Floods and hurricanes usually can be predicted, but lightning storms often arrive unexpectedly. Sometimes dark clouds are seen and thunder is heard in the distance, indicating that a lightning storm may precede a rainstorm. On the whole however, lightning storms occur suddenly and, if struck, can paralyze and/or kill you.
Lightning is defined as an atmospheric discharge of electricity that typically occurs during thunderstorms. It always seeks the shortest path to the ground, so it nearly always hits the tallest object in an area.
