The current Environment Canada forecast is calling for a spike in temperatures Friday, with an expected high of 31º Celsius and humidex values reaching 35. These conditions meet the Middlesex-London Health Unit’s criteria for issuing a one-day Heat Alert. The overnight temperatures heading into Saturday are expected to offer a reprieve, dropping to 19º Celsius. Based on the current forecast, this Heat Alert will remain in effect until Saturday morning, when the daytime high is expected to reach 29º Celsius.
The Health Unit issues Heat Alerts when one or more of the following criteria are met:
- Environment Canada issues a forecast calling for a day-time high of 31º Celsius or higher and a forecast low of 20º Celsius or higher, or;
- Environment Canada issues a forecast calling for a Humidex of 40º Celsius or higher.
The Health Unit recommends the following tips to avoid the risks of heat-related illness:
- Drink plenty of water and natural juices throughout the day, even if you don't feel very thirsty.
- Never leave a child or pet in a parked car or sleeping outside in direct sunlight.
- Avoid drinking alcoholic beverages, as well as coffee and cola.
- When possible, avoid spending too much time outdoors. If you must be outside, seek shade as much as possible. Plan outdoor activities in the early morning or evening.
- Wear a wide-brimmed hat when outdoors.
- Keep shades or drapes drawn and blinds closed on the sunny side of your home.
- Avoid turning on electric lights in your home.
- Take a cool bath or shower periodically or cool down with cool, wet towels.
- Avoid eating heavy meals and using your oven.
- Avoid intense or moderately intense physical activity.
- Use fans to draw cool air at night, but do not rely on a fan as a primary cooling device during extended periods of excessive heat.
- Reduce the use of personal vehicles, stop unnecessary idling; avoid using oil-based paints and glues, pesticides, and gas-powered small engines.
