Better than just filling the tub if a hurricane threatens your water supply

[From a post I left on Facebook at 1:54 p.m. on Friday, August 25, 2017:]

If you live somewhere hurricane-prone and don't already have one of these, they're a modest and prudent investment for next time, I highly recommend the WaterBOB. 

It works exactly as you'd think from the photo, and stores 100 gallons without worries about contamination or leakage. It beats the heck out of trying to seal your bathtub drain with Saran Wrap or its regular stopper. At $22.70 from Amazon.com, it's well worthwhile just for your peace of mind. I've given several to relatives and friends, and one is filling one of my bathtubs at this very moment.

UPDATE (Thursday August 31 @ 1:35 a.m.): I reviewed this product in slightly more detail and considerably more drama at Amazon.com: Writing from Houston during Hurricane Harvey: I'd give this product SIX STARS if I could! Brilliant!.
