DULUTH (AP) - An early December storm has dumped more than 20 inches of snow in parts of northeastern Minnesota.

As much as 22 inches of snow had fallen just north of Two Harbors by 2:30 p.m. Tuesday. Some Duluth neighborhoods had received more than 16 inches of new snow, and some streets remain unplowed and unpassable.

The National Weather Service says another foot or more could fall Wednesday before the storm moves east and is replaced by arctic cold.

Duluth police have handled 50 crashes since the snow began Monday.

The heavy snow has canceled or delayed school in some northeastern Minnesota communities.

A gale warning is posted for Lake Superior. The weather service has issued a winter storm warning for the region through late Wednesday.
