Sure, it rained yesterday, and sure, it rained pretty hard in some spots. Boeing Field, after all, saw .18 inches from a midday thunderstorm, and heavy showers pounded areas north of Everett as a strong line of storms—including a waterspout by Whidbey Island—moved through.
Compared to what fell from the sky nine years earlier, however, yesterday’s downpours were mere sprinkles.
Torrential rains swept through Seattle on Oct. 20, 2003, making for the wettest day in the city’s history. 5.02 inches of rain was measured in the gauge at Sea-Tac Airport, shattering the previous daily rainfall record of 3.41 inches from Nov. 20, 1959. The mark for the most rainfall in a 24-hour period was also easily broken, with the 3.74 inches that fell from Oct. 5-6, 1981 well over an inch shy of the October ‘03 deluge.
