Expect hot, humid and sticky weather this weekend that feels like 40C or more.
Environment Canada has issued a heat warning for Toronto and surrounding regions, calling for highs in the 30s and overnight lows in the 20s on Saturday and Sunday. A mixture of sun and clouds is expected both days with the possibility of showers.
That means some relief from the sweltering heat until cooler temperatures arrive on Monday.
Heat warnings are issued when very high temperatures or humidity levels are expected to pose a risk of illness, such as heat stroke or heat exhaustion.
Young children, pregnant women, older adults, those with chronic illnesses or people who work outdoors face the greatest risk, the federal weather agency says.
Stay cool with the following tips, it says:
- Drink plenty of water even before you feel thirsty.
- Check on elderly family members, friends and neighbors.
- Never leave people or pets in parked vehicles.
- Take breaks in cool places if you work outdoors.
