Flash Flood Preparedness: What to Do Before, During, and After

If you’re concerned about flooding in your area, this guide can help you to be prepared in the event of an emergency.

Before a Flash Flood

• Sign up for local weather alerts (e.g., Environment Canada, Alert Ready).

• Know your flood risk. Are you in a floodplain? Near a creek or low-lying area?

• Keep your emergency kit stocked and accessible.

• Prepare a “go bag” with essentials in case you need to evacuate quickly.

• Make a family communication plan and meeting spot.

During a Flash Flood

• If there’s a warning: move to higher ground immediately.

• Never walk or drive through floodwaters.

• Stay off bridges over fast-moving water.

• If inside, go to the highest safe level (but not the attic unless there’s a way out).

After a Flash Flood

• Avoid flooded areas and listen to authorities for updates.

• Do not return home until it’s safe.

• Watch out for debris, downed power lines, and contaminated water.

• Take photos of damage for insurance and clean up with gloves and protective gear.
