Damaging storms can be made by creating a new race "natural hazards", and giving them sats that look like asteroids and are placed aboe and below the plane, inside storms.

Toss on shield depleting weapons, and the storm is shield depleting. Lightning rays for more deadly storms.

Put a second hazard race, and you can have them shoot at each other, so the storm dosen't go completely quiet when nobody is around.

Put insanely fast regen on them so they can't be killed...
