SEATTLE — An analysis of Monday’s storm shows northwest parts of the city had “extraordinary” rainfall — as much 1.96 inches in 6 hours.

“It was a pretty big storm for most of the city — lots of rain in a relatively short amount of time,” said Seattle Public Utilities (SPU) meteorologist James Rufo-Hill. “But if you live in Ballard, Crown Hill, Phinney Ridge, Magnolia or Broadview, there was historic rainfall — you really got drenched.”

Rufo-Hill said SPU’s Crown Hill rain gauge recorded 2.62 inches of rain during the 12-hour period and 1.96 inches in the 6 hours from 6:00 a.m. to 12:00 p.m.— which he called “an extraordinary rain event.”

The 12-hour average for the rest of the city was 2.27 inches.

Rufo-Hill’s map-based analysis of the storm, was informed by data from 8 of SPU’s 17 rain gauges, which are distributed throughout the city.
