[QUOTE="WPLG, post: 38292, member: 158"] There’s an old adage in emergency management that our most precious and perishable commodity in any disaster is time. A large part of what makes an emergency an emergency is the limited time available to address the danger at hand. When you’re faced with a medical emergency, it’s both the severity and suddenness of the threat that distinguishes an emergency from a scheduled surgery or procedure. Severe and sudden is a bad mix in the medical field. The same goes for disasters. Hurricanes are, by definition, severe events. The extreme 74 mph or higher winds of a hurricane, usually occurring over hours, not minutes, can inflict serious to catastrophic damage.
