The problem in Pittsburgh is that precipitation levels have been above normal all year, so the ground was already excessively moist even before Frances and Ivan came to town. This is the first time I can remember that every month of the year (so far) has had precipitation levels above the monthly average in Pittsburgh. One meteorologist described the Pittsburgh region as a "wet sponge" that can't take on any more water.

Above is The Weather Channel's "Palmer Drought Index" map. Most of Pennsylvania is shaded in dark green. Meanwhile, other areas affected by Frances and Ivan are shaded either light green or not at all. The ground in these areas is still capable of holding extra water; meanwhile, the ground in most of Pennsylvania is not.
