How Elk County floods

Flash flooding from severe weather events dominates the flood risk profile in Elk County, Kansas, accounting for nearly two-thirds of all recorded flood incidents over the past 30 years with 24 flash flood events compared to 13 general flood events.

Recent history illustrates these recurring hazards. On May 15, 2020, severe storms produced widespread flooding and flash flooding alongside damaging winds that resulted in a fatal roadway collision. More recently, volatile weather on April 27, 2024, brought numerous rotating storms and tornadoes to southeast Kansas, while subsequent storms on May 6, 2024, and May 16, 2024, brought heavy rain and wind threats to the region.

Federal insurance claims data shows limited historical payouts in mapped high-risk areas, featuring a single claim in Zone A with an average payout of $25,000 and an average recorded water depth of 0 inches. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within designated Zone A flood zones, where rising waters from intense convective storms pose the primary threat.

From the storm reports

Flash Flood · Apr 27, 2024. On Saturday April 27th, there was volatile severe weather across Kansas and Oklahoma. An abundance of moisture and increasing shear through the day resulted in numerous rotating storms which produced several tornadoes across the Flint Hills into southeast Kansas. The strongest tornado was an EF-2 which occurred in Cowley County which did damage to a few outbuildings. Luckily there were no injuries or fatalities re…

Flood · May 16, 2024. A cluster of supercells developed across portions of Harper and Cowley counties during the afternoon of May 15th and quickly began producing large hail and damaging winds. This cluster of storms expanded north and eastward continuing to produce quarter to two inch sized hail across south central and southeast Kansas. Meanwhile, a second cluster of storms developed across northwest Oklahoma and progressed into sout…

Flood · May 6, 2024. A dryline and Pacific cold front moved into the region on Monday May 6th, and with abundant moisture and instability already in place, storms erupted by the early afternoon hours across west-central Kansas. As storms tracked across central Kansas they produced hail up to slightly larger than baseballs! Storms became more numerous over southeast Kansas after sunset with wind and heavy rain becoming the main threats…

Flash Flood · May 15, 2020. Severe storms dropped lots of hail, produced sporadic wind damage, and also caused widespread flooding and areas of flash flooding on May 15th, 2020. Hail sized remained below 1.5 inches and the winds were between 60 and 70 mph. Unfortunately, a tree was blown across a roadway and an individual did not see the tree and crashed into it and lost his life.

Flood insurance in Elk County

If a building in Elk 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.
