How Cuming County floods

Flash flooding from summer thunderstorms and severe weather dominates Cuming County, with NOAA records over the last 30 years documenting 23 flash flood events and 15 general flood events.

Historic flooding occurred in March 2019 when a 971mb bomb cyclone moved out of the central Rockies, combining rapid snowmelt from 4 to 15 inches of snow cover, frozen ground with frost depths of 15 to 23 inches, and 1 to 2.5 inches of rain over a 48-hour period. Later that year in September 2019, strong nighttime thunderstorms produced heavy rainfall between 3.75 and 4.3 inches across areas including Lyons, Pilger, and Pender.

NFIP claim history shows that properties in Zone A experienced the highest impact with 32 claims, an average payout of $23,683, and an average recorded water depth of 2 inches. Additional claims occurred in Zone X (4 claims, average payout of $685, average depth of 1 inch), Zone X shaded (4 claims, average payout of $1,895, average depth of 0 inches), Zone X unshaded (2 claims, average payout of $21,770, average depth of 1 inch), and Zone unknown (1 claim, average payout of $0, average depth of 0 inches). Homeowners and real estate agents with properties in Zone A should pay the closest attention to these flood risks.

Flood · Mar 14, 2019. A 971mb bomb cyclone moved out of the central Rockies on Wednesday, March 13, 2019 and helped to create widespread, moderate to major, and in many cases historic, flooding across eastern Nebraska and western Iowa. From 4 to 15 inches of snow cover remained across the mid Missouri River valley, and the ground was frozen with existing frost depths of 15 to 23 inches.

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.

Cross-section of a river floodplainDiagram: a river valley.

Flood insurance in Cuming County

If a building in Cuming 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.
