Flash flooding from summer thunderstorms dominates the flood risk profile in Jasper County, Illinois, accounting for 40 of the 49 recorded flood events over the last 30 years, alongside 9 standard flood events.
Recent history illustrates these heavy rainfall threats. In August 2022, continuous back-building storm cells dropped over 8 inches of rainfall across the county. Similarly, the remnants of Tropical Storm Gordon brought heavy rainfall ranging from 5 to 10 inches in September 2018, and saturated soils exacerbated localized flash flooding from thunderstorms in June 2018. National Flood Insurance Program records indicate claims spanning multiple zones, including Zone X_UNSHADED with 5 claims averaging a $28,151 payout and 6 inches of recorded water depth; Zone A with 4 claims averaging a $15,823 payout and 4 inches of recorded water depth; and Zone X with 1 claim averaging an $878 payout and 23 inches of recorded water depth.
Property owners in both mapped Special Flood Hazard Areas like Zone A and unshaded or standard Zone X areas should pay close attention to this risk, as significant payouts and water depths have been recorded across multiple zones during intense local rainfall events.

Flash Flood · Aug 1, 2022. An outflow boundary from convection earlier in the day served as the primary focusing mechanism for numerous storm clusters along and south of I-70 from the late afternoon of August 1st into the pre-dawn hours of August 2nd. Some of the storms dropped very large hail up to 2 inches in diameter. In addition, continuous back-building cells produced a swath of heavy rainfall in excess of 8 inches from eastern Effi…
Flash Flood · Jun 11, 2018. A series of weak impulses interacted with a stationary frontal boundary extending from northeast Missouri to southwest Indiana to produce several rounds of thunderstorms across south-central Illinois from the evening of June 11th into the morning of June 12th. The strongest cells produced damaging wind gusts of around 60mph and hail as large as golf balls during the evening of June 11th. In addition, excessive r…
Flash Flood · Sep 8, 2018. Heavy rain impacted central and southeast Illinois as the remnants of Tropical Storm Gordon tracked from Arkansas during the afternoon of September 7th to southern Ohio by the afternoon of September 9th. The rainfall was further enhanced by a weak cold front dropping southward out of the Upper Midwest. Rainfall was heaviest south of I-70 in closer proximity to the track of the storm, with amounts ranging from 5…
Flood · Apr 29, 2017. Heavy rainfall impacted central and southeast Illinois from April 29th into April 30th...creating flash flooding, which led to widespread areal flooding. Periods of thunderstorms with very high rainfall rates dropped 2.00 to 6.50 inches of rain across much of central and southeast Illinois from April 29th into early on May 1st. This rainfall, occurring on top of already saturated soils, created flash flooding in a…

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 Jasper 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.
