Much of southern Ontario remains under a heat advisory as temperatures soar once again.
Environment Canada is calling for highs in excess of 30 C for Monday and Tuesday for much of southern, midwestern, and eastern Ontario.
Such conditions are well above normal for the early days of fall, and some areas could set, or break temperature records.
The Perth County Health Unit is reminding people to take care to prevent heat-related illnesses.
Extreme heat can cause dehydration, heat exhaustion, heat stroke and even death. Seniors, infants and young children, and people with chronic illness or who take certain medications, are at a greater risk of suffering from heat-related illness.
During a heat warning, residents and visitors should:
- Drink plenty of cool liquids, especially water - Reschedule or plan outdoor activities during cooler parts of the day - Wear loose fitting, light-coloured clothing made of breathable fabric - Never leave people or pets inside a parked vehicle or in direct sunlight - Take a break from the heat by spending a few hours in a cool place, such as a tree-shaded area, swimming facility, or an air conditioned spot, such as a public building, shopping mall, grocery store, or public library - Take cool showers or baths until you feel refreshed - Prepare meals that don’t need to be cooked in your oven - Block sun out by closing curtains or blinds during the day - Avoid sun exposure. Shade yourself by wearing a wide-brimmed, breathable hat or by using an umbrella.
Environment Canada says the hot and sunny conditions could lead to higher pollution levels in larger cities.
The weather agency says some people could experience coughing, throat irritation, headaches or shortness of breath.
Children, seniors, and people with conditions like asthma are at the greatest risk of suffering from symptoms of the pollution.
The agency recommended to consider postponing strenuous outdoor activities until the air quality statement is lifted.
Forecasters are expecting more seasonal temperatures by Thursday, and much cooler weather by Friday and the weekend.
