$2 billion in damage from Hurricane Isaac? Details from Bloomberg Businessweek below.
"...The fact is, many people lack the resources to escape. Having no money, no mode of transportation and no friends or family in safe places means no choice but to weather the storm." - from an NBC News story on why some people won't (or can't) evacuate to a safe spot before a hurricane.

Hurricane Isaac May Cost Insurers $2 Billion; AIR Says. Details from Bloomberg Businessweek; here's an excerpt: "Isaac, the storm drenching Arkansas after making landfall in Louisiana as a hurricane, may cost insurers as much as $2 billion in the U.S., risk-modeling firm AIR Worldwide said. The industry’s claims costs, including wind and storm-surge damage to residential, commercial and industrial onshore properties, will be at least $700 million, the Boston-based firm said today in an e-mailed statement. The estimates are a fraction of the $41.1 billion cost for Hurricane Katrina, the 2005 storm that struck Louisiana and caused flooding in New Orleans. Hurricane Irene, which lashed the U.S. East Coast last year, cost $4.3 billion."

Tropical Swirl. Yes, those high clouds spreading into southeastern Minnesota are the forerunners of "Isaac", which has lost all tropical characteristics. Rain may spread as far north as Iowa and southern Wisconsin, the best chance of flooding from Missouri into central Illinois. IR satellite image: Naval Research Lab.
Drought-Denting Rains. NOAA HPC shows some 7"+ rains for Illinois, as much as 3" as far east as Pittsburgh, all from the soggy remnants of Isaac.
Flood Potential. NOAA has outlined the greatest potential for flash flooding from St. Louis to Peoria, Champaign/Urbana, Chicago and South Bend, Indiana.

Storm Psychology: Why Do Some People Stay Behind? Great question, and NBC News does a good job providing credible reasons why many people can't (or won't) evacuate to higher ground in advance of a hurricane. Here's an excerpt: "It’s the question so many of us have while watching news coverage of a hurricane or tropical storm like Isaac: Who are these people who don’t leave home even as an angry storm is advancing – and what are they thinking?! The short answer: For some, the up-and-leaving idea isn’t as easy as it sounds to those of us watching from a safe and dry distance. Actually, a 2009 article published in the journal Psychological Science sought to examine the reasons some people won’t evacuate, despite the urging or even mandates of city and state officials, by asking a group who would know: Hurricane Katrina survivors who weathered the storm at home."

My oldest son, lead guitarist for "The Lost Wheels", is a football fanatic. "How can I possibly know how well Andrian Peterson's knee will hold up after Game 4?" Walt asked. I shrugged. Welcome to my world. Some things are not only unpredictable, but unknowable.

"The same human economic activity that has brought freedom and opportunity to billions has also increased the amount of carbon in the atmosphere. While the scope and longterm consequences of this are the subject of ongoing scientific research, common sense dictates that the United States should take measured and reasonable steps today to reduce any impact on the environment. Those steps, if consistent with our global competitiveness will also be good for our national security, our energy independence, and our economy."Photo credit above: "No longer a Republican concern."
