1) Accuse people selling water or fuel in storm-hit areas of price gouging. Many of the folks who take on the risk of heading into an unstable area do so because they are driven by the twin motivations of fellow-feeling and greed. These people are often the fastest and most effective at getting supplies where they are most needed, because that's also where they can get the best price. This is just as true for Walmart as it is for the guy who fills his pickup with Poland Spring and batteries. Don't use the bully pulpit to vilify disaster entrepreneurs, small or large.

2) Establish a central command for volunteers. One of the tragic lessons of Hurricane Katrina was that by trying to control who gets into a storm zone to help, governments can wind up blockading good people who could do good while waiting for approval from Washington in a situation where communications are often bad. Ordinary people see and know things about what their friends and neighbors need and want that FEMA simply can't be expected to figure out.

3) Fearmonger about civic breakdown and looting. After storms, Americans are typically cooperative and law-abiding. Unfounded fear of looting makes people stay in their homes when they are in danger, return too quickly after the storm passes, and regard each other with distrust at a moment when solidarity is most needed. And there's corollary to this one:

3a) Confiscate guns. Emergency workers and law enforcement shouldn't waste post-storm effort rooting around in people's homes for firearms. Law-abiding gun owners do not, by and large, turn into characters from Grand Theft Auto when they get wet.

4) Throttle entry and exit from the storm zone by keeping immigration checkpoints open. Nothing is classier than having the Border Patrol asking people who have just lost everything—including their important papers—for their papers, please.

5) Insist on managing housing for the displaced. After storms, Americans look for ways to reach out and help. Many would open their homes to people who need a place to stay. Private charities can help broker these placements, as they do now for international refugees.

6) Let bureaucracy stand in the way of communities rebuilding on their own. After a storm, getting schools and hospitals up and running requires speed. That means waiving bureaucratic requirements. Requiring citizens to push paper in order to get their communities functioning again is wasteful even in non-crisis situations, but can be especially painful for cities whose infrastructure has washed away.

7) Increase funding for the federal flood insurance program. When it comes time to rebuild, everyone will studiously avoid discussing the fact that maybe we shouldn't be using a massive federal insurance program to incentivize building in areas that are repeatedly hit by storms. There's a reason private insurers don't offer policies to many coastal dwellers, and it ain't "market failure." (This seems ungenerous to say in the moment when people are facing the loss of their homes and businesses, but it'll be even harder to say or hear after the storm hits.)
