The Hailstorm weather condition was introduced in the third generation of Pokémon games (RuSaEmFRLG). It can be brought about by use of the move Hail (TM07) or by the ability Snow Warning.

Any Pokémon with Ice as its type (or part of its typing) will not recieve damage from the storm (it will also be protected from the storm's affect if it has the ability Snow Cloak). If the Pokémon does not have that type (or the aforementioned ability) it will lose 6.25% (1/16) of it's health at the end of every turn.

icy rock A Pokémon holding the item Icy Rock will prolong the duration of a Hailstorm for three more turns than normal (from five turns to eight turns).
