Environment - Non Weather Related; Procedure; Weather
Crew was nearing the bottom of the Hawks 7 Arrival in to Seattle and had descended to 5;000 ft. per ATC instruction. Shortly after leveling at 5;000 ft.; crew experienced multiple wake turbulence events from a preceding B737. The pilot turned off the autopilot. Roll rates were roughly 15-20 degrees with about 5-10 degrees of bank. We did not deviate from course or have any exceedance. At the time of the event; the pilot flying (Captain) had auto-throttles off for practice.On the STAR; we were made to slow down early due to the close proximity of the airplane ahead of us. And for metering. We also had tailwinds and were only about 5 miles behind the airplane in front of us. We suspect the tailwinds made it take longer for the wake vortices to dissipate leading to our situation. In the future; I will be more vigilant when encountering this type of threat and talk about it with the Captain. If needed; we can ask for a delayed descent or vectors to mitigate this.
