Global weather intelligence

GLOBAL WEATHER.REAL-TIME INTELLIGENCE.

Monitor severe weather, tornadoes and storm cells — and connect a global network of voluntary trackers. StormNet turns meteorological signals into a clear risk assessment.

What is StormNet?

A global severe-weather monitoring system.

StormNet processes weather data from several sources and tries to identify dangerous weather developments as early as possible. Instead of a single number, it builds a picture from many signals and turns them into a risk assessment.

It never claims to predict a tornado with absolute certainty. Meteorology is probabilistic — StormNet shows you where conditions are dangerous, and how confident the assessment is.

Risk assessment, not certainty.

Analysed signals

  • Weather stations
  • Radar
  • Satellite data
  • Wind
  • Temperature
  • Air pressure
  • Humidity
  • CAPE
  • Wind shear
  • Storm cells
  • Radar signatures
  • Tornado indicators
  • Movement direction

Available signals depend on the data sources your API server is connected to.

Features

Everything the desktop app, the tracker and the network can do.

  • Tornado detection

    Detects and rates possible tornado activity from a combination of meteorological signals.

  • Live radar

    Radar information and storm-cell movement rendered on an interactive map.

  • Satellite

    Satellite data integration to observe large-scale weather development.

  • Global monitoring

    Weather data from many regions around the world in one interface.

  • Live map

    Interactive map with storms, tornadoes, trackers and warnings.

  • Heatmap

    Visualises risk areas and the regions currently affected.

  • Movement tracking

    Follow the movement of storm cells and tornado signatures over time.

  • Tracker network

    Android devices can voluntarily join the global tracker network.

  • Live GPS

    Trackers can transmit their position to the API server — always opt-in.

  • Compass

    The Android app includes an integrated live compass.

  • Emergency system

    Trackers can report emergencies and tornado observations.

  • Last message

    Record a last voice message and transmit it to authorized trackers.

  • Communication

    Trackers can communicate with each other through the network.

  • 3D globe

    Global visualisation of weather activity and connected trackers.

Tracker network

ONE NETWORK. MANY TRACKERS.

Android devices can voluntarily act as trackers. A tracker is a participant in the network, never a hidden sensor — every transmission is something the user switched on.

  • Transmit GPS
  • Receive weather & hazard info
  • Discover nearby trackers
  • Receive emergency events
  • Create emergency events
  • Send tornado turning reports
  • Receive messages
  • Communicate with trackers
  • Use compass data

Emergency system

WHEN SECONDS MATTER.

The emergency button lets a tracker raise an alert in two ways: reporting an accident, or reporting a tornado turning with the observed direction. The report is transmitted to authorized trackers within the configured radius.

🚨 ACCIDENT🌪 TORNADO TURNING

Emergency events are user reports — they are not automatically confirmed rescue operations. Always call your local emergency number first.

Last message

YOUR LAST MESSAGE CAN BE HEARD.

The Android app offers a "Last Message" function. You record a voice message yourself, and only after you confirm it does the app transmit it. There is no hidden microphone recording — recording always starts with a user action.

The message is stored on the API server and can be managed according to the retention time configured by the operator.

Architecture

How the system fits together.

The API server is a standalone Java JAR. The desktop app is not the server — it is a client. The API server runs separately and handles communication, authentication and data storage for every client.

FAQ

Frequently asked questions

What is StormNet?

StormNet is a global weather and severe-weather monitoring system. It processes weather data from several sources and tries to identify dangerous weather developments early. It consists of a desktop application, an Android tracker app and a separate Java API server.

How does tornado detection work?

The system combines meteorological signals such as radar signatures, wind shear, CAPE, pressure, humidity and storm-cell movement into a risk assessment. It is an estimation of probability — never a guarantee that a tornado will or will not occur.

Is the system an official weather warning service?

No. StormNet is not an official meteorological or emergency service and does not replace official warnings. Always follow your national weather service and local authorities.

What is the Tracker Network?

A voluntary network of Android devices. A tracker can transmit GPS, receive weather and hazard information, discover nearby trackers, receive and create emergency events and communicate with others.

Does the Android app track my location?

Only if you enable it. GPS transmission, background tracking and nearby discovery are separate opt-in settings.

Can I disable location tracking?

Yes. Every tracking feature can be switched off in the app at any time, and the phone number is controlled separately.

What is the Emergency Button?

A button in the Android app to report an accident or a tornado turning observation, including a direction. The report is sent to authorized trackers within the configured radius. Emergency events are user reports, not confirmed rescue operations.

What is Last Message?

An optional voice message you record yourself. After you confirm it, it is sent to the API server and broadcast to authorized nearby trackers. The app never records without your action.

Where is my data stored?

On the API server that the operator of your network runs — a standalone Java JAR. This website only hosts the public downloads.

How long are Last Messages stored?

According to the retention time configured on that API server. The operator can manage and delete stored messages.

What platforms are supported?

A Windows desktop application (Windows 10 / 11), an Android tracker app and a web dashboard served by the API server.

Safety

SAFETY FIRST.

This system provides weather intelligence and user-generated observations. It does not replace official emergency warnings, meteorological services or emergency responders.

During dangerous weather, always follow official warnings and local authorities. A tornado risk assessment is never a guarantee.
