Potential ice storm for parts of Southern Ontario Saturday and Sunday.
Heavy rain potential later Sunday and Sunday night.
A significant freezing rain event is looking increasingly likely for portions of Southern Ontario Saturday and Sunday as a slow-moving low pressure system approaches the area. Precipitation may start as rain, but increasing northeasterly winds will draw colder air from an arctic high pressure system to the north, resulting in a changeover to freezing rain. A few rounds of precipitation are likely during this period with a significant threat of prolonged freezing rain in some areas.
At this point, there is still considerable uncertainty with regards to which areas may be most affected. However, this has the potential to be a major ice storm for some regions with ice accumulations in excess of 20 millimetres possible. Ice accumulations of this magnitude combined with gusty winds to 60 km/h may result in widespread power outages due to fallen tree limbs and power lines.
Travel is also expected to be hazardous.
