FEMA’s digital flood map shows no high- or moderate-risk zones in Garza 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.

How Garza County floods

Flash flooding from severe thunderstorms and heavy rainfall dominates the flood risk profile in Garza County. Over the last 30 years, the NOAA Storm Events Database recorded 21 flash flood events, alongside 7 general flood events and 1 tropical depression.

Recent occurrences illustrate these patterns. In August 2022, a stationary upper-level storm system brought near-record moisture levels to West Texas, producing torrential rain that saturated soils and inundated area roadways, stopping traffic. In April 2025, a combination of a cold front, an upper-level storm system, and an unstable atmosphere fueled severe thunderstorms that produced heavy rainfall and flash flooding across the region.

National Flood Insurance Program records show limited claims activity, with a single claim filed in Zone A resulting in an average payout of $11,853 and an average recorded water depth of 0 inches. Property owners located within Zone A should pay the closest attention to flood risk and mitigation options.

From the storm reports

Flash Flood · Apr 29, 2025. A cold front moved into the South Plains region on the afternoon of the 29th which fueled severe thunderstorm development along with flash flooding produced by heavy rainfall. A large upper level storm system was moving southeastward into western New Mexico with a weak short wave trough moving over West Texas. Lift from these features combined with the southward moving cold front to initiate thunderstorms across t…

Flash Flood · Apr 24, 2025. Another day of widespread severe thunderstorms occurred on the afternoon and evening hours of the 24th. Persistent but weak southwesterly flow aloft increased on the 24th which allowed supercell thunderstorms to produce giant hail. Increased low level southeasterly winds also allowed these thunderstorms to produce numerous tornadoes. Thunderstorms initially developed late in the afternoon along a dryline along the…

Flash Flood · Jun 1, 2023. Rich moisture, a weak upper level disturbance, and several low-level boundaries worked in concert to bring torrential rainfall to portions of the south-central and southeastern South Plains on the first. One of the primary factors, in addition to the plentiful moisture, was a low-level boundary, originating from thunderstorm activity that affected the Texas Panhandle the previous evening into the overnight hours,…

Flash Flood · Aug 31, 2022. An upper level storm system became nearly stationary, centered close to El Paso, which allowed extremely moist air to continue to be pumped up into West Texas on the 31st. The near record moisture levels, along with the nearby upper level low, and weak daytime heating, initiated a round of westward-moving showers and thunderstorms that dumped torrential rain in spots adding to the already saturated soils. A number…

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 Garza County

If a building in Garza 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.
