Extreme precipitation fell over the mountains of NC in January, while central and eastern parts of the state were much drier. Areal average precipitation for the 2 mountain climate divisions in January was 10.59 inches, ranking January 2013 as the wettest on record for that region.

The wettest January (statewide average) was in 1998 with a statewide average of 7.9 inches. (Jan 1998 was also the 2nd wettest for the mountains, after 2013). The driest January on record was in 1907 with 0.71 inches.

With heavy rain in January came many reports of flooding in the valleys of western NC. January also brought reports of wind damage across the state, and our first taste of frozen precipitation with snow, sleet, and freezing rain reports from most every region.
