Superstorms and Hurricanes are both storms. Between the two, hurricanes are the only one that is a formal term for a storm. Superstorm does not have a formal definition, but the word is still used to describe weather conditions that cause signification impact, damage, and fatalities. Many meteorologists believe the term superstorm is overused. One difference between the two is the type of weather conditions that it forms in. Superstorms normally form in conditions that are colder, and the weather is less likely to be tropical. Hurricanes form in conditions that are warmer and in weather that is more tropical.
