Biggest Wave EVER on the Great Lakes!

Very strong winds in Upper Michigan downed trees and powers lines, leaving thousands of customers without power.  The Alger Co. Sheriff is urging residents to stay home.  A man and women got swept off Black Rocks by the waves of Lake Superior on Tuesday afternoon around 1:35 p.m. The U.S. Coast Guard helicopter from Traverse City has arrived in the area to assist with the rescue operation.  Marquette City Police have advised that anyone who attempts to go out to Presque Isle Island could be arrested.  Several shelters have been opened to aid those without power.  Wow!  Check out this picture of a HUGE wave on Lake Superior!

  Here’s a power outage map at 7 pm, showing many of the outages in the Keweenaw Peninsula and east and west of Marquette.  Winds at the Lake Superior shore gusted to over 60 mph.

Here’s peak winds in the U.P. today.

  This is a record of the wind at the Stannard Rock, Lighthouse.  The peak wind this morning was 67 knots – that’s 77.1 mph (hurricane force).  The sustained wind was 57 knots or 65.6 mph.

If you don’t know about Stannard Rock.  It’s a lighthouse on a tiny reef 24 miles east of the Keweenaw Peninsula of Upper Michigan, the most distant lighthouse from land in the U.S.  The lighthouse was completed in 1883.  The lighthouse was manned for 78 years and had the nickname “The Loneliest Place in the World”.

The lighthouse was automated in 1962 and the Coast Guard still maintains it as an active aid to navigation. It’s closed to the public and can only be viewed by boat or airplane. It was listed on the National Register of Historic Places in 1971.  The weather is fierce out here and it’s a testimony to the builders that it still stands 134 years after it was built.

This is data from the buoy several miles off Munising.  The bouy recorded a wave of 28.9 feet at 9:30 am this (Tue.) morning.  The wind at the time was north at 42.46 mph (peak gust was not available)

Here’s a record of waves at the buoy.  Note how quickly the waves increased and how easily a boat could get in trouble and maybe not get back to shore as the wind and waves ramped up.  Here’s a picture of waves at the shore at Au Train today.

The strong north wind, combined with high lake levels, has resulted in flooding along the Lake Superior shore and significant beach erosion.

M-26 was closed in Keweenaw County between these markers … high winds, waves bringing water and debris onto roadway.  Here’s video of the waves on the Lake Superior shore.

Snow is falling over much of the U.P. with up to 4″ accumulation possible tonight.

  Here in West Michigan, waves were washing over the piers and breakwaters.  This pic. is South Haven.  Waves this evening have reached 12.1 ft. at the S. Haven buoy and 11.5 ft. at the Port Sheldon buoy.

There was a gust to 74 mph at the White River Lighthouse in NW Muskegon Co. this PM.
