When the Air Smells Like Ozone

If the air suddenly smells sharp, metallic, or like ozone during a storm, treat it as a lightning warning and get to shelter immediately. National Weather Service lightning safety material lists the smell of ozone, along with tingling skin, buzzing metal, and crackling sounds, as one of the warning signs that a strike may be seconds away. Lightning can split oxygen molecules in the air and create ozone, which produces that distinctive storm smell. If you notice it outdoors, especially with other warning signs, move to a substantial building or a hard-topped vehicle right away.
