Journalism on Drugs

I have a good friend who lives in the San Antonio area. Today I did a news search to see how things looked there after Hurricane Dolly swept through the area. I found the article below which recapped the damage done in a very succinct manner, like a good write-up is supposed to do. But then, right at the end they throw the reader a vicious curve ball. And I mean a wicked Roger-Clemens-on-steroids curveball. Have a look for yourselves...

"WHOA!" Right?

FIVE TONS???

Can anybody explain this journalistic twist for me?
