Probably would have been safe to operate the subways until midnight last night.
The FAA site mislead you; ACY has been closed since early this morning ( but no mention of Andrews being closed):

The closure of ACY is listed below the line (in the ADW box), so the FAA shares a lot of the blame for the confusion.
A few other minor airports are closed, but I just saw Weather Channel footage of the PHL airport with plasitc bags placed over all ticket counter computers and kiosks.
