It's never a bad idea. Justa is correct about the contaminated ground water in FL after storms.
Most of us are pretty acclimatized to the convenience of plastic bottled water. It keeps a long time, it has no bad taste, and it's in the right size for drinking.
In case of emergencies, I have several of these 5 gallon collapsible jugs. You can buy them on Amazon for $9.99 each.

I also carry these in my home:
Potable Aqua Water Purification Treatment (50 Tablets)
This is a neat idea for emergencies - it allows you to fill your tub with tap water (55 gallons): https://waterbob.com
Those 5-gal. things are very nice. (After losing water several times over the past few years, I’ve decided that I’d much rather lose electricity than water.)
And those foldable carriers take up little space when not in use. I keep a couple around and I don’t live in a hurricane zone.
Those tabs are not a bad idea for “if TSHTF” and supplies run out. How long do the tabs keep?
