Environment Canada says weather conditions are prime for the development of severe thunderstorms throughout parts of southwestern Ontario on Sunday.
At around 3 p.m., the weather agency issued a severe thunderstorm watch for parts of Windsor-Essex, Chatham-Kent and Sarnia-Lambton counties.
Just after 8 p.m., London-Middlesex and Elgin County were placed under a severe thunderstorm watch. Western Middlesex County and West Elgin County was upgraded to a thunderstorm warning at 8:25 p.m.
By 9 p.m., the warnings for Windsor-Essex, Chatham-Kent, and Western Lambton counties had been downgraded back to severe thunderstorm watches.
“A line of thunderstorms has developed over Lower Michigan and is expected to move into extreme southwestern Ontario late this afternoon or early this evening,” read a statement from Environment Canada.
Meteorologists say this system has the potential to bring strong wind gusts of up to 110 kilometres per hour, heavy rainfall, and dime to nickel sized hail. The development of a tornado is also possible.
The watch is expected to remain in effect throughout Sunday afternoon and into the evening.
