FEMA’s digital flood map shows no high- or moderate-risk zones in Yoakum County. That can mean the area was never studied in detail or has no digital map, not that it can’t flood; the county floodplain administrator can say which.

Share of the whole county outline, rivers and lakes included; parts FEMA hasn’t mapped count as zero.

How Yoakum County floods

Flash flooding from severe summer thunderstorms and slow-moving weather systems dominates the flood risk in Yoakum County, accounting for 11 flash flood events alongside 4 general flood events over the last 30 years.

Recorded historical events illustrate these patterns. In May 2022, widespread severe thunderstorms developed near the Texas/New Mexico line, tracking eastward across the region. Previously, in July 2014, showers and thunderstorms regenerated across portions of Yoakum County following earlier heavy rainfall and high water that plagued area roadways.

National Flood Insurance Program records show that flood claims in the county are concentrated in specific areas, with Zone A accounting for 13 claims averaging $7,378 in payouts and an average recorded water depth of 2 inches. One claim was recorded in an unknown zone, averaging $6,233 and an average water depth of 1 inch. Property owners located within Zone A should pay the closest attention to local flood risks and insurance requirements.

In flood insurance claims here that reported a flood depth, the average was 2 inches.

From the storm reports

Flash Flood · May 28, 2023. Scattered supercell thunderstorms developed on the afternoon of the 28th and persisted through the evening producing several severe storms despite weak background forcing. Strong instability developed while the atmosphere became uncapped which allowed these supercell thunderstorms to develop. A slow moving storm near Vigo Park produced a brief tornado over an open field. More widespread thunderstorms evolved late…

Flood · May 10, 2022. Widespread severe thunderstorms developed on the afternoon of the tenth as a weak upper level disturbance ejected overhead northward out of Mexico. The initial activity rapidly developed near the dryline, which was located near the Texas/New Mexico line, late Tuesday afternoon. Aided by strong instability, several of the storms quickly became severe mostly producing severe thunderstorm winds. The thunderstorms gra…

Flood · Apr 13, 2015. Numerous slow moving showers and thunderstorms developed this morning north of an upper low located over the western Permian Basin. One particularly intense band of rainfall trained northwestward across western Terry and eastern Yoakum Counties late this morning for nearly three hours. Rainfall totals underneath this band measured as great as seven inches at the Tokio (Terry County) COOP gin. The NWS Lubbock regio…

Flood · Jul 2, 2014. An early morning upper level disturbance combined with moist upslope flow, aided by a nearby frontal boundary, to produce showers and thunderstorms. Portions of Parmer County in and around Bovina received between 4 to 6 inches of rainfall, with locally higher amounts estimated by radar. High water plagued area roadways causing multiple reports of traffic related issues. Showers and thunderstorms regenerated during…

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.

Flood insurance in Yoakum County

If a building in Yoakum 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.
