A Terrifying, Deadly Storm Struck Idaho In 1949 And No One Saw It Coming
Idaho, with its tumultuous geology, diverse weather regions, and abundant scenic beauty is no stranger to the darker forces of nature and nor the impacts of its human residents. In 1910, the Big Burn ravaged Northern Idaho, the product of a grueling summer storm. In 1976, the Teton Dam collapsed, devastating the eastern part of the state. But Idaho’s storm of the century created a winter disaster that was just as unexpected and deadly, the most intense seen since the 1800s, and far more brutal than any other weather-related event seen since. In 1949–a mere two generations ago–an unprecedented cold snap tore through southern Idaho, virtually isolating the southern half of the state for weeks and shutting down the economy for a month. But low temperatures are only part of this chilling story.

Dad remembered the winter of 49 here in SW Idaho, and talked about it numerous times.
