You cannot predict when an event will happen, which one it will be and for a lot of events, what the best option to pick would be.

If you are happy to simply play around for a while waiting for the storm, feel free, but I personally would suggest you start again, and try working towards a new strategy.

I am currently playing on the hard level, and have had to restart my game many times as my strategy keeps changing depending on the problems I encounter. Part of the challenge with this game is to learn to plan for your skills to be available at the right times and working out which puzzles depend on others. I think it took me at least 4 games before I got things worked out to be able to solve all the puzzles on the normal level

Also, I do not know if there is an effect on changing the difficulty level mid-game. I am not having a lot of events in my difficult game, but then I have played normal games where I have had few events as well. Each game you play is unique, and each set of villagers will have slightly different personalities
