Freezing rain advisory
A freezing rain advisory was an advisory issued by the National Weather Service in the United States when freezing rain or freezing drizzle was expected to cause significant inconveniences, but did not meet warning criteria (typically greater than 1⁄4 inch or 6.4 millimetres of ice accumulation).[1]
On October 2, 2017, issuance of the freezing rain advisory was discontinued. A winter weather advisory is now issued when the above criteria are forecast to be met.[2] However, ice storm warnings continue to be issued.
