Hurricane Agnes Anniversary

The picture at right looks like New Orleans after Hurricane Katrina, but it was Elkridge, Maryland 40 years ago, after Hurricane Agnes.

Agnes did tremendous damage to the Mid-Atlantic, even though it had weakened to a tropical storm by then. At the time, it was the most costly storm ever, doing over $11 billion in damage (in 2011 dollars). It also killed 128 people.

In Florida, Agnes spawned 28 tornadoes. In DC, it flooded the National Zoo, and the Potomac River rose 15½ feet next to Georgetown. It also caused the greatest flooding ever recorded in Maryland, with bridges washed out in Laurel, and Ellicott City under as much as 14½ feet of water. The entire state of Pennsylvania was declared a disaster area.

A slideshow is after the jump.
