Environment and Climate Change Canada is warning of a severe thunderstorm that is tracking through southern Manitoba for the rest of the day. 

As of 3:30 p.m. today, Environment and Climate Change Canada has issued a severe thunderstorm watch where Manitobans could experience hail the size of baseballs, wind gusts in excess of 100 km/h and approximately 50 mm of rain.

"We like to use the cupcake analogy for watches and warnings," says Terri Lang, a meteorologist with Environment and Climate Change Canada. "When we talk about a watch, whether it be a severe thunderstorm or tornado, that means all the ingredients are there to make a severe thunderstorm or tornado. When we have a warning, it means all the conditions have come together and that thunderstorms or tornados are imminent or occurring."

Northwestern Ontario is currently under a severe thunderstorm warning.

From Environment Canada:

Very large hail can damage property, break windows, dent vehicles and cause serious injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads.

Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors.
