May 2019 was the second-wettest month in U.S. history.
Drenching rains and historic flooding last month contributed to a record-wet, 12-month period, from June 2018 through May 2019, according to the latest climate report from the National Oceanic and Atmospheric Administration, or NOAA.
For Ohio, it was the wettest year on record in the last 124 years. (Scroll down for a chart with historical perspective of Ohio’s rainfall totals.)
Soggy conditions from June 2018 through May 2019 led to the wettest 12-month period on record in the U.S., with 37.68 inches, 7.73 inch above average. The previous June-May record was 35.47 inches and occurred from June 1982-May 1983. The previous all-time 12-month record was 36.20 inches and occurred from May 2018-April 2019.
