Heat Warning in effect for:

  • City of Toronto

A hot airmass will continue to dominate Southern Ontario through Wednesday. Daytime highs in the low thirties are expected with warm overnight minimum temperatures near 20 degrees for the regions with heat warnings. For the regions without heat warnings in southern Ontario, their daytime highs are also expected to be in the low thirties, but their overnight low temperatures are forecast to stay a couple degrees shy of the heat warning threshold.

The hot weather conditions will likely ease slightly on Thursday, with high temperatures a couple of degrees cooler.

Watch for symptoms of heat illness, which include
- dizziness or fainting, nausea or vomiting
- headache
- rapid breathing and heartbeat
- extreme thirst and
- decreased urination with unusually dark yellow urine.
If you experience any of these symptoms during extreme heat, immediately move to a cool place and drink liquids. Water is best.

Frequently visit neighbours, friends and older family members, especially those who are chronically ill, to make sure that they are cool and hydrated.

Never leave people or pets in your care inside a parked vehicle or in direct sunlight.

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 storm.ontario@ec.gc.ca or tweet reports to #ONStorm.
