Abstract : A climatology of glaze storms occurring in the U.S. from 1919-20 through 1968-69 was compiled. A subjective analysis of these storms was used to develop probability estimates of ice accretion for seven regions in the U.S. east of the Rocky Mountains. Estimates of combined ice and wind loads are also present. The greatest probability of severe ice storms exists from the central and northern plains through the upper midwest eastward to New England. The single point probability of at least one occurrence of an ice storm + or > 2.5 cm in one year in the northeastern U.S. is 0.0002. The single point probability of an ice storm = or > 5.0 in this same area is 0.00018. For the southeastern U.S. the probability of such occurrences in one year are 0.0004 and near zero, respectively.
