As a student living near the Mississippi Gulf Coast during Hurricane Katrina, I experienced first hand the incredible power of nature and its ability to grind civilization to a halt. Unfortunately I also witnessed how such damage can be compounded by inadequate planning or coordination from government agencies, insurers, and aid organizations. Six years later, these events were close to mind when the Souris River overran its banks and flooded the city of Minot, North Dakota, where I was stationed. My role as a new Air Force physician taking care of aircrew and nuclear surety morphed into assisting our helicopter squadron assess the damage to critical healthcare infrastructure along with providing medical care/transport to stranded personnel. I discovered that some effects of that disaster, like black mold or depression, might be hidden initially but can far outlast the floodwaters.
