You could invest is a back up power source. Small gas generators will work for long power outages. For short ones you won't need to worry about it.
Also your in ca so if it's warm if I had to I'd bag everyone up and go outside.
X2. The power goes out in my apartment all time. it's only for about 30 mins at a time though, so when it went out in winter, I put my snake under my shirt with a blanket on top. haha I know this wouldn't work for multiple snakes but it worked for one.
