Low-lying monuments like the MLK Memorial and the Jefferson Memorial are expected to take on water later on Tuesday when the Potomac reaches historic flood levels. The river may exceed previous record flood levels from melting snow in 1996. Flooding as a result of Hurricane Sandy will affect most of the east coast.
The floods could be the worst for the DC region in 16 years. The National Park Service is monitoring low areas along the Potomac as the storm progresses.
