Ottawa Braces for Scorching Heatwave: Environment Canada Issues Multi-Day Warning
Ottawa Citizen

Ottawa and the surrounding National Capital Region are facing a significant heatwave, as Environment Canada has issued a multi-day heat warning. The advisory, posted Saturday evening, cautions residents of both Ottawa and Gatineau to prepare for prolonged periods of high temperatures and humidity.

What to Expect: The warning indicates daytime highs will consistently soar above 30°C (86°F), with humidex values potentially reaching dangerous levels, making it feel significantly hotter. Nighttime temperatures are also expected to remain elevated, offering little respite from the heat. The warning is currently in effect for several days, with Environment Canada advising residents to monitor forecasts closely for updates.

Health Risks and Precautions: Prolonged exposure to such heat can pose serious health risks, particularly for vulnerable populations including young children, seniors, and individuals with pre-existing medical conditions. Environment Canada is urging residents to take the following precautions:

  • Stay Hydrated: Drink plenty of water throughout the day, even if you don't feel thirsty. Avoid sugary drinks and alcohol, which can dehydrate you.
  • Seek Shade and Cool Environments: Spend time in air-conditioned spaces whenever possible. If you don't have access to air conditioning, visit public cooling centres (check your local city website for locations). Seek shade during the hottest part of the day.
  • Avoid Strenuous Activities: Limit outdoor activities, especially during peak heat hours (typically between 11 AM and 4 PM).
  • Check on Others: Reach out to friends, family, and neighbours, particularly those who may be at higher risk from the heat.
  • Never Leave Children or Pets in Vehicles: Temperatures inside a vehicle can rise rapidly, even on a moderately warm day, posing a life-threatening risk.

Cooling Centres and Resources: The City of Ottawa and the City of Gatineau have announced the opening of several cooling centres to provide relief from the heat. Information on locations and hours of operation can be found on their respective websites. Links are provided below:

The heatwave is expected to continue for several days, so it's crucial to take precautions and stay safe. Remember to prioritize your health and well-being during this period of extreme heat.
