High temperatures expected across Southern Ontario this weekend: meteorologist
Environment Canada is expected to issue a heat warning for southern Ontario, with hot conditions potentially lasting until Tuesday, a meteorologist with Environment Canada told CBC Toronto.
Daytime temperatures of over 30 C are expected throughout southern Ontario, particularly along the Highway 401 corridor between Windsor and Ottawa, Crawford Luke said.
The hottest days are expected to be Sunday and Monday, reaching about 33 C. Humidity levels are expected to be slightly less severe this weekend compared with previous heat waves this summer, making it feel like high 30s, potentially low 40s, he said.
Nighttime lows of around 20 C will provide little relief, particularly in big cities like Toronto due to the "urban heat island effect," Luke said.
Hot temperatures are expected to continue throughout the month, though he said next week could cool off slightly.
"It's entirely possible that we get … another heat warning or heat wave later in August or even into September," Luke said.
Advice to help beat the heat
Environment Canada is advising people to limit time outside during the hottest hours of the day, between noon and 7 p.m. and to drink water often, Luke said.
If possible, he said outdoor workers should try to take more frequent breaks, drink more water and try to periodically get under the shade or go indoors.
"Take it easy, listen to your body and don't overdo it," Luke said.
People are advised to watch for symptoms of heat stroke. Symptoms can include red and hot skin, dizziness, nausea, confusion and change in consciousness levels.
