From May to August, the U.S. experienced four new billion-dollar weather and climate disasters

  • Tornadoes in the Plains and severe weather in the Central U.S. (May 8-11) resulted in two deaths and $1.6 billion in damages;
  • Historic flooding in West Virginia and tornadoes in the Ohio Valley (June 22-24) caused 23 deaths and $1 billion in damages;
  • Severe weather in the Rockies and the Northeast (July 28-30) caused $1.1 billion in damages but no fatalities; and
  • Massive flooding in Louisiana (August 12-15) resulted in 13 deaths and $10 billion in damages.

These four billion-dollar disasters, when added to eight earlier in the year, raised the tally to 12 in 2016 so far, which have claimed a total of 68 lives and caused $26.9 billion in damages. This is the second highest number of disasters; it also doubles the previous record for the number of inland flooding events in one year.

Since 1980, the U.S. has experienced 200 weather and climate disasters, exceeding $1.1 trillion in overall damages, according to scientists from NOAA’s National Centers for Environmental Information.
