GT Sport on PlayStation 4 is getting more wet-weather tracks according to Gran Turismo creator Kazunori Yamauchi.

The racer currently has only one wet-weather location: Northern Isle Speedway. Luckily, more tracks are on their way to the PS4 exclusive, as confirmed by Yamauchi in a recent interview with website GTPlanet. According to the creator of the Gran Turismo series, all of the cars in GT Sport are already compatible with rain, and it’s only a matter of adding wet conditions to a track.
