At the first sign things are getting dicey, fill up every tub, sink, bucket, trash can and other receptacle with water.

Or simply do a yearly refresh of the water in the rack of four 55 gallon food safe barrels in your basement.

"Or simply do a yearly refresh of the water in the rack of four 55 gallon food safe barrels in your basement."

Do both. And keep a couple of plastic 50 gallon trash barrels in the garage to put under the water spout when it rains. In a disaster situation people will be shocked to see how much water they actually go through on a daily/weekly/monthly basis.
