At the moment its snowing quite a bit in the Netherlands. Unfortunatly, every bit of snow falling causes our weather institutions to go in panick mode and it shoves out a weather alert, code yellow orange or red. Red actually warents real world caution. Orange only when its freezing (slippery on the road when driving a car). Yellow can be ignored all together.
For me however none of these alerts should have an impact on PoGO. If its to bad weather to go outside, people will just not go outside. And if they do… so what? You should be rewarded for walking arround in the cold, not have some warning tell you that pokemon dont like the weather.
The weather settings and pokemon who like them are just introduced. It makes zero sense that they wouldnt like their extreme variant of that weather setting.
Its snowing, but ingame all i see are green fields, buildings, and that ugly red exclamation mark telling me i shouldnt play right now.
