Can you give me some more details? For example, there is storm during rain, but I’m assuming that is not what you meant.
The storm will have winds that can blow insects and animals out of trees before they can get into their caves. The storm can occur in many different weather conditions such as clouds, nighttime, heavy rain. The storm can cause floods and wash away some sea creatures, and it has extremely strong winds. When the character moves without being in a house, there will be different H-scenes when entering each area. You can add dryococelus australis insects on the cliff when climbing to dig for minerals, and they can also be washed away by the storm.
