Hurricane Sandy, now downgraded to a "Post-Tropical Cyclone", continues to wreak havoc along the eastern coast of the United States and Canada after making landfall yesterday afternoon. The sheer size of the storm has residents wondering, "How is Sandy effecting Duluth and Superior?" Find out how Sandy is impacting the Twin Ports.

The strong wind from the low pressure system called Sandy is creating hazardous conditions and has all shipping traffic ground to a halt on the four eastern Great Lakes.  Wave conditions as near as the Lake Michigan shoreline of Wisconsin has wave heights reaching near 30 feet at times. The strong wind is circulating counter clockwise around the center of the storm, as it passes over Pennsylvania and heads northeast (see below). The worst conditions currently expected include waves up to 32 feet in areas on Lake Huron and southern Lake Michigan.

Closer to home, the wind from Sandy has prompted the National Weather Service to issue a small craft advisory entire Minnesota North Shore and Wisconsin South Shore. Wave heights between 3 and 5 feet are expected along the entire Minnesota shoreline and along the Wisconsin shoreline between Superior and the Bayfield Peninsula. Along the Peninsula and east, wave heights are expected between 4 and 7 feet. The eastern half of Lake Superior is under a Gale Warning, with wave heights up to 18 feet possible. See the map below.

Warnings and Advisories Along Lake Superior

Advisories for the western part of Lake Superior, near the Twin Ports, are expected to expire tonight. The eastern half of Lake Superior and the Eastern Great Lakes could see advisories for a few days while Sandy slowly makes her way north and east, back out over the Atlantic Ocean.

While weather conditions are by no means severe in the Twin Ports region, shipping traffic and business impacted by shipping are being influenced by the mega storm. It may be a matter of a couple of days before the full Great Lakes shipping route will be reopened. Many ships remain anchored in various places around the Great Lakes, waiting for the wind to subside. As of right now, luckily, no reports of issues for those on ships on the Great Lakes have come in.
