Toronto's severe thunderstorm watch has ended, but a heat warning remains in effect for the city and the Greater Toronto Area (GTA). Environment Canada issued the warning, urging residents to take precautions as temperatures are expected to remain high.
Heat Warning Details
The heat warning, which came into effect earlier this week, continues as of Tuesday evening. Daytime highs are forecast to reach into the low 30s Celsius, with humidex values making it feel even hotter. Overnight lows will offer little relief, staying in the low 20s.
Environment Canada advises individuals to stay hydrated, avoid strenuous outdoor activities during peak heat hours, and check on vulnerable family members and neighbors. Heat warnings are issued when temperatures are expected to pose an elevated risk of heat-related illnesses such as heat stroke or heat exhaustion.
Thunderstorm Watch Ended
The severe thunderstorm watch that was in place earlier has been lifted. However, isolated showers and thunderstorms remain possible in some areas. Residents should remain alert for changing weather conditions.
The combination of heat and humidity may still trigger pop-up storms, but they are not expected to be severe. Environment Canada will continue to monitor the situation and update warnings as necessary.
Safety Tips
- Drink plenty of water, even if you don't feel thirsty.
- Never leave people or pets inside a parked vehicle.
- Seek air-conditioned places, such as shopping malls or community centers.
- Wear lightweight, light-colored, and loose-fitting clothing.
