How Greene County floods

Flash flooding dominates the flood character of Greene County, accounting for 40 events out of 48 total recorded flood events over the last 30 years, alongside 7 general floods and 1 tropical storm. NOAA storm records illustrate this hazard, noting heavy rainfall and flash flooding from a low-pressure system and cold front on January 30, 2025, as well as heavy rain and training storms associated with a frontal system on April 5, 2025.

National Flood Insurance Program records show claims across multiple zones, with the highest volume concentrated in Zone A at 188 claims with an average payout of $5,211 and an average recorded water depth of 3 inches. Zone X accounts for 26 claims with an average payout of $15,567 and an average recorded water depth of 5 inches. Additionally, Zone UNKNOWN recorded 15 claims with an average payout of $5,751 and an average water depth of 1 inch, while Zone X_UNSHADED recorded 6 claims with an average payout of $1,253 and an average water depth of 1 inch.

Property owners in Zone A and Zone X should pay the most attention to flood risk, given the high concentration of historical claims and significant average water depths during flood events.

Where the flood claims came from

3% of Greene County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Flash Flood · Jan 30, 2025. A low-pressure system and associated cold front resulted in heavy rainfall and flash flooding across parts of east Arkansas. Ample moisture provided the fuel for training storms which produced two to four inches of rain during the early afternoon along and west of the Mississippi River. The heavy rainfall axis then shifted east over a less saturated surface and the flooding threat diminished.

Flash Flood · Apr 5, 2025. The front eventually sagged south back into the Mid-South during the early morning hours of April 5th. Strong low-level moisture transport into the frontal zone resulted in heavy rain and training storms across northern sections of the Mid-South, mainly north of I-40. A bow echo developed along and just south of the slowly advancing front. This feature crossed the entire forecast area producing 13 tornadoes, inclu…

Flash Flood · Jan 2, 2023. A warm front lifted northward off the Gulf Coast, causing rapid moisture transport to the Mid-South. In addition, an upper-level trough and associated cold front approached the area. This led to showers in the afternoon and then severe thunderstorms that continued through the overnight hours. Damaging wind, hail, tornadoes, and flash flooding were the result.

Flash Flood · Jun 7, 2022. Remnant outflow boundaries from the previous day's storms resulted in scattered convective development. A moist and unstable atmosphere combined with the previous day's rainfall created a perfect opportunity for showers and strong thunderstorms with hail, damaging wind, and flash flooding.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Greene County

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.
