Handling four day freeze in Central Texas, with power outages

So I have an in-ground pool, that has freeze protection. My plan was to keep it running based on this protection throughout the freeze. But my power has been out 36 out of the last 48 hours and now with the worst part of the storm coming in, i am thinking of contingencies
I plan to
1. Release Filter pressure
2. Drain Filter by opening filter plug
3. Drain my pumps by opening the drain plugs
4. Obviously turn off the breaker (Step 0)

Is this good enough ? anything else i should be doing...
