Hurricane Irma approached Florida as a terrifying storm — by some measures the strongest ever to leave the Atlantic Ocean. It flattened Caribbean islands, devastated the Florida Keys and caused the largest evacuation in Florida's history.

It did far less damage than feared. With hundreds of lives and billions in property on the line, the way atmospheric forces nudged the storm just a few miles made all the difference.
