Weather Warning: Snow squall warning in effect for Manitoulin Island

Snow squall watch in effect for:

  • Manitoulin Island

Conditions are expected to become favourable for snow squalls to develop off Northern Lake Huron beginning this evening and continuing through Wednesday.

Local snowfall amounts of near 15 cm are possible in the heaviest snow squalls.

Strong and gusty southwesterly winds are also expected to whip up the freshly falling snow, resulting in very low visibility in blowing snow.

Motorists should expect hazardous driving conditions tonight and Wednesday, and be prepared to change travel plans accordingly.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
