Flash flooding from heavy rainfall events dominates Greene County's flood character. Over the past 30 years, the NOAA Storm Events Database recorded 88 flood events and 26 flash flood events, resulting in 3 fatalities. Recent examples include flash flooding in southwestern Greene County in March 2024, following nearly stationary thunderstorms that dropped up to 3.75 inches of rain, and widespread flash flooding in April 2025 after 4 days of heavy rainfall that pushed main stem rivers to major flood stage.
While the National Flood Insurance Program (NFIP) data shows fewer claims in higher-risk zones, claims in "Unknown" flood zones have shown higher average payouts and water depths compared to Zone X. This suggests that properties not clearly mapped into standard flood zones may still experience significant flood damage. Homeowners and real estate agents should pay close attention to properties located near creeks and rivers, as well as those without a defined Base Flood Elevation (BFE), as these areas may be more susceptible to the types of flooding experienced in Greene County.

Flash Flood — Apr 4, 2025
The final round of rain in a stretch of 4 days brought rain amounts of 2-4.5 inches of rain to central Indiana in addition to the 3-5 inches that had fallen. This led to additional widespread flash flooding and exacerbated ongoing creek and river flooding to a point that many main stem rivers ended up reaching major flood stage.
Flash Flood — Mar 5, 2024
During the late afternoon into early evening hours of March 5th, slow moving to nearly stationary thunderstorms caused periods of heavy rain across south central Indiana with pockets of flash flooding in both Washington, Indiana and southwestern Greene County. Rain gauges reported up to 3.75 inches of rainfall near these areas of flash flooding.
Flash Flood — Feb 7, 2019
A low pressure system moved into the forecast area bringing plentiful moisture and produced thunderstorms and waves of moderate to heavy rain to central Indiana around February 7th. The storms produced a tornado in a strong shear and low instability environment. Over 4 inches of rain fell in a couple of days in some areas. The heavy rain produced flash flooding, and extensive flooding developed...
Flash Flood — Sep 8, 2018

Precipitable water, a measure of moisture content in the atmosphere, is normally around 1 inch for early September in Indiana. Precipitable water amounts approached 2 inches for parts of the area on September...
