ELECTRICAL FIREBALL 😳⚡️: The fireball is actually a plasma arc, or an arc flash. It’s likely formed by a fault current in the line which can be caused by strong winds, or a tree branch hitting lines and making them come together. Once a plasma ball (the arc) forms, it’s usually self-sustaining. This happened in St. Petersburg on Sunday. #severeweather #powerlines #fireball #electricity #stpetersburg #florida #flwx
