Lake Wind Advisory:

Lake Wind Advisories are issued when sustained winds of 25 knots or greater are expected for several hours during the first 12 hours of the forecast. Typically wind forecasts are expressed in ranges. Thus for example a wind forecast of 15 to 25 knots, or 20 to 30 knots would both constitute advisory level conditions. Winds of this magnitude typically create choppy to rough water in exposed areas, leading to potentially hazardous conditions for those operating small craft.
