Northeast Flooding: 14 Dead, 45 Trillion Gallons of Rain

Sept. 9, 2011— -- The rains and flooding caused by the remnants of Tropical Storm Lee have led to the evacuation of more than 100,000 people in the Northeast and dumped enough rain to fill Dallas Cowboys Stadium more than 50,000 times.

Lee and its aftermath have been attributed to at least 14 deaths. Virginia's governor declared a state of emergency today after flooding submerged parts of the I-95 corridor and left people stranded in their cars. President Obama declared a state of emergency in New York and Pennsylvania.

The National Oceanic and Atmospheric Administration estimated that 45 trillion gallons of rain fell on the United States in the wake of Lee. That's enough rain fill the NFL's largest enclosed stadium, the Dallas Cowboys Stadium, 57, 842 times.

The Susquehanna River in Pennsylvania is finally receding, but officials worry about the integrity of its levees and urge evacuated residents not to return to their homes.

The river reached its highest level ever Thursday night, overwhelming flood gauges. Officials revised their estimate of the river's crest at Wilkes-Barre, Pa., to 42.66 feet today, nearly four feet higher than first thought. Officials warn that's "well beyond the design" of the levee system.

"We are in a precarious situation," said Jim Brozena, executive director of the Luzerne County Flood Protection Authority. "We need people who are ordered to evacuate to adhere to those orders, to stay out of affected areas so that we can [get] things done and hopefully prevail against the river."

At least 75,000 people around the Susquehanna River are under a mandatory evacuation. Communities not protected by the levees have seen hundreds of homes and buildings damaged.

This afternoon, the National Guard used a boat to rescue 11 people, including two children, who were trapped on the second floor of a home in West Pittston, Pa.

The devastation in the region recalls Hurricane Agnes, which ripped through the mid-Atlantic in June of 1972, killing more than 100 and causing significant flooding, the brunt of which was felt in Wilkes-Barre.

A persistent area of low pressure associated with Lee's remnants will remain over the area throughout the weekend, according to the National Weather Service. It is expected that the area will see an additional four to seven inches of rainfall in the coming days.
