Earlier this week there was a tornado watch in the area. Some people apparently saw the beginnings of funnel clouds about 5 miles from where I work. I happened to be in the middle of the building on the top (8th) floor working , so I didn't notice anything, but a bunch of people around the edges witnessed a very sudden and quite massive amount of rain. So much that they couldn't see the building across the parking lot. Another few people had taken the elevator down to the ground lobby floor. As they exited the elevator, a massive wind slightly turned the revolving door at the front of the lobby in such a way that the outside air was sealed from the inside air. As a result of the massive pressure difference and wind force, the glass from the revolving door exploded. I know a few people that ended up with glass shards on their body and in their hair. No injuries though.
