Heat Warning

Issued at 16:19 Monday 31 August 2015

A period of daytime temperatures of 29 degrees Celsius or more and overnight lows near 16 degrees will continue until early Wednesday morning. Humidex values will be in the mid to high thirties today and Tuesday. Slightly cooler temperatures are expected Wednesday afternoon. While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for - older adults - infants and young children - people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses - people who work in the heat - people who exercise in the heat - people without access to air conditioning and - homeless people. Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration. Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion. Environment Canada meteorologists will update alerts as required. Please monitor local media or Weatheradio. To report severe weather, send an email to or tweet reports to #ONStorm.
