Environment Canada has issued a heat warning for most of Southwestern Ontario, including Oxford County that is expected to last through Wednesday.
OXFORD COUNTY - Environment Canada has issued a heat warning for most of Southwestern Ontario, including Oxford County.
Extreme heat is expected for Tuesday through Wednesday. A hot air mass approaching the area will bring daytime temperatures in the low thirties over the next couple of days. With increasing humidity on Wednesday, humidex values are expected to creep in the mid to high thirties. Lows between 20 and 22 degrees Celsius are also expected Tuesday night.
Temperatures will cool off Wednesday night as Tropical Depression Cristobal approaches Ontario.
Extreme heat affects everyone however the risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
During a heat event, members of the public should:
- Limit time in the sun when the UV Index (ultraviolet ray strength) is most intense, between 11am - 4pm.
- Take cool showers or baths. Electric fans improve air circulation but will not prevent heat-related illness.
- During extreme temperature conditions, stay indoors and if possible, stay in an air conditioned place.
- Be aware of signs and symptoms of heat cramps, heat exhaustion, and heat stroke. Follow first aid procedures promptly.
- When in the sun, wear a wide-brimmed hat (or with back flap), UV protective sunglasses, loose-fitting long shirts and pants. Seek shade when outside, especially during midday.
- Apply Sunscreen with SPF 30 (or higher), 20-30 minutes before going outside to ensure absorption. Reapply every 2-3 hours.
