Heat Warnings and Extended Heat Warnings

Stay Cool Windsor-Essex logo

Beginning May 15, 2016, Windsor-Essex County Health Unit will implement a new Harmonized Heat Warning and Information System for dealing with heat events in Windsor and Essex County.

This new system provides a consistent approach for processing and issuing heat warnings in Ontario. It also provides evidence-based heat warning triggers which are based on the association between temperature, humidex and mortality. During this time, the website is updated daily with the current warning status.

The Windsor-Essex County Health Unit issues heat warning to inform residents of heat events with the Stay Cool Windsor-Essex program. When heat warnings are issued, you should take extra precautions to protect yourself and loved ones from heat related health risks.

Heat Emergencies are declared during extenuating circumstances (i.e., large scale power outage or drinking water emergency) during a heat event.

Heat Illness

For most people, heat-related illnesses happen when temperatures are high for a number of days (particularly if the night time temperatures do not drop), or if the humidity is high. While the health risks related to heat are higher for certain groups (such as seniors, young children, people taking certain medications and people with chronic conditions), everyone is potentially at risk. Fortunately, most heat-related illnesses can be prevented or treated if you are aware of the risks, signs and symptoms. This information can help you to plan ahead, and take action to protect yourself and your family.
