Besser gesagt alle Pflanzen du nur nen halben Stern haben können kaputt gehen. Also auch Gras Düngen sonst gehts kaputt (und wahrscheinlich nach jedem Sturm neu Düngen) Insgesamt soll man maximal 4 Stürme im Jahr haben. Manche triggern auch auf einem Festival Tag und kommen daher gar nicht...
Hier mal nen kleiner Ausschnitt von Fogu:
The weather is pretty much set in advance, so you can't simply reload your save game to try and avoid a specific weather type. Festival days will always be sunny even if the weather report was predicting something different for that day.
Stormy weather is not kind to crops, animals, or your health! A typhoon or blizzard will reduce the Star Rank points of a crop by 5 points. Any crop that has very low Star Points (SP), such as pasture grass that typically only has 1 SP (.5 stars), can be destroyed by a bad weather storm. You can fix the damage to your crop by applying Fertilizer, although you can't fertilize pasture grass; you'll simply have to replant it if necessary.
Your farm animals should remain indoors during a bad weather storm (or even when it is raining, but snowing is okay to go outside). They can receive between +20 and +40 stress points if they're outside, and -5 to -20 friendship points. Pets will get a -2 FP hit if you take them outside during a storm.
A storm will also decrease your heals by 10 points when you step out into it for the first time that day, but you can easily restore that by eating food. Using your tools will also use more stamina.
Storms will occur during Summer season (typhoons) and Winter season (blizzards). At most, you'll only experience four storms during those seasons. If you haven't experienced a storm by the 26th of the season, you will have one trigger on the 27th. Storms won't occur within three days of each other.
