Here is a look at some of the stories that CNN plans to follow this week:

Millions threatened by possible flooding from Sandy

Flooding is a major concern as Hurricane Sandy churns toward the U.S. East Coast. While strong winds are likely to bring major power outages and other troubles to inland areas this week, the possibility of significant storm surge has officials particularly concerned about millions of people on mid-Atlantic, New York and New England coasts, especially in New York City.

The center of the storm on Sunday afternoon was a Category 1, with max sustained winds of 75 mph and was a couple hundred miles off North Carolina. It could hit anywhere from Maryland to New York late Monday or early Tuesday, the National Hurricane Center says. It could unite with a low-pressure system from the West before it hits land, which could make it a little stronger.

Four to 12 inches of rain are possible over parts of the mid-Atlantic states, and 1 to 5 inches are possible in southern New York and southern New England. But storm surges also could be a problem; if peak storm surges happen with high tide, floodwaters of more than 6 feet are possible in the New York City area, the hurricane center says.

People in parts of New York City are under mandatory evacuation orders, and the city's train service will stop Sunday at 7 p.m. in advance of the storm. Check out what other areas of the East Coast are doing to prepare.

Tricky final campaign week for Obama, Romney

Hurricane Sandy isn't going to make the last full week of campaigning any easier for President Barack Obama and his Republican challenger, Mitt Romney.

Both presidential candidates have canceled campaign events in the coming days because the East Coast is preparing for the storm. Obama even canceled a Tuesday event in Colorado - far from Sandy - so he can stay at the White House to monitor any disaster-related developments.

Man who plotted model-airplane attack on Pentagon faces prison term

A man accused of plotting to use model airplanes loaded with explosives to attack the Pentagon and U.S. Capitol is expected to be sentenced in federal court Thursday.

Rezwan Ferdaus of Massachusetts pleaded guilty to plotting the attack and attempting to support al Qaeda for attacks on U.S. troops overseas.

Ferdaus planned to use large, remote-controlled model aircraft filled with C-4 plastic explosive against the targets, officials said. He was arrested last year as a result of an undercover FBI investigation.

Michelangelo's Sistine Chapel ceiling anniversary

Thursday marks the 500th anniversary of the unveiling of Michelangelo's remarkable fresco on the ceiling of the Sistine Chapel in the Vatican. The work, which took the artist four years to create, was first seen when Pope Julius II celebrated All Saints' Day Mass on November 1, 1512. The ceiling was part of a complete renovation necessitated by structural problems that caused cracks in the previous painting, according to the Vatican website.
