Environment Canada has raised its winter storm advisory for Newmarket and area from a watch to a warning as it cautions that rapidly accumulating snowfall will make driving conditions treacherous.
The storm is expected to impact a large swath of southern Ontario Friday night and continue into Saturday.
The full weather warning is as follows:
Warnings
4:51 PM EST Thursday 02 March 2023
Winter storm warning in effect for:
- Newmarket - Georgina - Northern York Region
- Pickering - Oshawa - Southern Durham Region
- Uxbridge - Beaverton - Northern Durham Region
- Vaughan - Richmond Hill - Markham
Winter storm expected Friday night.
Hazards:
Significantly reduced visibility due to heavy snow and blowing snow.
Total snowfall accumulations of 15 to 25 cm.
Snowfall rates up to 4 cm/h possible.
Rapidly accumulating snowfall creating hazardous travel conditions.
Timing:
Friday evening into Saturday morning.
Discussion:
A Texas low is expected to bring heavy snow and strong winds to a large swath of southern Ontario. Snow will begin Friday evening and quickly become heavy at times. Heavy snow in combination with strong easterly winds will create significantly reduced visibility and hazardous travel conditions.
Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Prepare for quickly changing and deteriorating travel conditions. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.
