Winter storm watch in effect for:

• Sarnia – Petrolia – Western Lambton County
• Watford – Pinery Park – Eastern Lambton County

Potential winter storm late Friday into Saturday morning.

A Texas low is expected to bring heavy snow and strong winds to a large swath of southern Ontario. There remains a great deal of uncertainty across the region regarding snowfall amounts for this system. Due to the uncertainty we cannot confidently upgrade this alert to a warning at this time.

Snow is expected to begin late Friday afternoon or early evening and quickly become heavy at times. Heavy snow in combination with strong easterly winds may create reduced visibility and hazardous travel conditions. Temperatures in some areas across the region may remain above zero during the snowfall, which may limit accumulations slightly.

Winter storm warnings or winter weather travel advisories may be issued as the event draws nearer.

Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or tweet reports using #ONStorm.
