The Windsor-Essex County Health Unit has issued an extended heat warning for the week that is expected to last until Friday as temperatures are predicted to stay above 30 C.
Environment Canada says people should be prepared and take cover if threatening weather approaches. It says to take the following actions if there is a tornado or tornado warning:
Go indoors to the lowest floor, away from outside walls and windows.
Leave mobile homes, tents, trailers and vehicles and move to a stronger structure if you can.
If you have no other options, lie down in a low area and protect your head from flying debris.
