Just in from the scanner. Metro Tour bus with around 50 passengers on board has crashed off Melrose and is hanging about 10 feet over the lanes of I5 below. Accident involves two buses and there are reports of injuries. Heading out now for coverage and pictures.
Update: 12:52pm - It's actually two big tour buses that made a really poor choice to go down the very steep Thomas towards I-5 and slipped the whole way. The front tires and door of one bus is hanging over the travel lanes of I-5, but it doesn't appear to be in danger of falling. It did a real number on the guardrail and concrete though.
Update: 1:09pm - First pics:


Witness saw 1st bus had hit rail and then saw 2nd race down behind down Thomas
Update 1:15pm: Justin is talking to people at the scene. The buses were full of kids. The first bus went down Thomas and slid into the guardrail. Then the second bus followed the same route and slid "really fast" down the hill, clipped the first bus and pushed it further over the edge, then came to rest beside it. Parents and other friends and family are at the scene looking for their loved ones, but not able to reach them as they're all in triage in a nearby apartment building lobby.
Update 1:20pm: The kids were coming back into the city from a Job Corps event, according to parent Frank Tyson. All injured kids are being taken to Harborview for treatment. Not clear exactly what that number is for now. Family can go there to find them.
Update: 1:23pm: The squiggly lines in the snow here is from the buses sliding towards the cliffs of I-5:
