WASHINGTON -- The National Park Service says its low-lying monuments and memorials along the National Mall came through superstorm Sandy largely unscathed.

Spokeswoman Carol Johnson says there's a slight possibility that the World War II Memorial could have some minor flooding, but it's designed to withstand it and would not be damaged.

The Potomac River has been forecast to crest at around 9 feet early Thursday morning in Georgetown. Johnson says the Mall's flood-protection system can protect it from crests of 17 feet or higher.

Johnson says there was some minor flooding on Hains Point, the tip of a manmade island that includes a park and a golf course. The park was closed Tuesday.
