Sources of Data on Freezing Rain and Resulting Damages

Abstract

Freezing rain produces major damages each year in the United States, and various affected groups continue to seek data on the incidence and losses produced by freezing rain. The various kinds of data available about freezing rain and related damages have been identified and assessed as part of a project to develop long-term databases. Data include long-term records of the occurrences of freezing rain, 50-yr records of insured property losses, and measures and estimates of ice loading on wires and structures. Many years of interactions with affected and interested groups and individuals, such as the insurance industry and design engineers, led to the preparation of this summary that describes the various sources of data on freezing-rain and ice-storm damages. The benefits and limitations of each form of data are presented to help to guide potential data users.
