Thursday is going to be a very wet day in the London area.
Environment Canada has issued a rainfall warning for the region. Forecasters say we can expect 20-30mm of rain on average.
But some areas could see up to 50mm if forecasted thunderstorms develop.
Forecasters say the rain could be enough to cause flooding in low-lying areas. They advise people to stay away from rivers, creeks, and culverts.
