Fueled by a parade of “Pineapple Express” storms, California is in the midst of its wettest water year in 122 years of record-keeping, according to federal scientists. Between October 2016 and February 2017, California averaged 27.81 inches of precipitation, the highest average since such records began being kept in 1895, according to data released Wednesday by the National Centers for Environmental Information, part of the National Oceanic and Atmospheric Administration.
