If you read the article, it's Wilkes-Barre and surrounding areas of Luzerne County, which do in fact have 200,000 people.
On another board there's an unsourced RUMOR (and I stress RUMOR that the reason for the evacs despite the crest being below the top of the levees is there's a bubble in one of the levees.
I suspect that since Katrina there's just much less confidence in levees.
Let's pray that RUMOR is false!
What do you mean by "bubble" ?
