Power outages & BM in freezer

DottyBlue

We are supposed to get slammed tonight and tomorrow with some pretty intense thunderstorms and high winds.  I am fully expecting to lose power, but am hoping it won't be for long.

I have a TON of BM in our freezer.  it's all in the center, so well protected by other frozen items.  Does anyone have insight on how long a freezer (above fridge) will keep breastmilk frozen in a power outage?
