With freezing rain expected to hit Brampton and the rest of Southern Ontario Thursday Morning, Environment Canada warns of a potential ice storm over the weekend.

While freezing rain is expected Thursday, a much more threatening slow-moving low-pressure system is moving into the area starting Saturday and into Sunday.

“This has the potential to be a major ice storm for some regions, with ice accumulations in excess of 20 millimetres possible,” said Environment Canada in a special weather statement issued Wednesday.

“Ice, combined with winds up to 60 km/h, could result in power outages due to fallen tree limbs and power lines, and will make travel hazardous,” the statement warns.

Areas around Lake Ontario and the 401 are expected to have milder temperatures on Saturday which may result in less freezing rain.

The ice, combined with gusty northeast winds could cause power outages due to fallen trees and power lines.

As of now, it isn’t clear which areas will be most affected by the freezing rain.
