‘Dangerously hot and humid’ conditions are expected to continue through to Sunday, as Sarnia-Lambton remains under a heat warning amid scorching temperatures and humidex values stretching into the 40s.
“A prolonged heat event continues through Sunday,” Environment Canada’s latest weather warning states, forecasting ‘dangerously hot and humid conditions for the region.
Humidex records will be challenged all across Ontario, and will be similar in magnitude to the June-July 2018 heat wave event, according to the Weather Network.
“As we continue to move in the direction of a warming world, extreme heat events like these are expected to increase in frequency.
“Air quality in the region will likely suffer due to this stagnant, humid air mass.”
Lambton Public Health extended its heat warning, Wednesday, stressing that vulnerable populations — older adults, young children, people with chronic illnesses, pregnant individuals, people who work outdoors, and individuals who are underhoused or experiencing homelessness and are without access to air conditioning — are most at risk.
Extended Heat Warnings are issued when a heat warning continues beyond two days, the health unit noted.
Daytime highs are expected to be 32 to 35 degrees Celsius with humidex values of 40 to 45, Environment Canada stated, adding there will be little relief overnight with lows of 20 to 24 degrees Celsius expected, with humidex values of 28 to 35.
Temperatures and humidex values may be several degrees cooler near the shores of the Great Lakes.
Never leave people, particularly children, or pets inside a parked vehicle, and watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
