Tornado warnings can sound like outdoor mechanical sirens, broadcast-style attention tones, or narrow-band radio alerts. To get a clip that reads as "real" in context, decide what system is making the sound, where the listener is standing, and how clean or masked it should be. Use the sections below to copy prompt language that produces the right wobble, bandwidth, and tail for your scene.
Pick the warning system first
A municipal outdoor siren feels physical and oscillating, while an EAS-style tone is steadier and more electronic. The right choice depends on what the audience should recognize instantly.
- Use "mechanical rotating siren, pitch wobble" for outdoor networks
- Use "EAS attention tone, clean beeps" for broadcast/interrupt moments
- Use "weather radio, narrow band, light static" for handheld realism
Match perspective: close, distant, or indoors
Perspective sells the shot. Close sirens have sharper transients and stronger midrange; distant ones lose highs and feel less wide; indoor ones are muffled with subtle reflections.
- Add "distant across town, rolled-off highs" for exterior wide shots
- Add "heard through windows, muffled, small-room reflections" for interiors
- Ask for "mono-compatible" if it must translate on phones and TVs
Dial in harshness and masking
Tornado warnings often sit against wind, rain, or noisy crowds. Decide whether you need a clean cut-through alert or a more realistic, partially masked layer.
- For clarity: "low noise floor, no distortion, controlled high end"
- For realism: "light hiss/static, slight speaker distortion"
- For storm beds: "partially masked by wind, siren still readable"
Avoid common "fake siren" giveaways
Some sirens sound like generic police/ambulance cues or overly musical synths. A tornado warning should feel steady, repetitive, and utilitarian without melodic movement.
- Avoid "melodic siren" or obvious police two-tone patterns
- Avoid extreme sub-bass rumble unless your scene is truly cinematic
- Avoid long reverb tails that imply a cavernous space outdoors
