Ion storm

An Ion storm was a weather effect caused in some way by [[Tiberium]. Unfortunately, extremely little is known about them. In fact, they must be described only by their effects. Effects include:

All aircraft and hover vehicles shut down during an ion storm, and Aircraft plummet to the ground when an ion storm sets in if not already grounded.

Giant lightning bolts impact the ground at all numerous locations, seemingly randomly.

Radar is inoperative.

The exact mechanism for these effects is unknown.
