Description:

The Scaled Predictive Ice Storm Aftermath Index (SPIA Index) utilizes gridded forecasts routinely prepared by NWS WFOs as a part of the National Digital Forecast Database.  Forecast wind and ice accumulation grids are parsed to determine where specific overlapping criteria are met.  The effects of the wind and ice accumulation are scaled from zero to five, with each element of the scale describing expected impacts to exposed electric utility systems.  During an ice storm, forecast grids are combined with observed wind and ice accumulations grids to fully quantify the impacts.
