Does Google Index an Alert Div w/Delayed Hide

[WEOMedia]

We have a div at the top of a client's the page that displays an alert to the user. After 30 seconds it is rendered hidden. Does Google index this? Does Google take this into account when it ranks the page?

Run a spider simulator to see what Googlebot sees - it's either seen or not depending on the implementation of the code.
