Know the risks of severe weather

Weather-related hazards in B.C. include:

  • Extreme cold: Exposure to cold temperatures can lead to frostbite or hypothermia
  • Snow and ice: Heavy snowfall, blizzards, icy conditions, and freezing rain can cause transportation challenges, increase the risk of slips and falls, and cause power outages
  • High winds: Can knock down trees and power lines and cause power outages, coastal flooding and damage to property
  • Thunderstorms and lightning: Can pose a risk to people and property, and in some cases cause power outages and wildfires
  • Heavy rain: Can lead to floods, landslides and erosion, especially in mountainous and coastal areas
  • Hailstorms: Can damage vehicles, buildings, and crops, and injure people and animals
  • Tornadoes: Are rare in B.C. but capable of causing severe damage with little warning

Climate change connection

Climate change is increasing the frequency and severity of weather-related emergencies.

Temperatures have been getting warmer in B.C. and are projected to continue rising. This is resulting in less rain in the summer, more intense and frequent rainfall in spring and autumn, and more severe storms in winter.

Severe weather preparedness and safety tips

Sometimes weather can be unpredictable and pose risks, but you can find peace of mind and stay safe by following these tips.

 

General preparedness

 

Extreme cold, snow and ice

Wear appropriate clothing

When you’re outside during cold conditions, stay warm and protected with seasonally appropriate clothing and gear, such as:

  • A hat and gloves to prevent heat loss
  • Waterproof or winterproof boots with good grip to stay warm and prevent falls
  • Bright colours and reflective clothing so vehicles can see you
  • Clothes in layers, with a wind resistant outer layer

Identify a winter weather buddy

If you live alone or experience mobility challenges during cold weather or snowy and icy conditions, make connections to find a winter weather buddy. Your buddy should be someone who can:

  • help with shoveling snow
  • help with running errands if you can’t leave your home
  • check in during cold weather or snowy and icy conditions

Winterize your home

A few simple steps can help prepare your home for winter conditions including extreme cold emergencies.

Winterize your vehicle

Ensure vehicles are ready for snowy and icy conditions with proper maintenance.

  • Install winter tires between October 1 and April 30. They provide better traction in cold temperatures and in snow, slush, and icy conditions
  • Keep your gas tank at least half full or electric vehicle half charged at all times
  • Visit Shift Into Winter for important road and vehicle safety information
  • Create a vehicle emergency kit with the following winter-specific items:
    • Windshield scraper
    • Shovel
    • Tow rope
    • Seasonal clothing
    • Booster cables
    • Reflective triangle or clothing
    • Antifreeze and windshield washer fluid
    • Sand or non-clumping kitty litter for better tire traction in snow and ice

Seek emergency warming centres if needed

In response to severe weather events and extreme cold:

  • Emergency warming centres and general warming spaces may be opened for the public. These are activated at the discretion of First Nations and local governments.
  • Locations may be listed on EmergencyMapBC.ca at the discretion of First Nations and local governments.
  • If a location is not listed on the map in your area, contact your Band office or local government.

For people experiencing homelessness:

  • Temporary winter shelters and extreme weather response shelter spaces are available. These shelters are funded by BC Housing and operated by community partners

Extreme cold health effects

Learn about the health effects of extreme cold and how to support those who are at higher risk:

 

High winds

High winds can knock down trees and power lines and cause power outages, coastal flooding and damage to property.

A few simple steps can help protect your home and property from damage by high winds:

  • Keep trees and shrubs trimmed to make them wind resistant. Remove damaged branches
  • Inspect your home for anything that may come loose during high winds, such as your chimney or roof shingles
  • Secure outdoor items, like lawn furniture and barbecues
  • Use surge protectors to protect appliances and electronics in the event of a power outage
  • Check for pre-existing damage to the foundation

During high winds, if you are outdoors keep yourself safe by watching for and avoiding knocked down trees and power lines. Seek shelter indoors if possible.

 

Thunderstorms and lightning

Thunderstorms and lightning can pose a risk to people and property, and in some cases cause power outages and wildfires.

