Wired: ” You never know when you’re going to have to bug out on short notice. The politics of the moment are less than predictable. Disasters never strike on schedule, and few stores stay open for a hurricane or an insurrection. That’s why it’s important to make plans well in advance and put together gear for an emergency kit, say experts on disaster preparedness—and to stock up on the essentials that can keep your family healthy and safe in the event of hurricane, flood, earthquake, wildfire, or all-too-human failures. But not every disaster is the same. There are two main scenarios you should keep your family prepared for, says Jonathan Sury, a senior staff associate at Columbia University’s National Center for Disaster Preparedness. In some cases, you may have to jump into a car with a go bag, or a bug-out bag, outfitted with the barest essentials, such as a three-day supply of water, purification tablets or water filters, a good flashlight, and batteries. In others, you may be left sheltering in place, possibly without tap water or access to the power grid—and in serious need of a good power bank or two. Here’s how to prepare for a shorter-term emergency—and what to stock up on in advance. This isn’t a survival guide to civil war or the apocalypse, of course. But the advice and gear here should help you and your family safely weather a natural disaster such as a storm, a flood, an earthquake, or a wildfire–not to mention a systemic failure in your water system or power grid…”
