On its Facebook page Superior Angling Co. out of Duluth Minnesota issues the following statement on waves expected on Lake Superior today.
34-foot waves are expected Thursday on Lake Superior.
Let's take a moment to put that into perspective.
Hurricane Sandy, the largest Atlantic hurricane on record, produced maximum wave heights of 13 metres in the open oceans, which is equivalent to 42 feet.
These waves are forecasted to be just 8 feet smaller than the largest Atlantic hurricane on record, and this is on a lake, with no hurricane present.
We have been watching NOAA wave heights for many, many years and have never seen a 34-foot wave in the forecast. May the good Lord watch over any mariner who has to be on the water these next few days. Stay safe.
