This May was the wettest on record for the contiguous United States, according to federal weather data.
The National Oceanic and Atmospheric Administration reports 4.36 inches of rain fell on the contiguous U.S. this May, 1.45 inches above average and the most rain the administration has recorded for the month of May in 121 years.
The total precipitation that fell in the spring was 9.33 inches, making it the 11th wettest spring on record for the contiguous U.S.
Severe weather events and heavy rainfall across the U.S. have contributed to the uptick in precipitation. Fifteen states had totals well above average, including Oklahoma, Texas, and Colorado which each suffered severe flooding. However, seven states along the East Coast had lower than average levels of precipitation.
About 24.6% of the contiguous U.S. was in drought according to a June Drought Monitor report, an improvement across the board though many states in the West, Northwest, Southeast and Northeast have seen drought conditions worsen.
So far, 2015 has brought a number of record-setting months weather-wise. January through March 2015 was the warmest first three months of the year on record across the globe. In the contiguous U.S., this January to May has been the 17th warmest in the 121 years that the NOAA has tracked temperatures.
