Preparing for and staying safe during heavy rainfall
How to prepare for heavy rainfall
- Ensure storm drains near your house are clear and free of debris.
- Clear eave troughs and ensure they are pointed down and away from your home and foundation.
- Make sure that you and your family are as prepared as possible in the event a flood occurs.
Staying safe during heavy rainfall
- Wear protective clothing and seek indoor shelter.
- Stay away from windows and doors during heavy rain and strong winds.
- Avoid roadway underpasses, drainage ditches, low lying areas and areas where water collects – they can unexpectedly flood or overflow.
- Avoid driving in heavy rain due to poor visibility. If possible, park and wait until the rain has slowed or stopped to continue your journey.
- Do not try to drive across a flooded road. Water may be deeper and stronger than it appears and may contain debris, sharp or dangerous objects, pot holes or electrical wires.
- Vehicles can become unstable or even swept away if caught up in fast flowing or pooling flood waters. It only takes a few inches of water to displace a vehicle.
- Stay away from power lines or electrical wires.
- Monitor alerts and weather reports for flash flood warnings and updates.
Calgary gets to two types of summer heavy rains
- Large scale weather systems with long-term rainfall
These large weather systems can last several days and result in significant flooding. Environment Canada issues Rainfall Warnings for this type of event.
- Short-lived thunderstorms with significant rainfall
Within a short period of time, sometimes only minutes, localized downpours from thunderstorms can produce flash flooding. Environment Canada issues Severe Thunderstorm Warnings for these types of rainfall events.
