Environment Canada is forecasting a multi-day heat event starting Tuesday, June 30th and continuing into Friday, July 3rd. Daytime highs will be as high as 34 degrees Celsius, with humidex values near 41. Overnight low temperatures are expected to be near 22 degrees Celsius. This heat event will occur over the Canada Day holiday, and Southwestern Public Health advises preparing for all holiday activities accordingly.

Residents in Elgin County, Oxford County, and the City of St. Thomas are recommended to monitor the weather forecast to evaluate the risk of exposure to heat as conditions could change. Visit Environment Canada's website for the most up-to-date information.

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.

• 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
