A severe thunderstorm watch is in effect for northeastern Ontario as hundreds of residents remain without power amid an ongoing heat wave. Environment Canada issued the alert on Canada Day, warning of potential damaging winds, large hail, and heavy rainfall. The watch covers areas including Sudbury, North Bay, Timmins, and surrounding regions.
Power Outages Worsen Heat Concerns
Hydro One reported that approximately 1,200 customers were without power as of Tuesday afternoon, with outages concentrated in the Sudbury and Manitoulin Island areas. The utility said crews are working to restore electricity, but extreme heat and humidity are complicating repair efforts. “We are doing everything we can to get power back as quickly and safely as possible,” a Hydro One spokesperson said.
The outages come as temperatures in the region soared above 30°C, with humidex values reaching 40. Environment Canada has issued an extreme heat warning for much of northeastern Ontario, urging residents to stay hydrated and avoid strenuous outdoor activities.
Thunderstorm Risks and Warnings
The severe thunderstorm watch is in effect until Wednesday morning. Meteorologists warn that storms could produce wind gusts up to 90 km/h, hail up to 2 cm in diameter, and localized flooding. “Duration, not intensity, is the danger in Ontario’s latest heat wave,” said a meteorologist from Environment Canada. The agency advises residents to monitor alerts and take shelter if storms develop.
“These storms can develop rapidly and bring dangerous conditions,” the meteorologist added. “It’s important to have a plan in place.”
Heat Wave Continues
The heat wave is expected to persist through the week, with temperatures remaining in the low 30s. Overnight lows will offer little relief, staying above 20°C. Environment Canada recommends checking on vulnerable individuals, such as the elderly and those with chronic health conditions. Cooling centers have been opened in several communities, including Sudbury and North Bay.
“We’re all feeling the heat, but we need to look out for each other,” said a local health official. “Heat exhaustion and heat stroke are real risks.”
