It was quite a storm - the winds would have been head-on to that face. I watched it roll into downtown yesterday - it was very impressive. I'm going to see if I can walk over there and snap a few pics. Here's the release for the DPM from just an hour ago [[had run a shuttle earlier today that went from Times Square to Broadway, no trains near DW building):

MEDIA ADVISORY
PEOPLE MOVER CLOSES TO ALLOW FOR WORK AT THE WHITNEY BUILDING
[[07-12-2011) – DETROIT, Mich. – To allow for the clearing of debris on the upper levels of the David Whitney Building, the Detroit Transportation Corporation has closed the Detroit People Mover this afternoon. The People Mover operated a two-train shuttle service from 6:30 a.m. to 11:45 a.m. this morning.
As a safety precaution, the system is not expected to reopen remainder of the day to allow building management to complete stabilization and removal in proximity of the Grand Circus Park Station and guideway. Station windows required repair as mortar fell from the building as a result of yesterday’s storm.
