It's still unclear whether Sandy will be a devastating storm or just a bad one.
It is clear, however, that Sandy will be remembered as the storm that broke all the rules and baffled the nation's top weather forecasters.
Early Saturday morning, the National Weather Service downgraded the storm from a hurricane to a tropical storm — only to return it to hurricane status a few hours later. Either way, forecasters warn, "widespread impacts" are expected along the coast.
