How close is the lightning?

You can do a rough calculation this way:

  1. When you see the flash, begin to count the seconds until you hear the thunder.
  2. Divide this number by 5.
  3. The number you get is the approximate distance of the lightning in miles.

For example, if you count nine seconds between the flash and the thunder, the lightning struck just under two miles away.
