How Quay County floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Quay County, NM, supported by 23 recorded flash flood events over the last 30 years. Storms moving across the eastern plains are driven by seasonal moisture and regional weather systems, as seen during widespread heavy rainfall events in October 2017, July 2021, and late May 2023.

National Flood Insurance Program records show claims filed across multiple zones, including 9 claims in Zone A with an average recorded water depth of 1 inch and an average payout of $5,512. Additionally, 2 claims were recorded in unshaded Zone X with an average recorded water depth of 3 inches and an average payout of $5,075.

Homeowners, real estate agents, and journalists should pay the most attention to properties located within Zone A, as well as properties situated in unshaded Zone X areas where localized water accumulation can occur during intense convective storms.

From the storm reports

Flash Flood · May 26, 2023. Several consecutive days of significant severe weather impacted eastern New Mexico from May 24-26, 2023. Showers and thunderstorms developed along the dryline and east slopes of the Sangre de Cristo Mountains on May 23rd. Storms tracked east and southeast across the eastern plains of New Mexico. Extensive severe weather was reported when these storms encountered greater moisture and lift closer to the Texas border…

Flash Flood · Jul 17, 2021. Abundant moisture remained over New Mexico on July 17, 2021, as evident by precipitable water values in the 90th percentile. Despite an area of high pressure over the state, it was a very active day for northern and central New Mexico with widespread showers and thunderstorms. The most intense convection of the day came late in the evening as a weak disturbance rounded the high pressure and interacted with the ric…

Flash Flood · Oct 5, 2017. An upper level low pressure system developed over the Great Basin during the first week of October and delivered another round of widespread showers and thunderstorms to New Mexico. This weather pattern was similar to the pattern that impacted the area with severe storms and flooding at the end of September. Saturated soils over much of central and eastern New Mexico from late September exacerbated the flash flood…

Flood insurance in Quay County

If a building in Quay 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.
