A time line of events and the status of the Virginia Tech campus and community can be found (and are being regularly updated) here and here. Locally, a 8pm vigil remembering the fallen will be held tonight on the campus of North Carolina State University, Raleigh. In Chapel Hill, the University of North Carolina will be holding a vigil at the same time in The Pit by the Student Union. Additionally, there is an online vigil from The Virginian-Pilot (which allows for comments and condolences) here.
UPDATE: It is with great sadness that I report that a former employee of UNC at Chapel Hill was one of the 33 victims from yesterday's tragedy. Christopher James Bishop (aka Jamie Bishop) was gunned down yesterday in Norris Hall as he was teaching an Introductory German class there. Some of Bishop's students have been hailed as heroes for blocking the door and preventing gunman Cho Seung-Hui from re-entering the classroom after his first horrific invasion...very few survived unharmed. Bishop's widow, Stefanie Hofer, also moved with him from UNC-CH to Virginia Tech in 2005. She is also an instructor in German at Virginia Tech. The News & Observer has a profile of Mr. Bishop here.
This just continues to be a horrible, tragic, and incomprehensible loss.
