Seattle, WA broke its single day rainfall record yesterday. The city received 1.20″ of rain on Wednesday, October 18th, 2017, which surpassed the previous record of 1.19″ that was set in 1958. This isn’t a small feat due to the fact that the city roughly 150 days of rain each year.
At 12 AM PDT, Seattle has surpassed the daily record with 1.20" of rain. The previous record was 1.19" set in 1958. #wawx
The previous record was only surpassed by 0.01″. If the temperatures were below freezing, this precipitation would have accumulated to 1-2 feet of snow, depending on the density. The forecast is calling for more rain the next few days, which could lead to minor flooding in the area.

According to a different source, the greatest single day rainfall total for Seattle was 5.02 inches set on October 20th, 2003. I remember the day well because I biked to all my classes at the UW and wished I had a kayak instead. http://www.seattleweatherblog.com/rain-stats/
This article is a little misleading. Seattle broke its daily record for the date October 18th, not the all time daily rainfall, which was October 20th, 2003 @ 5.02″.
