For those of us who live inland, hurricane-tracking seems more a curious indulgence, but if you live along the coastal regions in a hurricane zone, keeping tabs on these atmospheric leviathans is paramount. Case in point, Hurricane Isaac — at one stage threatening Florida and the Republican National Convention — has moved well west, now following a path through the Gulf reminiscent of the one Hurricane Katrina traveled seven years ago. While it’s shaping up to be a weaker Category One storm when it makes landfall, with sustained winds of between 74 and 95 miles per hour, it’s still very much a hurricane, prompting the governors of Alabama, Louisiana and Mississippi to declare emergencies (and in Alabama’s case, the governor to order mandatory coastal evacuations).
