Extreme Cold


What is Extreme Cold?

The World Meteorological Organization defines Severe Weather as any dangerous meteorological phenomena with the potential to cause damage, serious social disruption, or loss of human life. Such weather events are not easy to predict as they may be localized and occur with little warning. For the purpose of emergency response, severe cold weather events in Vancouver are defined as:

  • Snowfall
  • Extreme Cold
  • Winter storms, freezing rain, or blizzards

Special Weather Statements and Warnings issued by Environment Canada (EC) are useful prompts for local risk assessments. However, these alerts are regional and do not always provide sufficient details regarding the Vancouver microclimate. For instance, snowfall levels are often higher in parts of the Fraser Valley than in the Lower Mainland. Click here to read more about regional differences.
