Rainfall warning
West of the city, three regions are under heavy rainfall warnings.
“Extremely heavy” rain is expected in areas around Grande Prairie, Beaverlodge, Valleyview, Hinton, Grande Cache, Peace River, Fairview, High Prairie and Manning.
“So far, reports of 50 to 86 mm of rain has fallen in the last 24 hours,” the warning states. “Widespread rainfall totals of 70 to 90 mm are expected as heavy precipitation continues to impact the region.
“Higher amounts in excess of 125 mm are possible along the eastern slopes of the foothills and along the higher terrain near Grande Prairie.
“Enhanced precipitation amounts are also likely under slow moving thunderstorms. Heavy rainfall amounts are expected to lessen by Saturday evening.”
The downpours were expected to cause flash floods and water pooling on roads. The floods could be enough to sweep away bridges, culverts, buildings and people. Residents were asked to stay away from low-lying areas and be ready to move to higher terrain if needed.

A trough of low pressure is expected to trigger thunderstorms. A few of these thunderstorms could become severe, according to Environment Canada.
