Got one reply for people looking into it. From my research, at this time they are 60% sure it will come within 17,000 feet of earth. They are using the 1-10 point score and are currently at a 6. Closer to the event, the percentage of surety will rise. I notice that they removed this web page today that mentioned they were 60% sure of where it would pass and now are saying the odds are one in 100,000 that it will hit earth. My guess is they are backtracking to avoid any panic. Even if it hits, according to Impact Earth (http://www.purdue.edu/impactearth/), if the asteroid does hit on land, anything within 10 miles of impact will be destroyed but it would not stir up dust and cause climate change or change the earth's tilt or rotation. When entering its estimated size (60 meters) and speed (About 13 km/s - They don't know the density yet, so I entered iron for worst case scenario) and a low angle into Impact Earth we see that if it hit earth, the area inside 20 miles from impact would be affected, but everyone else would be safe. The crater would be about 3,060 feet in diameter according to Impact Earth. Although this is the real deal and not like the Elenin hoax, I believe that it will be devastating only for those who live within 10 miles of impact.
