ENVIRONMENT CANADA
********************************
Snow squall warning replaces snow squall watch for:
    •    Sault Ste. Marie - St. Joseph Island
    •    Searchmont - Montreal River Harbour - Batchawana Bay
    •    Agawa - Lake Superior Park
    •    Wawa - Pukaskwa Park
    •    Blind River - Thessalon
    •    Elliot Lake - Ranger Lake
    •    Espanola - Killarney
    •    Manitoulin Island

Current details:
Snow squalls continue, with the heaviest snowfall expected tonight.

Hazards:
Locally heavy snowfall with accumulations near 30 cm.
Peak snowfall rates of 2 to 5 cm per hour.
Very poor visibility at times in heavy snow.
Power outages possible due to the heavy wet nature of the snow.

Timing:
Continuing through Wednesday night, with the heaviest snowfall expected tonight.

Discussion:
Lake effect snow squalls off Lake Superior have moved into the area, mainly north of Sault Ste. Marie. These snow squalls are expected to move north out of the area this afternoon. However, snow squalls off Lake Michigan will move in this evening as a low pressure system moves across Lake Superior, enhancing snowfall amounts. Snow squalls will then sweep south on Wednesday, moving out of the area Wednesday night.

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 possible.

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.
