A rainfall warning has been issued for Toronto and the GTA ahead of a fall storm that is expected to dump 45 to 55 millimetres of rain on the region between tonight and Wednesday evening.

Environment Canada says the storm is the result of a low pressure system that contains moisture from the remnants of Hurricane Patricia.

There is a possibility of pooling on roads and washouts near rivers, creeks and culverts due the heavy rain, the weather agency says.

High winds could also be powerful enough to damage trees and cause local power outages.

“A large shield of rain associated with this storm is forecast to spread into Southwestern Ontario tonight and reach the Golden Horseshoe area by Wednesday morning,” a special weather statement issued earlier on Tuesday reads. “The rain will likely become heavy at times as the low pressure area deepens.”

In advance of the storm, the City of Toronto has dispatched Transportation Services staff to clear catch basins and is calling on residents to clear leaves and other debris from eavestroughs and downspouts.

Residents who are concerned about potential flooding are also being instructed to move their valuables to higher ground and to ensure that cleaning products, paint or other chemicals that could contaminate the floodwater are not stored on the floor.
