Cosmic storm

A cosmic storm was a phenomenon which could interfere with TARDISes.

The Doctor's TARDIS was caught in a cosmic storm after the actualising filter ran out of Essence of Vallo and it crashed on Planet X. The Fourth Doctor later found that the energy from the storm had reactivated the actualiser. (PROSE: Famine on Planet X)

Another cosmic storm damaged the TARDIS controls, forcing the Doctor to land on Xaboi for repairs. (COMIC: Terror on Xaboi)

In 2157, the meteorite bombardment of Earth prior to the 22nd century Dalek invasion was attributed to a cosmic storm. (TV: The Dalek Invasion of Earth)
