Freezing rain warning for
Major ice storm likely starting this afternoon or evening into Sunday morning.
A significant frontal boundary from near Windsor to near Hamilton eastwards across Lake Ontario is expected to remain fairly stationary for the next 24 hours. South of this front periods of rain are likely today before changing over to freezing rain overnight. North of this front, a mixture of rain, periods of freezing rain or freezing drizzle are possible today.
The next disturbance over Texas will track towards the Lower Great Lakes this evening. The moisture associated with this low is substantial and will likely produce a major freezing rain storm over portions of Southern and Eastern Ontario starting late this afternoon or this evening. Freezing rain may be heavy at times tonight, with 20 to 30 mm of freezing rain possible.
As a result, ice accumulation on trees and power lines could potentially create widespread power outages and downed trees or tree limbs. Driving conditions on untreated roads could become very hazardous. Motorists and pedestrians should exercise caution and adjust travel plans accordingly.
