If you have a sweet addiction to Candy Crush Saga, you're in for an even sweeter treat throughout the week. Developer King is kicking off a week-long event in which sugary treats will rain down on players from the cotton candy clouds. King is incredibly vague about what will be dropping from the clouds this week, but the company does say to keep checking back for gifts:

All week long, sweet gifts will pour down from the cotton candy clouds. Be sure to come back to the game, because you never know when it'll rain…

It's likely that "rain" will include plenty of boosters and things to help you progress through a level you may be stuck on. In any case, the event will run the entire week, from August 17 through August 22, so you have enough time to hop in for some extra sweet treats.
