Calgary among areas that could be hit with heavy rain, hail as thunderstorm watch issued
CBC
Rain is expected to continue in Alberta this weekend, with severe thunderstorm warnings and watches in effect for the city of Calgary, along with much of the province's central and eastern portions.
Environment and Climate Change Canada has issued a severe thunderstorm watch — meaning conditions are favourable for the development of a thunderstorm — for these areas:
The watches, issued around 7 a.m. Saturday, said thunderstorms will continue to develop later Saturday morning. Some of these thunderstorms could produce heavy rain, strong winds and large hail, Environment Canada said.
A thunderstorm warning for Hanna, Alta., and Lloydminster, Alta., and their surrounding areas, was downgraded to a thunderstorm watch around 10:30 a.m.
It warns that large hail can damage property and cause injury, and that strong wind gusts could toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles.
"Remember, severe thunderstorms can produce tornadoes," the alert read.
"Heavy downpours can cause flash floods and water pooling on roads. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors."
On Friday the City of Calgary rescinded its state of local emergency, which had gone into effect on Monday, as the city braced for significant rainfall.
Mayor Jyoti Gondek said Friday an approaching weather system was tracking farther south than originally anticipated.
Several days of rain, plus mountain snow melt runoff, had swollen the Bow and Elbow rivers in Calgary.
Although river levels are high, the risk of flooding in Calgary has passed for now, Gondek said, and the order is no longer needed.
"We are still in the midst of flood season … please make sure you are staying safe," she said.
Some provincial parks remain closed because of high water levels. The government continues to post updates on those here.
