Gale Warning
Statement as of 10:05 PM CDT on April 16, 2014

...Gale Warning remains in effect until 4 am CDT Thursday...

* winds...east to northeast 20 to 30 knots with gale force gusts to 45 knots.

* Waves...9 to 11 feet in ice free areas for the late evening and overnight. The winds could begin to break up the ice cover and generate waves where there is current ice cover.

Precautionary/preparedness actions...

A Gale Warning means winds of 34 to 47 knots are imminent or occurring. Operating a vessel in gale conditions requires experience and properly equipped vessels. It is highly recommended that mariners without the proper experience seek safe Harbor prior to the onset of gale conditions.

Winds and waves will also interact with large amounts of Winter Lake ice to pile up ice on any shorelines...harbors and Harbor approaches that are exposed to the northeast. In addition...lake ice embedded within the waves could result in very dangerous conditions for any vessels on Western Lake Superior.
