Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads. Water-related activities may be unsafe due to violent and sudden gusts of wind over bodies of water.
Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
