Environment Canada has released a severe thunderstorm alert for Metro Vancouver.

Hail, strong winds, and heavy rain may be expected.

Lightning may also strike.

“Remember, when thunder roars, go indoors!” Environment Canada advised.

According to the agency, a cold front will approach the B.C. coast tonight (May 4), creating conditions favourable for thunderstorms.

“Some of these thunderstorms have the potential to become severe in the eastern sections of Metro Vancouver, Fraser Valley, Howe Sound and Whistler,” the agency warned.

Environment Canada recommends unplugging radios and televisions, and listening for weather updates on battery-powered radio.

During thunderstorms, people are advised to stay away from items that conduct electricity, like appliances.

If outdoors during a thunderstorm, take shelter immediately.
