The Ksu Foundation's Web Page with information on how you can help. They also have a media presentation and links to other stories about the June 11th tornado.
I have yet to see a specific page for the RED CROSS here in town, but I'm sure they are accepting donations as well.
Please also remember the Flint Hills Breadbasket which helps feed people in need in the Riley County area.
The Manhattan Mercury has a SPECIAL REPORT with more photos and will update as news becomes available.
The tornado was classified as an EF4, the second most powerful classification.
