The 1899 New Richmond Tornado was an estimated F5 tornado which formed on the early evening of Monday, June 12, 1899 and tore a 45-mile long path of destruction through St. Croix, Polk and Barron counties in west-central Wisconsin, leaving 117 people dead, twice as many injured and hundreds homeless. The worst devastation wrought by the tornado was at the city of New Richmond, Wisconsin, which took a direct hit from the storm. Over half the town was left in ruins by the tornado, which also caused lesser damage to several other communities in the area. More than $300,000 (USD) ($9,332,000 in today's dollars) in damage was reported. Today, it ranks as the ninth deadliest tornado in United States history, as well as the deadliest ever recorded in Wisconsin.
