When a Pokémon with the Sand Stream Ability enters a battle, a Sandstorm starts to rage on the battlefield. This Sandstorm will continue to rage until another Pokémon uses a move to change the weather, or a Pokémon with the Drizzle, Drought or Snow Warning Abilities-or with a Pokémon with the Abilities Air Lock or Cloud Nine-enters battle.
Starting in Generation VI, the effects of Sand Stream will last for 5 turns.
Sand Stream doesn't have an effect in the overworld.
