After a week of sweltering temperatures in most of western Canada, many mountains will see sub-zero temperatures that will bring snow. Many places in Canada, including Toronto, are currently under a heat warning.
Winter storm warnings have been issued for areas of Banff and Jasper National Parks along Highway 93, urging residents to prepare for hazardous winter conditions. Snow is also expected at high elevations in B.C.
“Consider postponing non-essential travel until conditions improve,” says Environment Canada in the warning. “Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow.”
As much as 30 to 40 cm of snow could fall by Tuesday. That means that anyone going to the mountains for climbing or hiking should be prepared to change plans.
Skiers are surely stoked about the forecast, but with high winds and blowing snow, there will be avalanche danger in many areas.
In many of the valleys, there are rainfall and flash flood warnings. “Heavy downpours can cause flash floods and water pooling on roads. Don’t approach washouts near rivers, creeks and culverts,” said Environment Canada.
