How Kerr County floods

Flash flooding from intense summer thunderstorms dominates the flood profile of Kerr County, Texas. Over the last 30 years, the NOAA Storm Events Database records 99 flash flood events resulting in 119 deaths, compared to 11 standard flood events resulting in 1 death.

This hazard is driven by weather patterns such as the July 2005 event, when remnants of Tropical Storm Barry brought near-record moisture levels into Texas. A low-level jet streak subsequently produced training thunderstorms over the Texas Hill Country during the overnight hours of July 3-4, 2005.

Homeowners, real estate agents, and journalists should pay the most attention to properties in high-risk areas. NFIP claims data shows the highest volume of claims occurs in Zone A with 239 claims averaging $93,528 and an average recorded water depth of 12 inches. However, properties in Zone X also face significant risk, accounting for 87 claims with an average payout of $61,649 and a higher average recorded water depth of 35 inches. Zone X_UNSHADED recorded 23 claims averaging $9,878 with an average water depth of 2 inches, Zone UNKNOWN recorded 15 claims averaging $4,542 with an average water depth of 3 inches, and Zone X_SHADED recorded 9 claims averaging $10,526 with an average water depth of 7 inches.

Where the flood claims came from

12% of Kerr County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

In flood insurance claims here that reported a flood depth, the average was 16 inches.

From the storm reports

Flood · Jul 14, 2025. A mesoscale convective vortex developed along the Rio Grande and moved northeastward across South-Central Texas. Thunderstorms from this complex produced locally heavy rain that led to flash flooding.

Flash Flood · Jul 13, 2025. Thunderstorms formed along an outflow boundary in a moist airmass over Central Texas and moved into the Hill Country and Edwards Plateau. Some of these storms produced locally heavy rain that led to flash flooding.

Flash Flood · Jul 4, 2025. Tropical Storm Barry moved into and dissipated over eastern Mexico. Moist air from the remnants of Barry moved northward into Texas. Precipitable water values over South-Central Texas increased to near record levels. A mid-level anticyclonic circulation developed and moved over Central Texas providing lift to generate thunderstorms. During the overnight period of July 3-4, a low-level jet streak set up over South…

Flash Flood · Jul 23, 2024. An upper-level trough moved across a stationary front and a very moist airmass. This combination generated thunderstorms. Some of these storms produced heavy rainfall that led to flash flooding.

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. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Kerr County

If a building in Kerr 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.
