At first, this ability is reflexive, and will produce a storm whenever one is angry, frightened, worried or stressed. However, it would eventually be possible to control this, both to prevent reflexive creation and to create storms at will. The standard form of storm produced is a lightning and rain storm, but other forms are also possible with more experience - e.g. sandstorms, hurricanes, tornadoes, hailstorms, blizzards, typhoons.
