Winter Ice Storm Damage Predictions – Icestorm Forecast

DCP_3700The weather’s preventing me from doing any metal detecting, so I’ve been adding a bit of interesting meteorological tidbits to this site so I can easily check things.

I’ve been learning about the Sperry-Piltz Ice Accumulation Index.  It’s a tool that predicts power outages by combining ice amounts and wind, both factors in damage/inconvenience (yes, that is a photo of my house in 2003.)    The maps below should stay updated as the day goes on, but you should REFRESH the page occasionally.  (And while you’re here, feel free to subscribe to my metal detecting site – if this weather breaks there will be some great stuff on it.)

Winter Storm – Ice Storm Forecast – Ice Damage Prediction for Wisconsin, Illinois, Michigan, Indiana, Kentucky, Virginia, Ohio, West Virginia, Maryland, New Jersey, Pennsylvania, New York, Rhode Island, Connecticut, Massachusetts, Vermont, New Hampshire, Maine, Washington, D.C. and Delaware.

I am not a meteorologist, this data is assembled here for your convenience – always use weather prediction authorities in your area when planning for a severe weather event.

About the maps above

The Sperry–Piltz Ice Accumulation Index, or SPIA Index, is a forward-looking, ice accumulation and ice damage prediction index that uses an algorithm of researched parameters that, when combined with National Weather Service forecast data, predicts the projected footprint, total ice accumulation, and resulting potential damage from approaching ice storms. It is a tool to be used for risk management and/or winter weather preparedness. Maximum forecast period is for 54 hours. Forecasted images only. Does not include observed ice.  (For more, see via

I would have just linked everyone to the page but it does not present the key to the index and maps on the same page (strangely.)    So this page does that for lay observers.
