Flash Flood · May 30, 2024. Multiple rounds of thunderstorms brings isolated, but significant, heavy rainfall to portions of Howard County from May 30th into the 31st. The initial bout of strong thunderstorms and heavy rainfall developed during the early morning hours of May 30th. This activity was the result of a mesoscale convective vortex (MCV) that emanated from convection over the High Plains the previous evening. Another round of stro…
Flash Flood · Jun 21, 2024. Although it impacted only a handful of west central and especially northern counties of South Central Nebraska, a persistent narrow band of heavy rain on the evening of Friday the 21st into the pre-dawn of Saturday the 22nd caused what was likely the overall most impactful flooding event of 2024 within the 24-county area. Over the course of 10 hours between 5 p.m. and 3 a.m. CDT, numerous and mostly sub-severe thu…
Flood · Aug 23, 2019. As severe storm/flooding events go, some are definitely better-anticipated than others (forecast-wise).

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 Sherman 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.
