I have over 5k hours playing the game. Since the last update I have played few games, and seems like summers are now a continuum of thunderstorms and rain and then thunderstorms and rain again. If thunderstorm ends with rain starting, then when raining ends another thunderstorm usually begins. I don't think it's a great challenge but only really, really boring. It gets very annoying to hear another wind blowing sound effect a minute or two after the previous one ended and all fires were put out.
Maybe there could be less but heavier thunderstorms instead?
