As Hurricane Sandy makes its way toward the eastern seaboard of the United States, disaster experts and meteorologists warn that the mid-Atlantic and Northeastern states face dangerous winds and heavy rains that could trigger flooding in the coming days. Some forecasters even say that Sandy has the potential to be a multibillion dollar disaster greater than last year’s Hurricane Irene, though it may be too soon to tell if it has the power and trajectory to fulfill that worst-case scenario.
