With the potentially severe storms on Sunday, are there recommendations for the eggs/incubator if the power goes out? Are their precautions we can take, especially if we're not home?

Hopefully, the power did not go out. If the power goes out just try to keep the incubator warm by covering it. But if not home, that would not work. So, the power going out can hurt the hatch. If it is just for a few hours, that would not be a big problem.
