At 5:30 PM EDT, meteorologists are tracking a line of severe thunderstorms capable of producing large hail, damaging winds and heavy downpours. The line extends from about near Halton to around St Thomas and is moving southeastward at about 50 km/h. There is also another thunderstorm ahead of the line approaching St Catharines. Hail with diameter 2 to 4 cm and wind gusts to 110 km/h are possible with these thunderstorms, as well as heavy downpours giving up to 50 mm of rain in less than one hour. There is also a slight risk of a tornado.
Emergency Management Ontario recommends that you take cover immediately, if threatening weather approaches.
Strong wind gusts and hail can damage property and cause injuries. Local downpours can cause flash floods.
Go indoors and move away from windows and skylights. Avoid areas of the building that could be affected by falling debris such as tree limbs. Stay on the lower floor of your home or building and if the storm is particularly severe go to the basement.
Avoid driving through water on roads. Even shallow fast moving water across a road can sweep a vehicle away.
Remember, severe thunderstorms can produce tornadoes.
In Canada, lightning kills up to 10 people every year. Remember, when thunder roars, go indoors.
