Local Hazard History
Minneapolis is built for winter and still gets caught. The benchmark storm is the Halloween Blizzard of 1991, which dropped 28.4 inches on Minneapolis–St. Paul between October 31 and November 3 — still the largest snowstorm ever recorded in the Twin Cities. Cold is the more reliable threat. During the polar vortex of late January 2019, the temperature at MSP fell to −28°F on January 30, the coldest reading in the Twin Cities since 1996, with a wind chill near −55°F and twelve straight hours at or below −50°F; schools, businesses, and government offices closed for three days and the Postal Service suspended mail delivery. Snow load is its own hazard: 17.1 inches fell at MSP during the December 10–12, 2010 storm, and the weight collapsed the Metrodome's inflatable roof early on December 12. Minneapolis is also tornado country. On May 22, 2011, an EF1 tornado cut across North Minneapolis, killing one man, injuring 48, and damaging or destroying roughly 3,700 structures along a path that ran from St. Louis Park through Fridley and Blaine.
