Heat hits with a vengeance in Ontario, Quebec
OTTAWA — Is there anything more Canadian than the duelling images of sweltering city-dwellers and snowshoers?
While those living in southern Ontario and Quebec were warned Monday not to go outside because of summer's first heat wave, revellers at the Whistler Blackcomb Ski Resort in British Columbia were busy sliding down an alpine tube park.
In Ontario and Quebec, temperatures are expected to hover in the low 30s all week, but the humidity will make it seem more like 40 C, said Geoff Coulson, a meteorologist at Environment Canada.
"It's the first real heat wave, in Toronto at least, since back in the summer of 2007," said Coulson. "Southern Ontario and southern Quebec are going take the brunt of it."
While past summers have brought "one-day wonders," this is the first longer stretch of high temperatures in three years, he said.
In Toronto, the medical officer of health on Monday issued an extreme heat alert as temperatures were expected to hit a searing 33 C. A smog advisory also was issued for southern Ontario and some regions of central and eastern Ontario.
"We did have a period of warm conditions, very warm conditions, in late May, but this real, true heat wave (is) kind of the first of the season, so we're also dealing with concerns of acclimatization," said Coulson.
"Folks perhaps may have the tendency to overdo it a bit. The body's not really geared for these high temperatures and high humidex readings just yet."
During an extreme heat alert, residents are encouraged to take breaks in air-conditioned places, drinks lots of water and juice, stay out of the sun and reduce outdoor physical activity during peak afternoon hours.
They are also encouraged to check in on vulnerable people, such as children and the elderly.
They're also encouraged to make sure their pets have access to water and are sheltered from the heat.
Even at night, with temperatures staying in the low 20s, it's going to feel like 30 C because of the humidity, said Coulson.
"These are going to be the tough nights to sleep."
The high humidity in Ontario and Quebec will continue throughout week until it breaks slightly on Friday, said Coulson, when temperatures are expected to fall to the high 20s.
The heat wave is the result of an air mass moving up from the Gulf of Mexico, via a large area of high pressure south of the Great Lakes, Coulson said. The stability of the weather pattern is keeping the forecast steady, and also contributing to the smog advisory because the air is stagnant, he said.
In other parts of Canada, people are living an altogether different summer.
After the second-snowiest winter on record, with almost 1,500 cm having fallen from November to May, the alpine tube park on Whistler Mountain opened June 26 for the first time ever during the summer.
"It's still going strong," said Amber Turnau, a spokeswoman for Whistler Blackcomb.
It is recommended that sliders wear jackets, layered clothing and boots, said Turnau.
"Snow pants, if you have them, would be a good idea," she said. "You don't want to get snow down your pants."
While there is typically a mountain open for summer skiing and training, mountain officials this year recommended snowshoes for those braving the hiking trails.
Temperatures were "warming up" to around 18 C in the valley areas, with cooler weather up on the mountains, said Turnau.
In Vancouver, things were right around where they should be, with an expected sunny high of 20 C on Monday. Temperatures in the B.C. Interior are expected to be much warmer, with places such as Kelowna expected to hit 34 C later this week, although without the humidity of Eastern Canada.
Normal highs for Kelowna are about 26 C, said Coulson.
The Prairie provinces were experiencing cooler temperatures Monday. In Calgary, for example, the high was forecast at 15 C — seven degrees cooler than the nighttime low in southern Ontario and Quebec.
After days of severe weather that brought tornadoes and hail, conditions calmed for southern and central areas of Saskatchewan on Monday, although some areas were forecasting more rain, said Coulson. The high in Regina was expected to hit the high teens and low 20s.
The latest in a series of natural disasters to plague Saskatchewan, Friday's tornado caused significant damage to about 15 homes and cleanup is expected to cost millions.
Meanwhile, 48 wildfires raged in the province's north, said Jeanette Krayetski, Environment Ministry spokeswoman, while in other parts of the province, flooding due to recent heavy rains kept some highways impassable.
In Winnipeg, residents were looking at warm temperatures Monday, about 26, with mid- to low-20s for the rest of the week.
The Maritimes were warm, with highs in Fredericton expected at 27 C, with a chance of showers. Charlottetown was forecast to hit highs in the low 20s, although the East Coast is primed to reach higher temperatures later this week, said Coulson.
Residents of St. John's, N.L., are looking at cool temperatures all week with Monday's high forecast to hit only 13 degrees.
