Texas has more flooding deaths than any other state in the country. The state’s geography — particularly the Hill Country and Edwards Plateau, known as Flash Flood Alley — creates conditions where rainfall rapidly becomes lethal flash flooding with little warning. Knowing how to access real-time Texas flooding maps, understanding flood alert systems, and recognizing the highest-risk areas can save your life.

Flash Flood Alley – Texas’s Highest-Risk Region
Flash Flood Alley refers to the belt of central Texas where geography and climate combine to create extraordinarily dangerous flash flood conditions. The region runs roughly from Del Rio northeast through San Antonio, Austin, and into the Hill Country — encompassing the Edwards Plateau and its transition zone where the limestone plateau gives way to the coastal plain.
Three factors make Flash Flood Alley uniquely dangerous. First, the region’s shallow, rocky soil absorbs very little rainfall — water runs off quickly rather than soaking in. Second, the steep terrain of the Hill Country channels runoff rapidly into rivers and creeks. Third, Texas’s location creates conditions where Gulf moisture can produce extreme rainfall events — particularly when tropical moisture is funneled inland. The Guadalupe, Llano, Pedernales, Blanco, and Nueces rivers are all historically prone to catastrophic flash floods.
The July 2025 Texas Flooding – Affected Areas
The July 4, 2025 flooding was one of the most geographically widespread Texas flood events in modern history. Here are the primary affected areas:
Kerr County (Hardest Hit)
The Guadalupe River communities of Kerrville, Hunt, Center Point, Ingram, and Comfort experienced the most catastrophic flooding. The river crested at 34.3 feet in Kerrville — the third-highest on record — and at a record 37.5 feet in Hunt. Camp Mystic, located along the Guadalupe River southwest of Hunt, suffered 28 deaths. Campgrounds and RV parks along the river, many filled with families celebrating the July 4 holiday, were also severely impacted. Debris swept miles downstream, including vehicles that were still occupied when they entered the river.
Travis County (Austin Area)
Travis County experienced significant flooding approximately 150 miles east of Kerr County, with at least 9 confirmed deaths. Lake Travis — the Highland Lakes reservoir system’s primary flood control reservoir — absorbed significant inflow. Multiple low-water crossings in the Austin area became impassable. The Barton Creek and Colorado River systems both rose well above flood stage.
Burnet and Williamson Counties
Burnet County in the Colorado River watershed saw 5 deaths, while Williamson County north of Austin recorded 3 fatalities. Georgetown, Round Rock, and Leander areas all experienced high-water events as rivers in the drainage basin north of Austin swelled with runoff from the Hill Country.
Understanding Texas Flood Warnings – What Each Level Means
| Alert Level | Meaning | Action Required |
|---|---|---|
| Flood Watch | Conditions are favorable for flooding to develop | Monitor conditions; prepare to act |
| Flood Warning | Flooding is occurring or imminent in the area | Move to higher ground immediately in flood-prone areas |
| Flash Flood Warning | Flash flooding is occurring or expected soon | Move to higher ground immediately; do not drive through water |
| Flash Flood Emergency | A rare, catastrophic event; extreme threat to life | Take immediate life-saving actions; move to highest level of shelter |
Texas FEMA Flood Zones – Understanding Your Property Risk
FEMA maintains flood insurance rate maps (FIRMs) for all Texas counties that show flood hazard zones. The key zones to understand are Zone AE (high-risk, 1% annual chance of flooding — the 100-year floodplain), Zone X (moderate to minimal risk), and Floodway (the channel of a river plus adjacent areas that must be kept free from encroachment). Properties in Zone AE are required to carry flood insurance if they have federally backed mortgages. Critically, Camp Mystic’s Guadalupe campus buildings were mapped in the Floodway on Kerr County’s 2011 FEMA map — the highest-risk designation available.
Search your property’s flood zone at msc.fema.gov. For flood insurance, contact the NFIP at 800-427-4661 or your insurance agent. For more on the July 2025 disaster, read our detailed Texas flood death toll breakdown and our full account of what happened at Camp Mystic.
Frequently Asked Questions – Texas Flooding Map
Where can I find a current Texas flooding map?
Current Texas flood conditions are available at water.weather.gov (National Weather Service Advanced Hydrologic Prediction Service), floods.org, the Texas Water Development Board at waterdatafortexas.org, and local NWS offices. Google Maps also shows flood alerts in real time.
Which areas of Texas flooded in July 2025?
The July 2025 floods primarily affected the Hill Country counties of Kerr, Burnet, Williamson, Travis, and Tom Green. Kerr County was hardest hit, particularly the communities of Hunt, Kerrville, Center Point, Ingram, and Comfort along the Guadalupe River.
What is Flash Flood Alley in Texas?
Flash Flood Alley is the informal name for the region of Texas and Oklahoma where flash flooding is most frequent and deadly. It runs roughly through the Hill Country and Edwards Plateau — the area including Kerrville, San Antonio, and Austin — where steep terrain and rocky soil funnel rainfall rapidly into rivers.
How do I sign up for Texas flood alerts?
Sign up for emergency alerts through your county’s emergency management office or the Texas Division of Emergency Management at tdem.texas.gov. Wireless Emergency Alerts (WEA) are automatically sent to cellphones in affected areas. Many counties also offer opt-in text or email alert systems.
What is the National Weather Service flood warning system for Texas?
The NWS issues flood watches, warnings, and flash flood emergencies through local forecast offices. Flash Flood Emergencies are the highest-level alerts, indicating life-threatening flash flooding is occurring. Monitor alerts at weather.gov and download the NWS app for push notifications.
