The problem with most outdoor warning systems

Most warning systems only alert you of one weather condition

Most outdoor warning systems only do one thing, forcing organizations to juggle multiple systems that don’t talk to each other when storms hit.

Perry Weather alerts of all weather threats in one system

Perry Weather combines lightning detection, NWS alerts, and on-site weather monitoring into one system that alerts your team with strobes, sirens, and custom PA messages.

How our Outdoor 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.

  • Weather stations automatically collect data

    On-site weather stations automatically track weather conditions delivering real-time data to the Perry Weather dashboard.

  • Fast, accurate lightning detection

    Perry Weather detects lightning utilizing the National Lightning Detection Network, the nation’s most reliable lightning detection network.

  • Tracks 50+ NWS alerts

    Perry Weather listens for over 50 national weather service alerts including tornadoes, flash floods, severe thunderstorms & more.

Create custom weather policies that trigger instant alerts

The Perry Weather will guide you through policy set up so that your warning system activates for only the weather conditions that impact your operations.

  • Policy setup done for you

    We’ll work with you to add your weather policies or create new ones that makes sense for your organization.

  • Create triggers to activate strobes, sirens and PA messages

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

  • Temporary access for contractors or seasonal employees

    Give temporary employees timed access to Perry Weather, so you don’t eat into your user count.

Get alerted the moment weather policies are triggered

The moment your weather policy thresholds are met, Perry Weather delivers real-time notifications to the right people, keeping your team ahead of the weather.

  • Automated sirens & strobes

    Trigger Perry Weather siren & visual strobes independently or simultaneously during policy-triggered weather delays with custom siren tones.

  • Schedule PA messages with specific instructions

    Schedule recurring PA messages with custom instructions so everyone is on the same page

  • Desktop and mobile notifications

    Perry Weather sends automated alerts to your team with step-by-step instructions when weather disrupts your operations.

Not every weather event deserves the same response

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 siren tones and alert messages

Lightning & high winds require different responses. Perry Weather allows you to select different siren tones followed by custom PA messages with details about the weather alert.

Trigger sirens, strobes or third party devices

Select which devices your weather policies should trigger. Sirens & strobes can be paired for higher risk weather events. Trigger external devices like irrigation systems with Perry Weather relays.

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.

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.

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.

Say goodbye to weather uncertainty 👋
