Summer storms over the Great Lakes can produce magnificent lightning, as Duane Clausen captured in this shot of a July thunderstorm over Lake Michigan. A lightning strike can deliver 100,000 amperes of current at millions of volts, and heats the surrounding air to tens of thousands of degrees C. Lightning is the #2 storm killer in the U.S., behind floods, killing more people than hurricanes and tornadoes combined, on average. Avoid water, high ground and open spaces - stay indoors during a storm and away from the telephone or plumbing fixtures.
