Niantic has announced beginning later this week, 50 Hoenn Pokemon including Treccko, Torchic, and Mudkip will be introduced into Pokemon GO.
The rest of the Hoenn region Pokemon (135 in total) will be available in the future. At the same time, a new feature called Dynamic Weather has been added into Pokemon GO. If it’s raining in the real world, it’ll rain in Pokemon GO too. If it’s snowing, it’ll snow in Pokemon GO.
The weather will affect the Pokemon that appear, certain attacks will be more effective, and the appearance of the map. Check out the trailer and Dynamic Weather image below.
