Forecasters are again calling for big waves on the Great Lakes, with a maximum wave height of 26 feet possible Thursday on Lake Superior.

The National Weather Service has issued gale warnings for Lake Michigan, Lake Superior and Lake Huron that remain in effect through late Thursday or Friday afternoon, depending on the location.

Sustained winds of 37 knots and gusts of 52 knots from the southwest are expected to whip up 13-foot waves on Lake Superior near Ontonagon. A maximum wave height of 20 feet is possible in the area Thursday evening. Waves will grow larger -- up to 26 feet -- to the east in Eagle River and north at the Canadian border, forecasters say. Isle Royale National Park is included in the warning in effect until 4 p.m. Friday.

There won't be as much wave action on Lake Michigan, where a gale warning is in effect from St. Joseph to Manistee until 4 a.m. Friday. Winds as strong as 40 knots are expected to build waves up to 10 feet Thursday.

The largest waves on Lake Huron will form over the central part of the lake. The warning covers the Saginaw Bay, where waves between 8 and 11 feet are possible. Thursday's warning also includes offshore waters from the Mackinac Bridge south to Port Sanilac. Forecasters say 14-foot waves are expected, and waves building to 20 feet are possible.
