How Real County floods

Flash flooding from severe storms dominates the flood risk in Real County, accounting for 99 recorded events and four deaths over the last 30 years, compared to just one standard flood event. Severe weather events, such as the flash floods driven by tropical moisture and training thunderstorms in July 2025, illustrate how rapidly heavy precipitation can accumulate across the Texas Hill Country.

National Flood Insurance Program records indicate that flood risks extend beyond high-risk areas. Zone A has accumulated the highest number of claims with 42 filings, averaging $13,616 per payout and an average recorded water depth of 4 inches. Meanwhile, unshaded Zone X properties have recorded an average water depth of 28 inches across 10 claims, with average payouts of $15,247. Additional claims are distributed across unknown zones, Zone X, and shaded Zone X.

Homeowners and real estate agents managing properties in designated Zone A high-risk areas, as well as those in unshaded Zone X locations experiencing significant average water depths, should pay the most attention to flood insurance and mitigation.

Where the flood claims came from

21% of Real County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Flash Flood · Jul 15, 2025. A mesoscale convective vortex developed over northern Mexico and sent an outflow boundary into South-Central Texas. Thunderstorms in this complex 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.

Flash Flood · Aug 31, 2022. A mid to upper level low moved over a warm, moist airmass in South Central Texas and generated slow moving thunderstorms. Some of these storms produced heavy rain that led to flash flooding.

The zones you’ll see on the map

Flood insurance in Real County

If a building in Real 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.
