A Pokémon with Snow Warning summons a hailstorm when it enters battle. The hailstorm won't end unless another weather condition is entered into play by way of the moves Rain Dance, Sandstorm, or Sunny Day, or a Pokémon with the Drizzle, Drought or Sand Stream Abilities enters the battle.
Starting in Generation VI the effects of Snow Warning last for five turns.
Snow Warning doesn't have an effect in the overworld.
