Canadian Ice Service Forcast for April and May (PDF file)
Ice congestion in the Straits, which connects Lakes Huron and Michigan, 87 kilometres south of Sault Ste. Marie, is heavy.
“Depending where you are at, it’s a couple of inches to 18 inches of ice,” said West, who indicated there wasn’t much shipping traffic in the Straits Sunday.
Meanwhile, Coast Guard ice breakers continue their battle to clear a shipping channel in the St. Mary’s River.
The upper river, from the locks to Whitefish Bay in Lake Superior is 100-per-cent covered by ice, with up to 30 inches of plate ice (a solid piece), West said.
The lower St. Mary’s is 80-to-100 per cent covered with six to 24-inch thick ice.
