Specifically, on Wednesday, October 27, 2010, buoy no. 45136, operated by Environment Canada, in northern Lake Superior recorded a significant wave height of 26.6 feet (this is average height of 1/3 of the highest waves over an hour), and buoy no. 45002, operated by the National Data Buoy Center (NDBC), recorded a significant wave height of 21. ...
Based on the NWS forecast, Arthur M. Anderson and Edmund Fitzgerald instead started their trip across Lake Superior following the regular Lake Carriers Association route, which placed them in the path of the storm. [147] The NTSB investigation concluded that the NWS failed to accurately predict wave heights on November 10. [148]

The Great Lakes Storm of 1913 was first noticed on Thursday, November 6 on the western side of Lake Superior, moving rapidly toward northern Lake Michigan.The weather forecast in The Detroit News predicted "moderate to brisk" winds at the Great Lakes with occasional rain on Thursday night or Friday for the upper lakes (except southern Lake Huron) and fair-to-unsettled conditions for the lower ...
A lake wind advisory is issued for winds just below this range, because unobstructed winds across the open waters of a lake are normally faster than across land. The wind speed that triggers the advisory has changed over time. Until the late 1960s, the threshold was 32 to 38 miles per hour (or 28 to 33 knots). At some point, the lower limit was ...
Significant wave height H 1/3, or H s or H sig, as determined in the time domain, directly from the time series of the surface elevation, is defined as the average height of that one-third of the N measured waves having the greatest heights: [5] / = = where H m represents the individual wave heights, sorted into descending order of height as m increases from 1 to N.
