Hot and humid weather until Thursday
Environment Canada is warning of hot and humid weather from Tuesday to Thursday.
Very warm air is projected to arrive on Monday over Southwestern Ontario. The heat is expected to intensify and spread over much of southern Ontario on Tuesday, building into a three-day heat episode.
Temperatures are expected to reach well into the thirties on Tuesday, with a humidex reading in the low 40s until Thursday.
Night-time temperatures will also remain very warm and are not expected to drop below 22 degrees in many areas.
This will make for very uncomfortable conditions and moderate to high readings in the air quality health index. It is advised to stay in an air conditioned place or seek shade when possible, drink plenty of water and limit physical outdoor activity.
As the hot air mass moves further east the statement will be extended and humidex advisories may be issued.
