You’ll want your rain boots and an umbrella handy for Saturday evening.

Environment Canada has issued a special weather statement for the London region, calling for heavy rain Saturday night into Sunday morning.

What used to be Tropical Storm Olga, is now just a wet low pressure system heading straight for Southwestern Ontario.

The weather agency says total rainfall amounts of 30 to 40 mm are possible, with the heaviest rain falling overnight Saturday.

Gusty easterly to southeasterly winds —up to 60 km/h— are also in the forecast.
