Shaded areas are FEMA’s mapped flood hazard zones in and around Greene County, Pennsylvania. Zoomed out they are simplified; at street level the map switches to FEMA’s exact layer. Tap anywhere to check that spot, or search an address above.
Flash flooding from summer thunderstorms and severe weather events dominates the flood profile of Greene County, Pennsylvania, accounting for 55 recorded events alongside 38 general flood events over the last 30 years. NOAA storm narratives illustrate these patterns, noting flash flooding driven by slow-moving cloud-bearing layer winds and high precipitable water values in July 2025, as well as widespread flooding caused by multiple rounds of showers and thunderstorms dropping four to five and a half inches of rain across the region in April 2
Summary written from NOAA storm reports and NFIP claims for this county. Not a prediction.
17% of Greene County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.
178 NFIP claims with a recorded rated flood zone, 1978 to date. The zone is the one FEMA used to rate that policy, which may not match today’s map. Source: OpenFEMA NFIP claims.
In flood insurance claims here that reported a flood depth, the average was 7 inches.
Drawn to scale against an 80-inch door. Even a few inches soaks flooring, the bottom of the drywall and anything plugged in near the floor.
Average of the depths reported on claims (zero and implausible values left out); FEMA’s record doesn’t say exactly where each depth was measured. Source: OpenFEMA NFIP claims.
The worst year was 2004, with 51 claims and $1.2M paid, the year of Severe Storms and Flooding Associated With Tropical Depression Frances and Tropical Depression Ivan.

Flash Flood · Jul 25, 2025. Overnight sub-severe convection and remnant boundaries from said convection acted as initiating mechanisms for development later in the morning and afternoon hours. A moist and unstable environment with up to 2500 J/kg MLCAPE and 30 knots of effective shear supported storm organization and maintenance. Favorable DCAPE between 800-1000 J/kg resulted in some instances of damaging wind. In addition, slow cloud bearin…

Flood · Apr 3, 2024. Several rounds of showers and thunderstorms prompted a widespread flash flood problems across the Ohio River Valley on April 2nd to April 3rd. The synoptic pattern across the CONUS was a slow moving and deep elongated trough over the Great Plains phasing with a ejecting trough over the Midwest that created an area of converging moisture over eastern Ohio and western Pennsylvania. Overall, over a span of 4 days, fo…

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Greene County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
