At the turn of the 20th century, Galveston, Texas was a bustling city, transformed from a sand bar to a wealthy port town. Today we know how vulnerable the small island in the gulf is to storms, but in the summer of 1900, hurricanes were far from the minds of its residents. As “Today” weather anchor Al Roker says in his new book, “The Storm of the Century,” the ability to predict hurricanes was still in its infancy. When a hurricane landed in Galveston in early September, the city was completely unprepared, leading to the most deadly natural disaster in the country’s history. Al Roker joins Diane to talk about the great gulf hurricane of 1900.
