WeatherBug’s exclusive SparkTM is your personal lightning detector – delivering minute-by-minute, mile-by-mile lightning strike information so you can enjoy the outdoors and stay safer.

As visually stunning as it is useful, Spark displays real-time lightning data from the company’s exclusive Total Lightning Network, the largest and most advanced in the world. See where the closest lightning strike is to you and heed color-coded warnings to avoid danger. Zoom out, and view lightning flashes around the world.

What is Spark? WeatherBug’s Spark is the only mobile tool that taps into real-time readings from the world’s largest and most advanced Total Lightning Network to tell you how close the nearest lightning is to you – whether it’s a few miles away, across the country, or thousands of miles away in another country!

How does it work? By combining real-time lightning data, cloud computing power, and the GPS on your device, Spark delivers lightning strike information for your current city, your saved locations, or on the spot – whether you’re at the beach, ballpark or golf course.

Earth Networks, the parent company of WeatherBug, tracks lightning strikes around the world using its exclusive Total Lightning Network. In fact, the National Weather Service (NWS), the United States Air Force Weather Agency, and NASA Goddard Space Flight Center's Wallops Flight Facility all use data from our network – the same data that we are delivering to WeatherBug users for their personal enjoyment and safety on their mobile devices.
