subtropical storm

Hybrid tropical system

A subtropical storm is a weather system with characteristics of both tropical and extratropical cyclones—drawing energy from warm ocean waters like a hurricane but also from temperature contrasts in the atmosphere.

These storms typically have a broader wind field and less organized structure than fully tropical systems.

Meteorologists sometimes reclassify them as tropical storms if they develop further: The subtropical storm transitioned into a hurricane as it moved over warmer waters.
