When National Weather service alerts are detected, such as tornadoes or flash floods, sirens & strobe automatically trigger with custom sounds and safety instructions.

Schedule PA Messages to support daily operations

Schedule text-to-speech PA messages to be sent through the speaker system on a recurring basis.

Trigger your system based on on-site weather data

When the weather conditions exceed your weather policy thresholds, trigger PA messages, strobes or sirens independently.

The warning system that adapts to your operations

No one operation is the same. Perry Weather lets teams respond to weather events in a way that aligns exactly with their emergency action plan.

Custom tornado siren tones and alert messages

How our Tornado Warning System works

The system gathers data from weather stations & the NWS

Unlike weather apps that rely on strictly public data, your dedicated Perry Weather station monitors conditions at your exact location.

  • Continuous tornado monitoring

    Perry Weather listens to the NWS tornado warning feed and matches every polygon against your geofence the moment it’s issued.

  • Tracks 50+ NWS alerts

    Tornado watches, severe thunderstorm warnings, and flash flood warnings feed the same system as the tornado warning itself so you can alert for more than just tornadoes.

Create custom tornado policies that trigger instant alerts

The Perry Weather team will guide you through policy setup so the warning system activates the right hardware and the right people every time.

  • Policy setup done for you

    We work with you to build the tornado response policy that makes sense for your operation.

  • Triggers for sirens, strobes and PA messages.

    Customize what hardware your weather policies should trigger, including sounds and custom messages.

  • Temporary access for contractors or seasonal employees

    Add temp users for the duration of a project so contractors hear the warning too.

Alert your team of tornado risks & other emergencies

Perry Weather delivers the warning to every channel at once, keeping your team ahead of the storm.

  • Automated sirens & strobes

    Trigger sirens and visual strobes independently or simultaneously during a tornado warning.

  • Schedule PA messages with specific instructions

    Play your pre-recorded shelter instructions through the speaker system the second the warning fires.

  • Desktop and mobile notifications

    Perry Weather pushes a tornado warning alert with shelter guidance to every subscribed phone and dashboard.

Frequently Asked Questions

How much does Perry Weather’s outdoor warning system cost?

Hardware pricing depends on the size of your location, the number of sirens, strobes, and PA speakers you need, and whether you’re adding on-site weather stations. Will work with you to pick software and hardware packages around your specific coverage requirements so you’re not overpaying for hardware or software features you don’t need.

Can I try Perry Weather’s weather monitoring and alerting software before purchasing hardware?

Yes. Perry Weather’s software platform works independently from the hardware, so you can start monitoring weather threats like lightning, setting custom policies, and receiving alerts for your locations before committing to a full outdoor warning system installation. It’s a great way to see how the platform fits your operation before scaling up.

Can I control sirens, strobes, PA messages, and mobile notifications independently?

Yes. Perry Weather lets you configure each alert type on its own. You might want strobes and sirens for lightning but only a PA message and mobile notification for an NWS watch.
Every combination can be tailored to match your weather policies so your team gets the right response for each specific threat.

How is Perry Weather’s outdoor warning system different from other solutions?

Most outdoor warning systems only cover one alert type, like lightning detection or NWS alerts. Perry Weather combines lightning detection, on-site weather station data, and NWS monitoring into a single platform, then delivers coordinated alerts through sirens, strobes, PA messages, and mobile notifications.
Instead of managing multiple vendors and disconnected systems, you get one platform that detects over 60 weather threats and tells your people exactly what to do.

What weather threats can Perry Weather’s lightning warning system alert me of?

Perry Weather monitors far more than just lightning. The platform tracks over 60 weather conditions including lightning, severe thunderstorms, tornadoes, flash floods, high winds, extreme heat, hail, and more.

It pulls from lightning detection networks, on-site weather stations, and National Weather Service alerts so your team is covered across the full spectrum of weather threats, not just one.
