I'd try to take a cellphone video of every room in the house, opening closets and drawers as you go. Move at a deliberate pace; you will need to review the video and write down what you see in it should the house burn down, and sweeping too quickly through will make that difficult.

A 32GB thumb drive with scanned copies of your important documents is a nice-to-have if you can swing it.

I would only try to grab medications, three day's clothing, then irreplaceable items first, followed by what you have room/time for. If you have firearms, they are likely only covered up to $2,500 on a basic homeowner policy. Please be sure any left behind are unloaded, the heat will cause them to discharge otherwise.

Anything that is essential to earning your living (tools, laptops, photography equipment, etc.) is high priority.
