Conditions are favourable for the development of wind gusts between 45 to 55 knots in marine regions in southwestern Hudson Bay early in the morning of Sunday October 25th. Potential for significant wave heights accompanies these winds, so mariners are advised to exercise caution, especially smaller vessels. The winds are expected to lessen in severity again over the course of the afternoon. This watch may be expanded eastward as the event draws nearer.
