Generations IV and V
Snow Warning summons a hailstorm in battle as soon as a Pokémon with Snow Warning enters the battle. Its effects are the same as Hail, but instead of lasting for five turns, it lasts for the whole battle until replaced. If a Pokémon with Snow Warning is sent out in the same turn as another Pokémon whose Ability affects the weather, the slower Pokémon's Ability will override the faster Ability.
In Generation VI, the hail will last only for five turns instead. This can be extended to eight turns if the Pokémon is holding an Icy Rock.
If heavy rain, extremely harsh sunlight, or strong winds are present, Snow Warning will fail to activate.
Outside of battle
Snow Warning has no effect outside of battle.
