A howling storm of thick snow and ice crystals appears in a cylinder 40 feet high and 40 feet in diameter. The area is heavily obscured by the swirling snow. When the storm appears, each creature in the area takes 8d8 cold damage, or half damage with a successful Constitution saving throw. A creature also makes this saving throw and takes damage when it enters the area for the first time on a turn or ends its turn there. In addition, a creature that takes cold damage from this spell has disadvantage on Constitution saving throws to maintain concentration until the start of its next turn.
