Getting an inch and a half of rain in November isn't too unusual, but in September? It's record breaking.
Seattle recorded 1.71" of rain on Saturday, not only nearly doubling the daily rainfall record of 0.83" but setting an all-time record for wettest September day in Sea-Tac history, which goes back to 1948.
The old record was 1.65" set twice on Sept. 22, 1978 and Sept. 30, 1953.
Rainfall totals were even more impressive further south and west where 2.5" of rain was reported in parts of Pierce and southern King County and nearly 3 inches fell in Olympia.
Perhaps most impressively, a spotter near Potlatch in Mason County reported an estimated 7 inches of rain -- an estimate because that's all the gauge could hold and it overflowed.
Here is a chart of rainfall totals from 7 am Saturday to 7am Sunday, courtesy of the CoCoRahs volunteer network:
And here are some other rain reports from National Weather Service spotter reports:
Grand Mound: 3.58"
Federal Way: 2.48"
For the entire month, Seattle is now sitting at 4.80 inches through Sunday morning, currently tied for 3rd wettest on record:
1) 5.95 - 1978
2) 5.57 - 1969
3) 4.80 - 2010
3) 4.80 - 2010
We'll easily get into 3rd by itself Sunday with eyes on No. 2 by the end of the day.
