Heat Warning (3)

Environment and Climate Change Canada has issued a Heat Warning for Waterloo Region and most of Southern Ontario. Heat and humidity will arrive today with high temperatures reaching near 31 or 32 degrees and lasting until Thursday. Night time lows will also be warm in the 20 to 23 degree range tonight and Wednesday night.

A Heat Warning is issued when hot temperatures and humidex values are severe enough to affect all residents that may be exposed outside for an extended time. This warning is issued for Waterloo Region when Environment and Climate Change Canada forecasts at least two days with a day time temperature of 31°C or above and the night time temperature is 20°C or above, or two days with a humidex of 40°C and above. The risk of exposure to these temperatures and humidex may result in heat rash, heat cramps, heat exhaustion, or heat stroke.

All residents have the potential to be affected by extreme heat-related weather conditions, depending on the length of time exposed and exertion levels. These risks are especially high for: older adults (over the age of 65), infants and young children, people with chronic illnesses, people who work or exercise in the heat, people who are socially isolated or are experiencing homelessness, people who cannot care for themselves, and people without access to air conditioning.

All residents are urged to take the following actions:

1. Drink plenty of cool liquids, especially water, before feeling thirsty. Avoid drinks that are high in sugar, caffeine and/or alcohol.
2. Take cool showers or baths until you feel refreshed.
3. Reschedule or plan outdoor activities during cooler parts of the day.
4. Take a break from the heat by spending a few hours in a cool place.
5. When outside, seek shade.
6. Block the sun out by closing awnings, curtains, or blinds during the day.
7. Never leave people or pets in your care inside a parked vehicle or in direct sunlight.

Frequently visit neighbours, friends and older family members, especially those who are chronically ill or live alone, to make sure that they are cool and hydrated.
