The City of Kingston experiences a variety of weather conditions. For details on how to deal with extreme weather please review the information below.

Extreme Cold

Kingston winters often bring extreme cold, heavy snow, ice, sleet, and freezing rain. These elements can pose serious hazards. When a winter storm warning is in effect, monitor the radio, television and weather agencies for more information and instructions.

KFL&A Public Health has a cold weather response plan that uses Environment and Climate Change Canada (ECCC)'s information and thresholds to inform residents about the cold. The cold weather thresholds are under review and will be posted when they are updated.

Right now, Cold Weather Health Warnings are issued when the temperature is forecast to be -25°C or colder, when a wind chill of -28°C or colder is forecast, or when extreme weather conditions – blizzard or severe snow storm– are forecast for the KFL&A area by ECCC.

Severe Weather

During severe weather, such as thunderstorms, flash flooding and tornados, check the radio, television and Environment Canada  for more information. Environment Canada provides forecasts and warning information 24 hours a day.


  • Close all windows and doors.  Secure loose objects outside so they don't get blown around.
  • Disconnect electrical appliances, such as radios, TVs, computers, etc. as they can conduct electricity.
  • Get to the basement or main level of your house if it's a severe storm.
  • If caught outside, do not lie flat but squat low to the ground.
  • Take shelter in a building or depressed area such as a dry ditch or culvert.  Do not take cover under trees.
  • Avoid handling metal, electrical equipment and telephones.
  • Do not use water faucets or any water connected to a plumbing system.  Lightening can follow wires and pipes.
  • If swimming or in a boat, get back to shore immediately.
  • If you are in a car, stay there.

Flash Floods

  • Move pets, furniture, appliances and other belongings to higher ground.
  • Make sure basement windows are closed.
  • Seek higher ground if you see rapidly rising water.
  • Never drive your vehicle through standing water.  Do not cross flowing water.

Information on basement flooding can be found on our Utilities Disruptions page.


  • Go to the basement or take shelter in a small interior ground floor room, such as a bathroom or closet.  Protect yourself by taking shelter under a heavy table or desk.
  • Stay away from windows, outside walls and doors.
  • If outside, take cover in a ditch or recessed area.
