When to Leave: Building an Evacuation Plan Before You Need One

Evacuation goes wrong in two directions. People leave too late, after the roads are full and the decision has been made for them, or they leave in a panic and arrive somewhere safe without their medication, their documents, or their dog's carrier. Both failures come from the same root: the decision and the packing were improvised at the moment of highest stress.

Fix the decision first. Write down the conditions under which you would leave, before anything is happening. Reasonable triggers: an official evacuation order, obviously, but also an evacuation warning for your zone if anyone in the household is slow to move, a fire on the wrong side of a ridge with wind blowing toward you, water rising past a landmark you chose in advance, an indoor temperature during a long outage that you are not willing to sleep in, or a medical device you can no longer power. The point of writing them down is that you will be tired and arguing when they arrive, and a decision made in advance is easier to act on than one made in the moment.

Then build the packing list in three tiers, because how much time you get is the one thing you do not control. The fifteen-minute list is people, pets, medication, phones and chargers, wallet and keys, and the documents pouch. That is it, and everything on it should live somewhere you can grab it without searching. The one-hour list adds the go bags, a cooler of food, water, laptops, and a change of clothes each. The six-hour list adds the things you would grieve: photo albums, hard drives, heirlooms, the contents of the safe. Print the tiers and tape them inside a cupboard door.

Documents deserve their own treatment. Keep a physical folder with identification, birth certificates, passports, insurance policies, deeds, and prescriptions, and keep scanned copies in cloud storage that you can reach from a phone. The folder goes in the fifteen-minute tier. The scans are what save you if the folder does not make it.

Plan at least two routes out, and know the second one properly. The main highway is where everyone else will be, and traffic lights do not work in an outage, which turns every major intersection into a slow four-way stop. Look at a paper map, not just a navigation app, because the app depends on a network that may be congested or down. Keep a printed map in the car with your routes and both meeting points marked.

Keep the car ready, which mostly means fuel. Gas pumps need electricity, so the station is often useless precisely when you need it. The habit that solves this is refilling at half a tank rather than at the warning light, and topping up whenever a storm is in the forecast rather than after it arrives. An electric car needs the same discipline in reverse: charge it when the forecast turns, not when the power is already out.

Pets and livestock need deciding in advance too. Many emergency shelters cannot accept animals, so know which hotels on your route allow them, or which friend or boarding facility outside the area would take them. Carriers, leashes, food, and vaccination records belong with the go bags, not in a cupboard you will forget.

One rule overrides everything else on the road: do not drive into water. Six inches of moving water can knock an adult off their feet, and a foot of it can float most cars, including large ones. Flooded roads also hide washouts you cannot see. If the road ahead is under water, turn around and take the other route you planned for exactly this reason.

Finally, tell someone. Text your out-of-area contact when you leave, where you are going, and which route you took, and again when you arrive. If you are heading somewhere without reliable cell coverage, a satellite messenger does the same job where a phone cannot. Evacuating is not the dangerous part; being unaccounted for is.
