Ottawa is set to experience another round of intense heat and the possibility of thunderstorms this weekend, according to Environment Canada. After a hot and cloudy spring day on June 12, temperatures are expected to remain elevated, with humidity making conditions feel even warmer.
Weather Outlook
The forecast indicates a mix of sun and cloud with a high near 30°C, but the humidex could push the perceived temperature into the mid-30s. Thunderstorms are likely to develop in the afternoon and evening, bringing the risk of heavy rain, strong winds, and lightning. Residents are urged to take precautions, especially those with outdoor plans.
Safety Tips
Health officials recommend staying indoors during peak heat hours, drinking plenty of water, and checking on vulnerable individuals. If thunderstorms occur, seek shelter immediately and avoid open fields, tall trees, and water bodies. The city has opened cooling centers for those without air conditioning.
This weather pattern follows a series of storms that have affected other parts of Canada and the United States. In recent days, severe hail damaged vehicles in Regina, and tornadoes in the central U.S. caused fatalities. While Ottawa is not expected to face such extreme conditions, the threat of localized flooding and power outages remains.
For the latest updates, follow local weather alerts and avoid unnecessary travel during storms. The heat is expected to persist into early next week before a cold front brings relief.
