Frequently asked questions

What is the highest cold wave risk county in Virginia?

Smyth County, VA has the highest cold wave risk in Virginia, with a FEMA National Risk Index score of 91.2 out of 100 (rated "Relatively High").

What causes cold wave risk in Virginia?

Cold wave risk captures expected losses from extended periods of extreme cold, including wind chill. The northern Plains, Great Lakes, and interior New England see the most severe and frequent cold events. Cold extremes cause significant excess mortality, especially among unhoused populations, the elderly, and those with inadequate heating or insulation. Cold and wind chill events are reported at forecast-zone level in NOAA Storm Events and are not included in county-level counts.
