How Jennings County floods

Over the last 30 years, Jennings County has experienced a flood risk profile dominated by standard river and stream flooding alongside significant flash flood events, with NOAA records showing 26 flood events and 15 flash flood events.

Heavy rainfall and slow-moving weather systems frequently trigger these hazards across the area. For example, a stationary boundary produced heavy rainfall that led to flash flooding across a portion of Jennings County on June 12, 2018. Later, a heavy rain event from January 9 through January 11, 2020, brought 3 to 5 inches of rain to the area, resulting in flooding.

National Flood Insurance Program records show claims filed across multiple zones, including Zone A, which recorded 6 claims with an average payout of $14,499 and an average recorded water depth of 13 inches. Additional claims occurred in Zone UNKNOWN, Zone X, and Zone X_UNSHADED, with average payouts ranging from $6,270 to $15,372 and average recorded water depths between 0 and 1 inches. Homeowners and real estate agents in Zone A—where deeper standing water has been documented during claims—along with properties situated near waterways and unmapped areas, should pay the closest attention to local flood risks.

From the storm reports

Flash Flood · May 8, 2024. Warm and humid conditions, including unseasonable dewpoints as high as 71 degrees at the Vincennes airport, were present across central Indiana ahead of an approaching cold front. Very heavy rain from an isolated, early evening thunderstorm drifting over portions of Jennings County eventually caused localized flash flooding west of Lovett. Later in the evening a broad area of convection arriving from Illinois in…

Flood · Jan 11, 2020. A period of heavy rain occurred from January 9th through the 11th that brought 3 to 5 inches of rain to the area. During the period of heavy rain a few thunderstorms brought gusty winds.

Flash Flood · Jun 12, 2018. A stationary boundary lingered over southern portions of central Indiana from late on the 11th to late on the 12th of June. This was the focus for a series of shower and thunderstorm complexes that produced copious amounts of rain over portions of Knox County, leading to flash flooding. Heavy rainfall also produced flash flooding across a portion of Jennings County as well.

Flood · Jun 15, 2017. The heaviest rains of more than 4 inches, fell on the 13th and 14th of June in portions of northwest and southeast Indiana. Precipitation covered nearly the entire state on the 14th.

Flood insurance in Jennings County

If a building in Jennings 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.
