Prolonged Heat Event to Last Most of This Week!

Brockville – Environment Canada has issued a Heat Warning for Brockville, Leeds-Grenville, Smiths Falls, & Lanark which is expected to begin on Monday, June 17th and last most of this week.

A prolonged heat event will begin on Monday with dangerously hot and humid conditions expected through most of the week.

Daytime highs on Monday through much of the week are expected to be 30 to 35 degrees Celsius with humidex values of 40 to 45. There will be little relief overnight as lows are expected to be 18 to 23 degrees Celsius with humidex values of 26 to 30.

Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high-risk category.

Extreme heat can affect everyone’s health.

The health risks are greater for older adults, infants and young children, pregnant people, people with physical and/or mental illnesses, and people with disabilities or mobility issues.

Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

Heat stroke is a medical emergency! Call 911 or your local emergency number immediately if you or someone you are caring for has a high body temperature and is confused, has stopped sweating or has become unconscious.

While waiting for help, cool the person right away: move them to a cool place, apply cold water to large areas of the skin and fan the person as much as possible.
