This paper describes the development of an ice storm data base and reg
ional ice severity maps for the US using information from Storm Data,
a National Climatic Data Center (NCDC) publication. This resource will
provide convenient access to ice storm information for electric utili
ty companies. Using this information, an engineer will be able to iden
tify important characteristics of ice storms for a specific area when
evaluating or designing a power line. Additionally, when developing lo
cal design ice load maps, the importance of correlating predicted icin
g events with historical ice storms makes this information even more v
aluable for utilities. (C) 1998 Elsevier Science B.V.
