If you’re leaving the house, you’ll want to have your rain boots on and an umbrella in hand.
A rainfall warning continues for London and surrounding areas with up to 100 millimetres of rain expected.
Environment Canada issued the warning since Tuesday for London, Parkhill, Strathroy, Komoka and Middlesex County.
The weather agency said rainfall amounts ranging from 75 to 100 millimetres are expected by early Thursday morning, with a few areas possibly reaching 125 millimetres.
“Heavy downpours can cause flash floods and water pooling on roads,” said Environment Canada in a statement. “If visibility is reduced while driving, turn on your lights and maintain a safe following distance.”
The agency predicted the heaviest rainfall for Wednesday evening with rates of 15 to 25 millimetres per hour.
Environment Canada said the widespread rainfall is due to a cold front and a moisture laden low pressure system that will arrive from the American Midwest.
Showers are expected to continue through Thursday with temperatures as low as 10 C.
