A prolonged period of significant lake effect snow squalls off Georgian Bay tonight through this weekend. Extremely dangerous travel is expected within these snow squalls.
Local snowfall amounts of 15 to 30 cm by Friday afternoon.
Event total snowfall amounts may locally exceed 75 cm by Sunday.

This evening through Sunday. Snow squalls may drift south of the area for a time on Friday before returning Friday night into Saturday.
Snow squalls are expected to intensify tonight and persist into Friday morning. Gusty southwesterly winds will result in local blowing snow on Saturday.
Gusty northwesterly winds are forecast on Sunday morning as a cold front passes through the area, which will shift snow squalls out of the region.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Road closures are likely.
Consider postponing non-essential travel until conditions improve. If you must travel, keep others informed of your schedule and destination and carry an emergency kit and mobile phone. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.
