Great Lakes Storm Winds, Waves

September 28, 2009; 9:09 AM ET

UPDATE 9/29: Looks like #45012 had waves over 10 feet last night. I saved off some "greatest hits" graphs here.

UPDATE 7 PM: As Eric suggests in the Comments below, check out this webcam to see the waves roll in on Lake Michigan. A seiche, similar to a hurricane's storm surge, is currently ongoing on Lake Erie. The water level at Buffalo, NY is up over 5 feet while at the other end of the Lake Toledo, OH is down 5 feet! Buoy #45005 north of Cleveland is now clocking winds of 43 knots and waves to 8.9 feet. At #45012 on Lake Ontario, 43 knots and waves to 7.9 feet.

ORIGINAL POST: Here's a look at the Great Lakes storm this morning via RadarPlus:

as of 10 AM Eastern, the highest readings were 37 knot wind gusts and 7 foot waves at Buoy #45005 north of Cleveland.

Our news story says that conditions will continue to get worse today and tonight:

A storm over the upper Great Lakes will continue to lash portions of the Upper Midwest and Great Lakes today through tonight with high winds and rain. Winds will cause chilly RealFeel® temperatures and damage due to toppled trees and power lines. Thousands across the region already had power cut Sunday. Other areas could experience power outages today. Winds will also whip the waters of the Great Lakes into a fury. Waves will be as high as 15 feet on Lake Michigan and over 20 feet on Lake Superior. Conditions will be dangerous for recreational boaters and commercial shipping.

You can keep an eye on the winds & waves from the buoys on the lake at NDBC; in case of a seiche (see yesterday's blog entry) water level information can be obtained here.
