What causes cold wave risk in Texas?

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 and wind chill events are reported at forecast-zone level in NOAA Storm Events and are not included in county-level counts.
