Weather warnings updated as much of Ontario braces for ice storm

Environment Canada has updated its weekend weather warnings for much of the province.

In north part of Durham and York regions, significant rain and freezing rain is expected through the day Saturday (Jan. 11) and Sunday.

“Rainfall, combined with melting snow, is expected. The frozen ground has a reduced ability to absorb this rainfall. A moisture laden low from Texas will continue to bring a significant heavy rainfall event to Southern and Eastern Ontario Saturday,” reads the warning for the northern communities.

“Total rainfall amounts of 30 to 50 mm are anticipated by this evening, with locally higher amounts possible from isolated thunderstorms this morning. Since the ground is frozen, the winter rainfall warning criterion of 25 mm in 24 hours is being met.”

The rain is expected to turn over to freezing rain by early this evening.

“An extended period of freezing rain, possibly mixed with ice pellets, appears likely before precipitation comes to an end on Sunday morning. Ice accretion of 10 to 20 mm is possible in many areas by Sunday morning,” reads the warning for the northern communities.

“Northwesterly winds gusting to 50 km/h in some areas Sunday morning coupled with possible ice build-up on tree branches and power lines may result in local power outages. Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous. Consider postponing non-essential travel until conditions improve. Ice build-up may cause tree branches to break. Utility outages may occur.”
