Environment Canada says conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts and large hail.
Severe thunderstorms are possible this afternoon.
Large hail can damage property and cause injury.
Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Lightning kills and injures Canadians every year.
Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall.
The Office of the Fire Marshal and Emergency Management recommends that you take cover immediately if threatening weather approaches.
The weather office also has a squall warning in effect for the eastern part of Lake Erie.
Hail, lightening and wind gusts up to 40 knots are possible as thunderstorms near Long Point move east through Erie.
