Dry and then store in sealed container with silica gel. Silica will maintain dryness, but will not dry filament by itself.
Also, containers must have a seal of some kind. Regular plastic tubs will let some moisture in. For a few days or a couple of weeks that’ll be fine, but over a month they’ll let moisture in. Get vacuum bags.
There are pretty cheap reusable vacuum bags that use a little pump. I use a cheap kitchen vacuum machine, and regular food storage vacuum bags.

Your best hope for storage is it not getting much wetter, ziploc bags with silica are fine, a tub is easier to paw through and grab what you need quickly.
A drier will actually refresh a roll and get it printing close to new again. Look for excess stringing for the early signs, and the filament bubbling and/or popping as it comes out of the nozzle for extreme signs of wetness.
I’m in a fairly dry environment, I’ll happily leave a roll on the printer for a week without adverse effects. But always store an opened roll off the printer in the tub. 3d printer filament storage
