This comment has more to do with the heat and humidity, I wonder if before entering an ice environment, flooding and large amounts of water is something that is before or in the middle of entering a full cold era.
Sharing something that could be useful for some who live in places with high humidity or could find themselves in a similar situation.
My family and I have been dealing with toxic mold exposure for the past year in East Central Florida, and we have been living between hotels and rental houses for a short period because the house we lived in still contains mycotoxins that we cannot locate yet to repair.
What I would like to share a few notes that might be helpful for some.
-It is preferable re-wash winter clothes or any type of fabric put them in boxes or sealed plastic bags so that they do not absorb humidity, because that moisture may contain mold spores. That is, clothing that you do not wear frequently should not be left exposed to the open environment inside your home. I am located in the United States and most homes have central air conditioning, a high percentage of which can be contaminated with mold if there is no proper maintenance.
That's why sometimes clothes that smell like wet socks can be mold, and can make you sick, Even in certain population it can cause serious respiratory problems and even arrhythmia.
-Plastic boxes with the essentials, some for clothes, food, others for basic kitchen utensils, another for supplements and medicines, etc., greatly facilitate order and easy transport.
-Lots of plastic zip lock bags, to maintain hygiene and order, too.
-It is very useful to have an indoor air quality meter.
-Keep it basic, useful, and easy to get out of in case you have to leave quickly or evacuate the area.
-In this last year dealing with this personal situation has made me reflect a lot that in emergency situations you have to let go of the attachment to material things, and look to what is important first, your safety, health and your family, physical and spiritual integrity.
-Keep in mind where the rivers of your area flow, to evacuate in time, to make your own decisions.
I found this video which I don't consider to be totally correct, although it gives an idea if the sea level rises considerably.
