Calgary and several communities in Rocky View County were under severe thunderstorm warnings Monday afternoon as strong winds, heavy rain and hail possibly the size of toonies could fall across the region.

Warnings from Environment Canada said loonie-sized hail had already been reported as of 4:20 p.m. and bigger hail could come. The warning for Calgary was lifted by 5:45 p.m.

“Heavy downpours can cause flash floods and water pooling on roads,” Environment Canada said. “Large hail can damage property and cause injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles.”

Three men were forced to leave their home in northeast Calgary after lightning struck a power pole, officials said.

Enmax crews were called to 6617 McKnight Blvd just before 6 p.m., however, power was still on as of 5:55 p.m.

The thunderstorms came as much of Alberta was under a heat warning after days of hot temperatures.

However, the heat warning ended early Tuesday morning for much of the province, including Edmonton and Calgary. The temperature was expected to reach 24 C to 25 C for both cities on Tuesday.

The warning remained in place for some southern Alberta communities, including Brooks, Drumheller and Medicine Hat.

Over the weekend, several areas in northern Alberta were already under a heat warning.

Early Sunday morning, Edmonton and areas west of the city were added to the list.

Air quality

In some parts of Alberta, heat won’t be the only issue. Hazy conditions will persist over several areas and the Air Quality Health Index will increase to moderate levels.

Haze is common when pollution and dust are stagnant in the atmosphere.

Most people won’t be affected, but those with breathing problems should reduce strenuous outdoor activities, as recommended by Environment Canada.

Several parts of Alberta had an air quality level of 4 – or moderate – on Sunday and Monday, including Edmonton and Calgary.
