Dangerous Thunderstorm Alerts provide the most advanced alerting to severe weather with lightning --  powered by total lightning detection.

When it comes to protecting life and property from severe weather, minutes matter.

Whether you’re a parent watching your kids playing soccer on the field, a county official managing the safety of attendees during an outdoor county fair, or a school administrator in charge of keeping thousands of students safe, having the earliest possible notification of approaching severe weather can mean the difference between life or death.

Our advanced technology provides the fastest alerts to approaching severe weather with lightning.

Monitoring Total Lightning

The vast majority of lightning stays in the sky and jumps from cloud-to-cloud. Meteorologists and climate scientists have long known that this in-cloud lightning is an early sign of impending severe weather.

Knowing that in-cloud lightning plays a role in the formation and intensity of many kinds of extreme weather, we established the world’s largest and most advanced lightning sensor network.

The sensors in our network continuously monitor, calculate and report where and when lightning strikes occur in the clouds or on the ground – what meteorologists call total lightning.

Issuing Severe Weather Alerts

Total lightning detection makes it possible to deliver our exclusive Dangerous Thunderstorm Alerts (DTAs). DTAs are issued automatically to WeatherBug app users and enterprises across many industries – including schools and universities, sports and recreation, emergency response, aviation and more – wherever and whenever the weather plays a key role in safety and operations.

When Minutes Matter

DTAs are 50% faster, on average, than other alerts.  These severe weather alerts are issued when our Total Lightning Network™ detects high rates of lightning, which indicate increased potential for potentially dangerous conditions such as:

  • Cloud-to-ground lightning strikes
  • Heavy rain
  • High winds
  • Microbursts
  • Hail
  • Tornadoes

How DTAs Work

We issue Dangerous Thunderstorm Alerts when lightning detection rates exceed a predetermined threshold. Detailed weather bulletin information is also provided within the text alert. DTAs are updated every 15 minutes until the dangerous weather is no longer a threat, and the alert expires.

Know Before™

DTAs are issued on all WeatherBug apps and online at www.WeatherBug.com. Our enterprise customers see DTAs visually depicted in StreamerRT by a purple polygon encompassing the alert area. The polygon displays the area, size, direction and speed of the severe lightning activity.

Along with DTAs, we also issue watches and warnings from the National Weather Service (NWS) through our line of WeatherBug apps and enterprise tools. DTAs do not supersede the alerts issued by the National Weather Service, and should be used together to help enhance severe weather notification and alerting for information and safety.