Stay safe during a thunderstorm by seeking shelter immediately:

  • Go indoors or into a vehicle
  • Stay away from windows, doors, and anything that conducts electricity (such as, metal pipes, appliances, water)

While indoors, avoid using wired electronics or phones, as they can be electrical hazards. Use battery-powered devices like flashlights instead.

Tip: before a thunderstorm occurs, use surge protectors to protect appliances and electronics in the event of a power outage caused by thunderstorms.

 

Heavy rain

Heavy rain can lead to floods, landslides and erosion that can all pose a risk to people and property.

Protect your home from flooding

Start with some basic steps to prevent flood damage:

  • Store valuables and important items on high shelves or in water-tight containers
  • Clean gutters and keep storm drains clear
  • Clear snow at least 1 to 1.5 metres from your foundation in the winter

Protect utilities and appliances:

  • Raise appliances, electrical panels, and sockets
  • Anchor oil tanks and fuel supplies
  • Install a sump pump and backflow valves
  • Use waterproof materials (such as, tile floors, flood-resistant drywall)
  • Protect your gas and electrical systems and appliances with tips from Technical Safety BC

Seal and safeguard your home:

  • Apply sealant around basement windows and doors
  • Install self-closing flood barriers
  • Use flood-resistant exterior doors
  • Improve landscaping and drainage:
  • Enhance landscaping to direct water away from foundation
  • Use permeable paving for driveways and sidewalks
  • Dig trenches (call 1-800-474-6886 before you dig to prevent damage to gas or electricity lines)

Protect your home from landslides

Avoid actions that would make slopes unstable. Do not:

  • Undercut a steep bank
  • Build near the top or base of steep slopes
  • Place fill on steep slopes
  • Drain pools or otherwise increase water flow down steep slopes

Learn about whether your area may be at risk of a landslide. Look out for:

  • Evidence of old landslides
  • Steep slopes
  • Drainage channels on steep slopes
  • Coastal cliffs

Know who to notify if you recognize these signs. Find a local municipal contact or ask an expert to conduct an inspection, such as a geotechnical engineer.

Regularly inspect your residence, especially after heavy rainfall, rapid snowmelt, long dry spells, and earthquakes.

Know what to expect in an evacuation

If the danger from a flood or landslide is severe enough, you may need to evacuate. Learn what happens during an emergency evacuation, such as the different orders, where to get your information and more. 

 

Hailstorms

Hailstorms can damage vehicles, buildings, and crops, and injure people and animals.

Protect your home and property

There are steps you can take in advance to protect your home and property from hailstorms.

  • Park your vehicle in a covered area, or cover your vehicle's windows with blankets or other padding
  • Clear your eavestroughs of debris to ensure proper drainage
  • Cover outdoor items like barbecues and patio furniture
  • Do not store propane tanks indoors
  • Use window safety films to help prevent glass from shattering
  • Consider installing impact-resistant storm shutters for windows, skylights and doors
  • Consider installing impact-resistant roofing on buildings located in areas with moderate to high risk of hailstorms. Talk to a roofing specialist to determine the best hail-resistant materials and methods
  • Consider installing impact-resilient siding (e.g. not vinyl)

Stay safe during a hailstorm

During a hailstorm, seek shelter in a secure building. Stay away from windows, doors, and skylights

If driving:

  • Pull over safely
  • Turn away from windows to protect yourself from shattered glass

If caught outside with no shelter:

  • Crouch down facing away from the wind
  • Shield your head and neck with your hands
 

Tornados

Although rare in B.C., tornados are possible. It is important to know how to stay safe when one occurs.

If indoors:

  • Seek shelter in a well-supported basement or the lowest, most central room of a building.
  • Protect your head and neck
  • Stay away from windows
  • Avoid using elevators

If outside with no shelter:

  • Lie flat in a ditch or low-lying area.
  • Cover your head with your hand
  • Do not shelter under bridges or overpasses

Mobile homes:

  • Move to a sturdy building immediately. Mobile homes offer little protection during a tornado

If driving:

  • Do not try to outrun the tornado
  • Find shelter in a solid structure

If no shelter is available:

  • Park safely.
  • Seek low ground away from your vehicle
  • Watch for rising water and downed power lines

After the tornado passes:

  • Remain sheltered for at least 60 seconds
  • Stay alert for additional storms
