At the edge of Lake Maracaibo, Venezuela, a storm has returned night after night for centuries. It produces almost 250 lightning flashes per km2 per year - more than anywhere on Earth. Sailors gave it a name: the Beacon of Maracaibo. It fires 140 to 160 nights a year, for up to 9 hours a night. Zulia state put a white lightning bolt on its flag.
