I was on Carrigain (next door) on Friday and the whole area is getting pretty lush. The major deciduous trees still have a lot of filling out to do, but there's lots of vegetation on the bloom.
Streams on Carrigain were surprisingly manageable; not low (by any means), but not impassable. The trail itself had evidence of the recent rains, but were surface-dry and plenty firm enough.
There was a ribbon of ice and rotten snow on the trail above Signal Ridge; none was evident anywhere else short of Washington's shoulders (and maybe a bit on Lafayette).
If I remember the Hancocks, it's WAY boggy down low. I'd guess you knew this, but maybe the data on Carrigain is helpful.
