Jax area rainfall already above average before September deluge

Even before the extremely wet beginning of September, August in North Florida had marked a return to above-average rainfall across the region, according to numbers released Monday by the St. Johns River Water Management District.

Much of the extra rain was due to the Aug. 5 arrival of Hurricane Debby.
