How White County floods

Flash flooding from summer thunderstorms dominates the historical flood profile of White County, Indiana, accounting for 19 out of 23 recorded flood events over the last 30 years alongside 4 general flood events.

Severe weather patterns drive these occurrences, as seen in June 2013 when training storms produced high precipitable water values and localized flash flooding, and in June 2015 when slow-moving thunderstorms caused additional flooding. Winter and spring events also occur, such as a February 2018 flood driven by a rapid snowpack melt combined with record-high February precipitable water levels and several rounds of rain.

National Flood Insurance Program records show that properties in high-risk Zone A have filed 165 claims with an average water depth of 11 inches and an average payout of $22,627. Additionally, properties in Zone X have experienced 30 claims with an average water depth of 8 inches and an average payout of $29,693, while Zone X-unshaded properties recorded 15 claims averaging 2 inches of water depth and $16,342 in payouts. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A, as well as those in Zone X where significant flood claims and water depths have also been recorded.

Where the flood claims came from

8% of White County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Flood · Feb 20, 2018. A slow release of a snow pack, containing one to over two inches of water, occurred in the days leading to the event which started the process of river rises in many areas. Low pressure tracked from northwest Iowa into northern Lower Michigan, which ushered in a rapid warmup and equally rapid release of any remaining water in the snow-pack. Several rounds of rain occurred between the 19th and 21st of February acro…

Flood · Jun 12, 2015. Numerous showers and thunderstorms developed ahead of a low pressure center which moved through the area. With moderate instability and shear, numerous severe storms developed with several reports of damaging winds. In addition, storm motion nearly parallel to the frontal boundary caused training storms and localized flooding in a few locations.

Flash Flood · Jun 1, 2013. Convection moved into the region during the evening hours of May 31st. Although this weakened, the remnants of it provided a west to east focus for continued development of showers and thunderstorms. Precipitable water values of around 2 inches were in place, with training of cells common into the overnight hours of June 1st. To further complicate matters, the comma head of a large bow echo propagated northeast ou…

Flash Flood · Jul 2, 2011. Two lifting mechanisms, a cold front and a lake breeze, interacted with an extremely unstable, but poorly sheared environment, to allow for thunderstorm development. Initially discrete cells posed a hail threat, but eventually congealed into several bowing segments.

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 White County

If a building in White 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.
