Southwestern Public Health issues extreme heat warnings when Environment Canada forecasts temperatures that are expected to be at least 31°C and overnight temperatures are at or above 20°C for two days or the Humidex is forecasted to be at least 40°C for two days.

Environment Canada is forecasting the first heat event of the season starting Monday afternoon and continuing into Tuesday. Daytime highs will be near 30 degrees Celsius, and humidex values near 36. Overnight low temperatures are expected to be near 20 degrees Celsius. This heat event is expected to end Tuesday night.

During an extreme heat warning, residents should take precautions to protect themselves and the most vulnerable from heat related illness. Those most vulnerable to the effects of the heat include older adults, infants and young children, outdoor workers, and people experiencing homelessness who do not have shelter, proper clothing or food. Anyone who experiences physical distress because of extreme temperatures should seek medical attention immediately, either by calling 911 or by going to the nearest emergency department.

What you should do:

• During extreme temperature conditions, stay indoors in an air-conditioned building if possible
• Limit time in the sun when the UV Index is most intense, between 11am - 4pm
• Seek shade when outdoors, especially during mid day
• Drink plenty of water to stay hydrated and decrease intake of caffeinated/alcoholic beverages
• Take cool showers or baths
• Apply Sunscreen with SPF 30 (or higher), 20-30 minutes before going outside to ensure absorption and re-apply every 2-3 hours
• Check regularly on children, elderly, persons with disabilities and individuals with chronic illnesses
• Never leave young children, elderly or pets in a closed parked vehicle for any period of time
