Severe thunderstorm warning for 
Caledon continued

At 4:50 EDT, meteorologists are tracking an area of severe thunderstorms extending from southern Lake Huron through Lake Simcoe and the northern GTA, and east northeastward to the southern Ottawa Valley.

These are dangerous storms.  A roof has been reported blown down in the Petawawa area and trees have been blown down.  Wind damage has been reported in Petawawa, Pembroke, Gravenhurst, Bracebridge, Barrie, and Coldwater.

The individual thunderstorms are moving eastward at 80 km/h while the area of thunderstorms is sinking southward at about 30 km/hr.

The thunderstorms are capable of producing damaging winds and large hail as well as the threat for a tornado.
Torrential downpours are also associated.  Some places could see local rainfall amounts of 50 mm in an hour.

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.
