More than 50 million people from the mid-Atlantic to New England braced Saturday for a potentially massive storm, as Hurricane Sandy churned northward on a collision course with another storm system that is sweeping in from the west.

Tens of millions of people in the eastern third of the U.S. in the path of the unprecedented freak storm had hours Sunday to prepare for the first raindrops that were expected later in the day, to be followed over the next few days by sheets of rain, high winds and even heavy snow.

The warning from officials to anyone who might be affected path was simple: Be prepared and get out of the way.

Amtrak began canceling train service Saturday night to parts of the East Coast, including between Washington and New York. Airlines started moving planes out of airports to avoid damage and adding Sunday flights out of New York and Washington in preparation for flight cancellations on Monday.
