Strong northeast winds will bring large waves along the South Shore through Sunday night as waves on Lake Superior are expected to reach 12-16 feet along the shoreline.

Flooding is expected along the shorelines of Ashland and Iron counties with possible damage to shoreline infrastructure including harbors, beaches and roads near the shore, according to the National Weather Service in Duluth. Winds will reach 25-35 mph, with gusts up to 45 mph. Residents who live on or near the shore should be alert to rising water as well as those traveling along the South Shore through Sunday night, NSW said.

The strong winds will also result in difficult driving conditions, especially for lightweight or high profile vehicles, across the Blatnik and Bong bridges in the Twin Ports. Drivers are asked to use caution while traveling over the bridges.

According to the NWS, northwest Wisconsin can expect light snow and patchy freezing drizzle with snowfall totals of 1-4 inches being possible through Sunday. Highest amounts will be in Price, Ashland, Bayfield and Iron counties where a winter weather advisory is in effect.
