Strong Winds have sustained wind speeds in the range of 20 to 33 knots (37 to 61 km/h). Water surface conditions during a strong winds advisory are very rough with waves 3 to 6 m in height. Environment Canada issues a Small Craft Warning when winds reach such levels. It is not safe to operate a pleasure craft under these conditions.

Operators of vessels caught in a strong winds advisory or small craft warning should take immediate action to ensure their safety. Turn on all navigation lights and attempt to cross waves at a 45° angle until sheltered waters are found. Reduce speed and proceed with caution, keeping a look-out for approaching boats and floating debris. If wind and wave conditions make it difficult to proceed, attempt to anchor your vessel until the storm subsides. Ensure all passengers are wearing approved flotation devices and keep passengers low in the boat and near the centerline.
