Snow squall watch in effect for:
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow, and snow will quickly accumulate.
Snow squalls will likely form to the lee of Lake Superior on Sunday into Sunday night as northwesterly winds bring colder air into the region. Local amounts of over 15 cm within a 12-hour period are possible.
Travel may be hazardous due to sudden changes in the weather.
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.
