“Olympia’s total November precipitation will fall just short of the record books. As of midnight Thursday, 19.67 inches of rain had fallen at Olympia Regional Airport in November. That was just short of Olympia’s record for monthly precipitation – at least going back to 1948, when weather observations began being measured there, said National Weather Service meteorologist Johnny Burg. The wettest month that has been recorded at Olympia Airport was in January 1953, when there were 19.84 inches of precipitation,” quoting The Olympian.
However, Seattle did record the wettest month in history:
“By 9:30 p.m. [Wed. Nov. 29] precipitation had broken the one-month record for Seattle, 15.33 inches set in December 1933, when the official reporting station was at the old downtown Federal Building. By about 10 p.m., the November precipitation total at the current station, Seattle-Tacoma International Airport, stood at 15.45 inches, National Weather Service meteorologist Doug McDonnal said. The rain total climbed to 15.63 inches by early Thursday morning. Earlier, the weather service reported a record low of 18 degrees at the airport, breaking the old mark for Nov. 29 of 22 degrees set in 1985. Other record lows included 12 degrees at Bellingham, near the Canadian border; 25 degrees in Hoquiam near the coast, and 2 degrees below zero at Pullman in the southeast corner of the state,” quoting KOMO TV4.
