Storms & floods
Severe weather can develop without warning, affect your power supply, and create dangerous situations.
The information in this handbook is offered as a tool to help you plan your personal emergency response.
If you see a tree touching a power line, call 911 or your local emergency services immediately.
High wind conditions can push over hydro poles and cause trees to contact power lines. Stay at least 10 metres away from power lines, trees, or anything they may be touching – including puddles. Any tree branches touching a power line may still be energized.
A winter storm can strike quickly, so plan ahead.
During a power outage, stay calm. Your house will remain warm for several hours. If you have an alternate heat source, use it before the house cools, and maintain adequate ventilation. Consider if a backup electric generator would be a good choice for your home or business.
When heavy snowstorms sweep through an area, ice can build up on power lines and cause flickering or power outages.
Stay clear of low or sagging power lines. Travelling under these lines can be dangerous. Downed power lines may be energized so stay at least 10 metres away from the power lines or anything they may be touching.
Spring run-off flooding may develop slowly but heavy rain can cause flash floods in lowland areas and basements. We disconnect electrical service in flooded areas.
If an electrical or natural gas emergency occurs, flood-related or otherwise, call 911 or your local emergency services immediately.
Before a flood:
- if your basement is dry, turn off the main power switch;
- make sure your sewer backwater valve and sump pump work to prevent a backup;
- move electrical equipment such as TVs, stereo, and computers, out of your basement to an upper floor;
- check with us if your natural gas service should be shut off.
During a flood:
- avoid standing water as underground or downed power lines can carry an electric charge;
- watch for submerged poles and low-hanging power lines if travelling by boat;
- be aware that water currents can change quickly as floodwater levels rise and fall;
- do not travel after dark unless it is an emergency as power lines are almost impossible to see.
After a flood:
- do not enter any buildings that may not have had the power disconnected, and are still under water or were flooded;
- call us any time at 204-480-5900 (Winnipeg) or 1-888-624-9376 (toll-free) to disconnect the power.
Even if your building did not suffer water damage, the interior structure may be wet. Electricity can move through water or wet flooring and cause severe injuries or death. Even a small amount of water can be dangerous.
A licensed electrician should replace and test all wiring, outlets, baseboard heaters, and other electrical hardware that was in contact with floodwater before your power is restored.
A licensed heating contractor should inspect any natural gas appliances that were in contact with floodwater to see if they must be replaced.
