The instinct in the first few minutes of a warning is usually to gather more information. That's reasonable, but only briefly — in most real evacuations, people who moved early, before the situation was completely confirmed, fared better than those who waited for certainty.
Step one: verify, quickly
Confirm the warning through an official source — local authorities, national weather or emergency service, or a verified alert app — before acting on anything unconfirmed. This takes a minute or two, not an hour. Misinformation spreads fast in the early stages of any emergency, so a quick check is worth it, but don't let it become an excuse to delay.
Step two: grab your bag, don't start packing
If you've prepared a 72-hour kit, this is the moment it earns its keep. Grab it and go. The most common mistake in real evacuations is stopping to pack "just a few more things" — that's exactly the delay that turns a manageable evacuation into a dangerous one. The bag exists precisely so you don't have to make decisions in the moment.
Step three: follow official instructions over your own read of the situation
If you're told to evacuate, evacuate — don't wait to see how bad it actually gets. If you're told to shelter in place (a standfast), stay put rather than trying to move through worsening conditions. Both instructions can feel counterintuitive in the moment; both are based on information you don't have access to.
Step four: go early if you're evacuating
If evacuation is advised or ordered, moving early — before roads are congested and before the situation is unambiguous — is consistently safer than waiting. By the time a situation is completely clear, evacuation routes are often already compromised.
Step five: communicate, but do it efficiently
Once you're safe, a short message to the people who need to know — "safe, heading to [location]" — does two things: it takes you off anyone's worry list, and it gives them a data point if things change. Text rather than call where possible; networks tend to jam for voice calls before they do for messages.
The pattern that actually matters
None of this requires special training. It requires having decided, in advance, what your kit contains and where your family will meet — so that when a warning comes, you're executing a plan rather than improvising one under pressure. That's the entire purpose of preparing before you need it.
