Next time you go out on a "dark and stormy night", you might want to bring along a safety net. Spectrum Electronics' "Thunderbolt Storm Detector" is a handheld, portable device that detects storm and lightning activity from over 75 miles away and then warns you about the storm's distance, approach speed, intensity, and estimated arrival time. This sort of device might have been super handy for victims of Hurricane Katrina, but it's even more practical for those with the means of quickly escaping these types of storms. And since it displays over 50 warning text messages, you'll know of every potential hazard well before things get rough.
