Austin Weather Radar - Live Doppler Map (TX)

🌦️ Austin Weather & Live Doppler Radar Guide

Austin is situated in Central Texas at the intersection of the rolling Texas Hill Country and the Blackland Prairie. Known for its vibrant culture and warm climate, Austin is also located squarely in 'Flash Flood Alley.' The city's geography, with the Colorado River and dozens of steep tributary creeks like Barton Creek and Shoal Creek, makes it susceptible to rapid, dangerous flash flooding during sudden convective rain events. Real-time Doppler weather radar provides essential visibility into storm intensity, movement, and severe thunderstorm warnings across Travis, Williamson, and Hays counties.

📡 NOAA NEXRAD Station: KGRK (Fort Cavazos / Austin, TX)

Our interactive Austin radar connects directly to NOAA's Level-III NEXRAD radar station KGRK, located at Fort Cavazos (Killeen, TX), with supplementary coverage from station KEWX in New Braunfels. Station KGRK features dual-polarization S-band Doppler technology, enabling precise tracking of severe hail cores, torrential precipitation rates, and damaging straight-line winds across Central Texas.

🎨 How to Read Doppler Reflectivity (dBZ Scale)

Radar reflectivity measures precipitation density in decibels of Z (dBZ). Use this color reference when monitoring approaching storms on the Austin radar:

⚠️ Seasonal Severe Storm Threats in Austin

Spring brings intense supercell thunderstorms fueled by the clash between moist Gulf air and dry desert air along the West Texas dryline. These storms can produce golf-ball to baseball-sized hail and damaging microbursts. Autumn and late summer can bring heavy rains from decaying tropical systems moving inland from the Gulf.
