Arrakis is the most dangerous planet in the universe.  It is host to many extreme weather phenomenon.  The most dangerous being the Coriolis Storm.  With winds amplified by the planet's rotation, these storms shift the landscape itself.

Coriolis Storms sweep across Arrakis once a week.  They effect all of Arrakis by changing the locations of resource nodes. After the storm passes through the Deep Desert, players can discover new rock islands, shipwrecks, testing stations, and other points of interest. The monstrous storms provide players with infinite exploration opportunities. 

They also present a harsh reality for players who choose to establish bases in the Deep Desert.  Even the most well-built structures will fall to the punishing winds of the Coriolis Storms.  Players should build in the deep desert only with the expectation of it being a temporary outpost.
