Troubling Rain and Bullet Rain had made it to the edges of the wind zone. The two characters didn't enter it and head directly towards the three players in the middle. Instead, they continued to move forward.
The length of distance traveled was according to the research Team Blue Rain had done on this map. If the two players had chosen to directly cut into the wind zone, they would be at a 90 degree angle with the strong winds. Even if they weren't facing against the wind, their movements would still be hindered. By moving a bit more forward, they could position themselves into a better angle and borrow the wind for support.
