A heat warning has been issued for Ottawa by Environment Canada.
The weather agency issued the warning Saturday afternoon, saying a hot and humid airmass is expected to will reach southern Ontario Sunday. It add that it may continue into Tuesday.
During the expexted heatwave, the temperatures are expected to rise between 29 C and 31 C — humidex values near 40, says the weather agency.
However, at night, the capital will have a little relief, as lows near 20 C are expected.
“Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category,” said Environment Canada in a statement Saturday.
The heat warning is expected to end on Tuesday, as a cooler airmass is forecasted to arrive Tuesday night, according to the weather agency.
People are asked to limit their exposure to direct sun, to shade themselves and to drink plenty of water to decrease the chances of dehydration.
“Never leave people, particularly children or pets inside a parked vehicle. Ask a health professional, such as a pharmacist or physician, how medications or health conditions can affect your risk in the heat,” said the weather agency.
