Wettest counties in America
Rain, sleet, snow, hail, wintery mix. Precipitation takes on many forms and the degree to which climate change affects precipitation levels comes down to something most everyone learns about in school: Earth's water cycle. A system in endless motion, the water cycle traces the process through which water exists in its three primary phases—liquid, solid, and gas—as it moves perpetually between the earth and its atmosphere.
For a recent example of a heavy precipitous event, one need look no further than Hurricane Helene, which brought devastating floods to the Southeast in September 2024. More than 200 have been confirmed dead as of October, while countless structures and roads—including Interstate 40—have collapsed as a result of the storm's heavy rainfall.
Increasingly, such is the fate of areas lacking the infrastructure to withstand the growing prevalence of extreme, single-day precipitation events. June 2024 data from the Environmental Protection Agency shows a marked increase in these occurrences since the 1980s, likely due to climate change. The percentage of land area that sees higher than normal annual rainfall has also increased. Meanwhile, regions such as Oklahoma, Kansas, and Nebraska, as well as parts of Texas, experience the opposite extreme: drought, also largely a product of climate change.
The continental U.S. received an average of about 30 inches of precipitation between March 2022 and February 2023. Traditionally "wet" regions, such as Washington state and Alaska in the northwest and Georgia and Mississippi in the southeast, continue to have some of the rainiest counties in the United States. Other regions such as Oklahoma, Kansas, and Nebraska, as well as pockets of the South and California, experience the opposite extreme: drought, also largely a product of climate change.
Stacker cited data from the National Centers for Environmental Information to identify the 50 counties in the U.S. that receive the most precipitation through rain, sleet, or snow. Counties are ranked by five-year precipitation averages in inches as of February 2023, with rainfall over the past year serving as a tiebreaker. Supplementary data on how last year's precipitation compares to the 100-year average for the area is also included.
