How Warrick County floods

Standard river flooding dominates the flood character of Warrick County, backed by a significant secondary threat of flash flooding from severe storms over the last 30 years. NOAA records document multiple recent high-water events, including flash flooding that closed roads from the Angel Mounds area eastward through Newburgh on February 15, 2025, and training storm activity producing torrential rainfall rates in the Evansville and Newburgh area on July 18, 2025.

Federal insurance data shows that flood damage is not restricted to high-risk areas. Properties in Zone A account for the highest claim volume with 40 filings averaging $10,863 and an average recorded water depth of 13 inches. However, properties in Zone X also face meaningful risk, recording 20 claims with an average payout of $16,718 and an average recorded water depth of 20 inches. Unshaded Zone X properties filed 9 claims averaging $13,562 with an average water depth of 6 inches, while 6 claims in unknown zones averaged $2,043 with a 2-inch average depth, and 2 claims in shaded Zone X averaged $1,118 with 0 inches of recorded water depth.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within designated Zone A riverine floodplains, as well as moderate-to-low risk Zone X properties where lower-frequency storms have historically produced severe, costly water accumulation inside structures.

Where the flood claims came from

22% of Warrick County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Flash Flood · Jul 19, 2025. As high pressure slowly crept northward towards the Quad State region, ridging remained over the middle Mississippi River Valley. A slow-moving MCS moved through the northeastern half of the Quad State midday to near sunset. CAPE rose to 1000-2000J/kg in Southwest Indiana with effective bulk shear around 30kts. Extremely high moisture content with precipitable water values of 2.25in resulted in torrential rainfall…

Flood · Jul 18, 2025. A surface boundary was positioned west to east across the Quad State during the early afternoon with convective activity increasing with daytime heating. Scattered convection primarily occurred south of the boundary mid to late afternoon. MLCAPE reached 2000-3000J/kg but effective bulk shear was very limited. Precipitable water values over 2 allowed for torrential rainfall rates. Training storm activity occurred n…

Flood · Jul 15, 2025. A morning frontal boundary on the northern edge of the Quad State lifted a little northward during the day on the 15th. A 40-50kt jet out of the WSW continued into the Quad State, bringing enough Gulf moisture to keep PWATs over 2 inches. MLCAPE values reached 2000-2500J/kg, while effective bulk shear remained limited. In Southwest Indiana, scattered showers and thunderstorms occurred through the day. A funnel clo…

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.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Warrick County

If a building in Warrick 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.
