A lake-effect storm continued to blanket parts of the Great Lakes region with snow on Saturday, closing highways on one of the biggest travel weekends of the year and prompting Gov. Kathy Hochul of New York to declare a state of emergency on Friday in 11 counties.

The snowstorm, which is expected to last through Tuesday, is forecast to bring more than 40 inches to some parts of New York, the National Weather Service said early Saturday.

Up to six feet of snow could bury counties east of Lake Erie before the storm passes, forecasters said, warning that some counties could be brought to a standstill.

The heaviest snow totals on Saturday morning were on the southern and northeastern shores of Lake Erie and east of Lake Ontario, where intense snow bands could continue to bring up to three inches an hour.

Nearly three feet of snow had already accumulated in Perrysburg, N.Y., about 30 miles south of Buffalo.

In Michigan’s Upper Peninsula, Sault Ste. Marie had recorded 23 inches of snow on Saturday morning, and parts of the region were expected to get an additional one to two feet.
