Canadian marine warning program: chapter 2

Freezing Spray Warnings

Freezing Spray Warnings are relevant to all marine interests and can be issued for all marine areas (coastal, inland and offshore) that have a regular or recreational marine forecast. Freezing Spray Warnings are issued when moderate or severe freezing spray is occurring or is forecast to occur. Moderate or severe freezing spray implies ice build-up at rates of 0.7 cm/hr or faster.
