A weather system is moving through Mississauga, and is expected to bring periods of rain and a risk of a thunderstorm.  

Reminders

Periods of heavier rain may lead to higher flows and water levels throughout the city’s watershed. For safety, residents are urged to:

  • Stay away from rivers, creeks, stormwater ponds and Lake Ontario.
  • Avoid low-lying areas that may flood quickly.
  • Watch for washouts near culverts and bridges.

Driving and outdoor safety

Wet weather can create hazardous driving conditions. Residents are reminded to:

  • Allow extra time for travel, slow down and leave extra space between vehicles.
  • Drive according to road and weather conditions.
  • Avoid driving through flooded roadways or pooled water.
  • Turn around and find another route if lanes are impassable.

Pedestrians and cyclists should also take extra care, as wet surfaces can be slippery and visibility may be reduced.

What is a flood watch or warning?

  • Flood outlook: Early notice of the potential for flooding.
  • Flood watch: Flooding may happen in certain areas.
  • Flood warning: Flooding is happening or will happen soon.

If a flood warning has been issued, act immediately to protect yourself from danger and your home from flood damage.

How residents can prepare

Small steps can make a big difference in reducing flooding risks:

  • Clear leaves and debris from storm drains near your home.
  • Check downspouts and ensure water drains away from foundations.
  • Secure loose outdoor items that could be affected by wind.
  • Ensure you have your emergency kit ready in case of power outage during heavy rains.
