I'm more of a "better safe the sorry" kind of person. Especially when it comes to flooding.
I was thinking in terms of last minute preparations.
I'd rather risk humidity in a bag then having my basses submerged in toxic/rancid water. If you can scrounge some silica gel packets that would help, but for the most part people don't have those laying around the house.
As for relying on leaving your basses up somewhere high in their cases alone,
Most people don't realize that when flood waters get into your house that everything starts moving regardless if the water is moving at a fast rate or not. Rising flood waters even at a slow rate will send your furniture floating in all different directions. Huge pieces of furniture will knock things over, then you will find pieces to a chess set left exactly where you saw them last on top of a coffee table that has moved ten feet across the room...weird stuff like that. There is no way to predict what will happen exactly. Anyone that has been through massive flooding will know exactly what I mean.
Then there are the odors that get into everything, especially wood. I'm not just talking about mold and mildew, that happens after the waters recede. I'm talking about feces from the sewars that back up through your toilets as the water rises, oil, chemicals, rotting animals, etc.
That's exactly why you want to put all of your valuable in sealed plastic bags.
