Tracking severe weather in Texas isn't as simple as opening a radar app and hoping for the best.
I spend a lot of time watching storm development across Central and South Texas. The flat terrain that makes this state great for agriculture also makes it one of the most tornado-prone areas in the country. When warning systems activate, the difference between someone staying safe and someone getting hurt usually comes down to one thing: having reliable, real-time information before the sirens start blaring. The National Weather Service operates a network of Doppler radar sites across Texas, with primary coverage points in Amarillo, Fort Worth, Austin/San Antonio, Houston/Galveston, and Corpus Christi. These feed into the NWS Storm Prediction Center's mesoanalysis products, which track rotating thunderstorm complexes in real time. The Storm Prediction Center publishes convective outlooks three times daily, with hourly updates during active severe weather periods. For live map data, the best single source is the NWS warning polygon system at weather.gov. It overlays county-level tornado warnings, severe thunderstorm warnings, and mesoscale discussions in a way that avoids the clutter you get from commercial weather apps. When a tornado warning drops for your county, the polygon tells you the exact path the storm is projected to take, usually with a confidence window of about 1.5 miles on either side of the predicted track.
Here's where things get tricky and most people get it wrong. Tornado warnings are not the same as tornado watches. A watch means conditions are favorable for tornado formation in a broad area, potentially spanning dozens of counties. A warning means a tornado has either been spotted by someone on the ground or detected by radar as a rotating updraft. The difference matters because during a watch, you prepare. During a warning, you take shelter immediately. I learned this distinction the hard way back in April 2019 when an outflow boundary pushed into Comanche County around 6 PM. The radar showed a developing hook echo over the southern edge of the county. My phone didn't have location-based warning alerts enabled, so I was relying on a radio I'd set up years earlier for amateur satellite work. The NWS Fort Worth office issued a tornado warning at 6:14 PM. The storm hit a small unincorporated community about twelve minutes later. By the time I got an alert on my phone from a different app, the warning had already upgraded to a confirmed tornado report. The workaround I use now is running multiple redundant feeds. A battery-powered NOAA Weather Radio tuned to the appropriate NWS partition is my primary alert system. I keep a second device, an older Android phone with cell broadcast alerts forced on, in a grab bag near the bedroom door. And every few days I check the Storm Prediction Center's own graphical product page directly in a browser because sometimes the push notification infrastructure glitches during high-volume warning events. It's a pain. It keeps you alive.
When you're looking at live map data during an active event, pay attention to the velocity couplet on the NWS radar visualization. This shows inbound and outbound wind speeds within a storm cell. A tight couplet with opposing colors separated by one radar bin usually indicates rotation. The stronger the velocity difference, the more intense the rotation tends to be. This is a radar-derived signature, not a confirmed tornado, but it correlates well with actual tornado formation, especially in supercell storms common to North and Central Texas. Ground truth remains the gold standard though. Visual confirmation from spotters or from yourself overrides any radar interpretation. There have been documented cases, particularly in the late fall and early spring, where tornadic storms produce brief ground contact without a strong velocity couplet visible on the regional Doppler network. The radar beam itself can overshoot low-level rotation when storms are far from the site, which is why the NWS relies heavily on trained storm spotters in those scenarios.

What to do when a warning hits your county
The standard guidance from FEMA and the Red Cross is straightforward: go to the lowest level of a sturdy building, away from windows, doors, and exterior walls. An interior room or hallway on the lowest floor works. If you're in a mobile home, you leave it and find a permanent structure. If you can't find one, lie flat in a ditch or depression and cover your head. Vehicle underpasses are sometimes suggested but they carry their own risk of flooding and debris, so they're not a reliable fallback. One thing most people don't consider is the timing. Tornado warnings today often have a lead time measured in minutes rather than the half hour or more you might see for a developing system in ideal conditions. The median warning lead time across Texas is somewhere around eight to twelve minutes depending on the region. That means you need to know where your shelter is before the alert sounds, not after. Walk through your home or workplace and identify the safest room while conditions are calm. Keep a go bag with water, a flashlight, and sturdy shoes near that room if possible. Driving during active tornado season in Texas changes the risk profile entirely. If you're on Highway 281 between Killeen and Waco or any similar rural corridor and you see the sky turning green or the wind picking up erratically, don't try to outrun it. Pull over to a sturdy building if you can reach one within two minutes. If you can't, get out of the vehicle and lie flat in the nearest ditch or depression. Debris from damaged structures traveling at highway speeds is the leading cause of tornado-related injuries and fatalities when people are caught in cars.
Limitations of what you can actually track online
No live map or warning system is perfect. The radar coverage gap between the Fort Worth and Austin sites can leave parts of East Central Texas without good Doppler data during fast-moving storm events. The warning polygon system sometimes issues overly broad polygons during initial warnings, then refines them as the storm path becomes clearer. Commercial weather apps like Weather Channel or AccuWeather pull from the same NWS data but add their own layers of processing that can delay warning messages by thirty seconds to two minutes compared to the raw NWS feed. In a tornado situation, two minutes is a meaningful difference. If you live in a rural area outside dense radar coverage, consider supplementing with a dedicated storm spotting service or a local amateur radio net. Some ham operators in Texas participate in SkyWarn programs coordinated with NWS offices, and they can provide ground observations that fill gaps in the automated warning system. It takes a small investment in equipment and training, but it pays off during events where the radar picture is ambiguous or delayed. Check the actual NWS office pages for your specific county. Their forecast discussion pages often contain nuanced reasoning about why a warning was issued or why conditions didn't meet the threshold, and that context is useful for understanding the broader setup beyond just the warning polygon on a map.
