Just as we expected, snow squalls have now developed on the eastern shores of Lake Superior. Widespread accumulation is expected this afternoon and into this evening where the squalls could intensify for several hours before tampering off Saturday.
Snow squall warning in effect for:
Agawa – Lake Superior Park
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls are expected. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
Snow squalls are likely to move in by mid afternoon and continue through Saturday.
Local snowfall accumulations of 15 to 30 cm are expected in these snow squalls. Areas near Montreal River and Batchawana Bay could possibly reach 40 cm.
The combination of strong and gusty winds reaching up to 60 km/h and heavy snow at times will result in a significant reduction in visibility in local blowing snow.
Prepare for quickly changing and deteriorating travel conditions. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. If visibility is reduced while driving, turn on your lights and maintain a safe following distance. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop. Consider postponing non-essential travel until conditions improve.
Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
