Heat Alert and Response System (HARS)

*See below for current heat advisories in place for the Interior Health region.

In collaboration with Health Canada and Environment and Climate Change Canada, Interior Health has developed the Heat Alert and Response System (HARS) to support communities to reduce the impact of extreme heat events.

Through a three-level heat advisory system, Interior Health keeps communities informed about the increasing risk caused by high temperatures over long periods.

Follow Interior Health on Facebook and Twitter to stay up-to-date with heat advisories in your community.


Heat Advisories 

The purpose of heat advisories is to notify communities of increased risk caused by exposure to heat, and precautions to take to keep yourself, and your loved ones, healthy during extreme heat events.

! No Current Heat Advisories

There are currently no heat advisories for the IH region. 

Heat Advisory Level 1 
  • Temperatures above 35°C for two consecutive days and overnight temperatures above 18°C.
  • Informs the public about the start of a heat event.  
Heat Advisory Level 2 
  • Temperatures above 35°C for three or more consecutive days and overnight temperatures above 18°C.
  • Informs the public of the extension of the heat event. The risk of heat-related illness overtime.
Heat Advisory Level 3 
  • Temperatures above 35°C for two or more consecutive days and overnight temperatures above 18°C, with a service disruption and/or alert of increased risk by the BC Centre for Disease Control.
  • Informs the public that there is a heat event in combination with a service disruption.



Service Disruption 

Service disruption is an extended power outage, extended poor air quality, extended water advisory, etc. During a service disruption, you and your family should be prepared to be self-sufficient for at least 72 hours.

To prepare for possible service disruption, you can develop a preparedness plan and make an emergency kit for you and your family.


As a step towards reconciliation, Interior Health acknowledges the land that we live, work, and play on as the traditional territories of the Dakelh Dene, Ktunaxa, Nlaka’pamux, Secwepemc, St’at’imc, Syilx and Tsilhqot’in peoples. It is with humility that we continue to strengthen our relationships with the First Nation, Métis, and Inuit peoples of the interior.
