According to tweets from the Fortnite data miner, the time rifts in Fortnite's sky will start closing later this week, and will totally vanish on or before Tuesday, August 21.

You can find a map below showing all the rift spawn locations on the Fortnite Battle Royale map. The map was created and shared in a post online by Twitter user Squating Dog.

There aren't a ton of rifts on the map, though. Previous seasons have seen rifts all over the place, but they're much rarer now. Here's where they can be found in Fortnite Chapter 3 Season 4.
