-If every water type gets it, then Dragon, Ground, Flying and Grass types will suffer immensely. Landorus and Garchomp usage will drop and Defog/Spin support will be more useful than ever.
-If only Ice types get it (ex. Cryogonal, Avalugg, Vanilluxe), then it won't affect the metagame too much, but those Ice types will see more usage outside of Hail teams and Hail teams in general will get a nice buff.
-If Fire types melt it upon being sent out (like Poison types and Toxic Spikes), then Fire types will be a staple on teams with Landorus, Garchomp, etc.
Lots of factors to consider.
