Weather AlertTORONTO – WEATHER – If you are heading to Toronto today, you won’t need a sweater. The city is under a heat advisory. Those conditions are expected to bring thunderstorms into the forecast later today for Toronto.

If you are flying to Toronto, weather conditions later on Friday could cause delays. Check Flight Tracking for the latest updates.

A hot and humid airmass is expected to affect portions of Southwestern Ontario, Central Ontario and the Golden Horseshoe today. High temperatures near 30 degrees and humidex values near 40 are forecast for this afternoon. A cold front will sweep across the area this evening bringing a return to near seasonal temperatures for the weekend.

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.

The area is also expecting Thunderstorms as a result of the weather.

Environment Canada has Thunderstorm watches and advisories in place for many parts of Southern Ontario:

Severe thunderstorm watch in effect for:

  • Bruce Peninsula – Sauble Beach – Tobermory
  • Hanover – Dundalk – Southern Grey County
  • Owen Sound – Blue Mountains – Northern Grey County
  • Saugeen Shores – Kincardine – Southern Bruce County

Conditions will be favourable for the development of severe thunderstorms through the afternoon and early evening hours. Damaging wind gusts, large hail and torrential rainfall are all threats. Isolated tornadoes are also a risk.

Be prepared for severe weather. Take cover immediately, if threatening weather approaches. In Canada, lightning kills up to 10 people every year. Remember, when thunder roars, go indoors.

Emergency Management Ontario recommends that you take cover immediately, if threatening weather approaches.
