The Storm is an entity in Fortnite present in Battle Royale and Save the World.
Save The World
The Storm can refers to the purple storm that wiped out 98% of the world's population at the beginning of Save The World's story. It creates monsters and has taken over Earth in Save The World. It is unknown how it formed in the first place, but it came to our world through the Rifts and seems to be hostile to any creature other than Husks, killing any creature that ventures inside.
In Battle Royale, the Storm is used as a barrier to keep players in the playable area and it will shrink until it is entirely closed in, dealing damage to players' health outside the Storm circle's perimeter. Any shield is ignored. The Storm’s visuals will intensify and appear more deadly as the match goes on.
The Storm is also what contains The Loop.

The Storm entered the Save the World universe through the Rifts, which spawn randomly in-game in various zones. Famed scientist Dr. Vinderman tried to prevent the Rifts from opening, but they came anyway and he died later in a lab experiment (in which he attempted to destroy a rift using a Singularity Pulse Bomb).
The Storm is able to produce evil clones of humans. This is shown in Save the World where it creates a husk based on the legendary gunslinger Blackboot Ayers. This ability is also displayed in the "Impostor!" questline, where the Storm gives Dennis an evil impostor.
In Battle Royale, the Cube is assumed to be a creation of (or otherwise related to) the Storm in Season 5, in which it made dark clones with the first being Brite Bomber, followed by Jonesy, Wild Card, Red Knight, Tricera Ops, and Rex.
Like in Save the World, the Storm is implied to be a sentient entity, due to its rage during The Device and how it is said to be "not just a storm".
