Everyone at one time or another has had the helpless experience of being caught where you would never want to be, caught in a thunderstorm. A storm that you didn’t know was even coming. And now you know from this website that the danger was there long before the first sign of a storm.

The hand-held ThunderBolt lightning warning system informs you of danger by the methods below:

• Detects all storm activity within 75 miles
• Identifies multiple storm cells, squall lines, and supercells through state-of-the-art lightning warning detection system technology
• Provides estimated time of arrival (ETA) at your location
• Calculates TIME TO CLEAR once a storm is near enough to be a threat
• Communicates through text messages, flashing lights, and user-selectable audible tone

• Waiting to see or hear the first stroke of lightning means that you've been at risk of a direct lightning strike for 30 minutes or more already.
  
  
• Waiting for 15-30 minutes after you think a storm has passed doesn't guarantee that the danger of lightning has passed. Storms can stall nearby, or new storms can move close enough to be a danger.
  
  
• The "counting method" of calculating the distance to a storm is almost always useless in determining exactly where and how many storm cells may be a direct lightning threat to you at a given moment.
