Snow Squall Warning
Alerts: White River - Dubreuilville - Wawa
Snow Squall Warning
Issued at 8:18 AM EST Wednesday 7 December 2011
Summary
Snow squalls with whiteout conditions continuing today.
Details
Cold southwest winds over the relatively warm waters of Lake Superior have created favourable conditions for snow squalls. Snow squalls are affecting the eastern shore of Lake Superior this morning. Winds will gradually veer slightly to a more westerly direction, bringing the snow squalls into regions south of Wawa by early this afternoon. Local snow amounts of 15 cm are possible in the White River, Wawa, Dubreuilville and Agawa regions, local before the snow squalls end this afternoon. The snow squalls will drift south of Lake Superior park and affect areas from Montreal River to Searchmont later this afternoon. Local snow fall amounts of 10 cm are likely. Snow squalls will become disorganized tonight as a cold front sweeps across Lake Superior. However, as the winds become northwest Thursday morning, snow squalls are expected to redevelop and persist into Thursday evening. An additional 20 cm are expected Thursday, with higher amounts possible. The strong southwest winds will also result in blowing snow leading to local whiteout conditions. Driving conditions will deteriorate quickly tonight. Motorists should adjust travel plans accordingly and be prepared for sudden near zero visibility from blowing snow and bursts of heavy snow.
