Under tenth percentile is never good:
That's where Big Cypress Nat'l Preserve ranks this year, looking back from 1970 to present, in terms of total dry season rainfall accumulation.
Five of the last ten dry seasons have scored under 25 percent. Over the same period, only dry season (Nov 2009 - Apr 2010) has been truly wet. Compare that to the wetter 1990s period where we had four "wet" dry seasons, i.e. above the 75th percentile, and only one marginally "dry" dry season (Nov 1995 - Apr 1996).
Sometimes the decades creep up on you like that.
