TORNADOLERT - recommended for homes, trailers, apts, schools, nursing homes, cars, RVs, trucks and tornado shelters.  Faster and more reliable tornado warnings.  VIDEO of operation in homes and cars.

  • Tornadolert detects (low-frequency) infrasound emitted by approaching tornados. Infrasound, which is unheard by humans, travels without loss, even through solid walls.

  • A new tornado warning system under test by NOAA (US National Oceanic & Atmospheric Administration) is based on detecting tornado infrasound.

  • Other marketed sensors detect lightning, not tornados. However, only 10% of lightning-storms produce tornados.

  • Tornado-Warn Home detects 99.99% of tornado threats in homes, apartments, mobile homes and tornado shelters. Its back-up-battery powers operation in un-powered shelters

  • Tornado-Warn Car is alone in detecting tornados in moving cars and trucks.


".....TORNADOLERT sounded an alarm at 8PM.  We took shelter in a reinforced concrete structure in our backyard.  A rope tornado in front of 100mph wind had touched down 3 miles away severely damaging our house, but we were safe."  R.B. - Wichita,Kansas.
