Orohro

The Kanohi Tempesta was the Mask of Weather Control. It allowed it's user to manipulate and change the local weather.

Description
Upon activation, the user is given near-perfect control over the weather's conditions. They can create mists, move clouds, start or stop rainfall, hailing and snowfall, induce thunderstorms and produce winds. They have these abilities for around two minutes or until their concentration is broken. Once their duration of weather control is depleted the weather will return back to it's natural course.

The mask has an alternate power, which is always active, which will notify the user of incoming storms through buzzing and ringing. While the user can summon storms, they are not able to create destructive ones, and are unable to direct any lightning, hail, or fierce winds they may create. Rather, the user must contain the weather they created. This makes it one of the hardest Great Kanohi to use correctly.

Trivia

 * The Tempesta was based off of the Rahkshi power of Weather Control, as well as the powers of the character Storm from the X-Men franchise.
 * On rare occasions, if a very destructive storm such as a hurricane or a massive thunderstorm is incoming, the mask's weather predicting ability will make awful, bone-chilling noises. This is inspired by the SAME heading noises at the beginning of an EAS alert, which are known to be frightening and nightmare-inducing.
