February 2014 Precipitation Summary

Posted: March 3rd, 2014

After four straight months of drier than normal conditions, Seattle finally got wet. Seatac recorded 6.11″ of rainfall, well above the 30-year normal (3.50″). Most of Western Washington hovered around 125% with the curious exception of the likely rain-shadowed Snoqualmie and Snohomish Valleys.

 

The greatest 24-hour rainfall total of the month occurred on the 16th when 1.52 inches fell. That turned out to be the only day with rainfall greater than an inch. There were 6 days with with greater than 0.50″, 14 days above 0.10″, and 19 above 0.01″. Neither “heavy rain” nor “rain” were officially reported, which seems odd, but “light rain” fell on 18 days.

 

While Seatac may or may not have avoided heavy rainfall, the city endured its most significant (widespread) event in over 5 months. Parts of South Seattle, especially along the banks of the Duwamish, came close to a 10-year, 6-hour event when an atmospheric river and cold front passed through late on the 16th.
