We recently evacuated for a week. The fire was a mile away, and coming our way. We had a half an hour to get out.
I grabbed the wife, the 2 dogs, all of my guitars, valuable paperwork, all cash or jewelry, or small valuables, passports, licenses, documents, some clothing, some snack food only, dog food and bowls, some water, all computers, with mouse and keyboard, ALL pictures of friends, family, experiences, and all medications, and a couple flashlights. Cellphones.
All Covid gear. Masks. Wipes. Gloves.
I also took some empty Folgers or Costco plastic cashew containers and put some small plastic trash bags, and a roll of toilet paper in it. Instant port-potty.
If you have some time, start taking pictures or a video quickly of everything inside and outside the house. Be quick about it, and don't forget to take the camera with you. (My wife forgot it due to the fog of war). Insurance will want some type of proof. This is why taking your computers is so important.
Everything else can be repurchased or replaced, in most cases.
Synths can be replaced. Amps too. Most stereo gear as well, even though it hurts. Your favorite guitar, not so much.
Also, consider putting all of your water sprinklers on and saturate the ground and trees all around the house with water right away. Let it run.
Fires are finicky. And do not dally. Find out exactly how long you have.
There is a huge difference between a warning and a mandated immediate evacuation. But, take no chances.
Hope this helps. Stay safe.
