The first occurred in January across the South, Southeast, and Great Lakes states causing tornadoes, flooding, and coastal erosion. More than 80 tornadoes were reported in addition to widespread flooding across the Southeast. The second event was in March when overnight tornadoes ripped through the Nashville, Tennessee area and extending storm damage across the surrounding states. More than 40 buildings were destroyed and over 24 fatalities were reported. The United States has now sustained 265 weather and climate disasters since 1980 where damages and costs reached or exceeded $1 billion. This brings the grand total of damage costs to over $1.775 trillion since 1980.
