A major ice storm is likely this weekend across a broad swath of southern Ontario, extreme southern Quebec and the Fundy Shore, says Chief Meteorologist Chris Scott.
Freezing Rain WarningIssued at 3:48 PM EST Friday 20 December 2013
Periods of freezing rain tonight. Potential for Major ice storm starting late Saturday afternoon.Details
A significant frontal boundary from Sarnia to near Hamilton eastwards across Lake Ontario is expected to remain fairly stationary for the next 36 hours. North of this front a disturbance generated freezing rain across a wide swath of Southern Ontario today and it continues to work its way eastwards up to the Quebec border. Freezing rain amounts ranging from 3 to 8 mm likely occurred. A key concern remains the next disturbance which is expected to track from Texas and move towards the Lower Great Lakes Saturday evening. The moisture associated with this low is substantial and has the potential to produce a major freezing rain storm over portions of Southern and Eastern Ontario. Current information suggests 20 to 30 mm of freezing rain is possible starting Saturday afternoon and continuing Sunday morning. As a result, ice accumulation on trees and power lines could potentially create widespread power outages and downed trees. Driving conditions on untreated roads could become very hazardous. Motorists and pedestrians should exercise caution and adjust travel plans accordingly. In addition regions near Lake Erie which manage to have temperatures above zero could experience significant rainfall amounts Saturday night into Sunday morning. At the moment amounts could range from 15 to 25 mm. Please monitor the latest forecasts and warnings from Environment Canada at www.weatheroffice.gc.ca.
