe thunderstorms with one or more tornadoes
Tornado Warning: When a tornado has been reported; or when there is evidence based on radar or from a reliable spotter that a tornado is imminent
POTENTIAL TORNADO SIGNS
- Severe thunderstorms, with frequent thunder and lightning
- An extremely dark sky, sometimes highlighted by green or yellow clouds
- A rumbling or whistling sound
- A funnel cloud at the rear base of a thundercloud, often behind a curtain of heavy rain or hail
DURING A TORNADO
The safest thing to do during a tornado is to take cover in a well-supported basement area, stay close to the ground, and watch for flying debris, especially glass.
- If you are indoors, the safest place is the lowest and most central room. Get under a sturdy piece of furniture, use your arms to protect your head and neck, and don't open windows or use elevators
- If you are outdoors, go inside right away if possible, otherwise lie flat in a ditch or sunken ground and cover your head with your hands. DO NOT go under an overpass or bridge
- If you are in a mobile home, go to the nearest sturdy building or shelter immediately
- If you are in a vehicle or driving, drive to the nearest solid structure and take shelter. If no shelter is available, pull off the road, park the vehicle, turn on your hazard lights and seek shelter in a low lying area away from your vehicle
AFTER A TORNADO
Once a tornado has passed, the threat for additional tornadoes may remain. Stay alert and abide by weather alerts until until you are certain the threat has passed.
- Remain in a covered position for at least 60 seconds after the tornado has passed
- Follow instructions from local emergency officials
- If you have to evacuate your home, make sure to bring your emergency kit and other essential items
- Only make phone calls if someone's life is in danger - otherwise use texting or data-based messaging to communicate
- If you suspect your home is unsafe, DO NOT stay or re-enter
- Don't light matches or turn on electrical switches until you're certain there are no gas leaks or spilled flammable liquids.
