Hear the roar and rumble? That’s the return of the big Seafair weekend with air shows and hydro races. Here’s what you need to know about the big events and traffic, plus some fun:

· Blue Angels, hydroplanes and more: Seafair Weekend Festival and other fun around Seattle

· Watch our reporter Vonnai Phair go 400 mph in a Blue Angels jet | Video

· The Blue Angels are back with a larger jet. See how it compares to other planes.

· WSDOT changes I-5 roadwork detours for Seafair, sports events

The Blue Angels are expected to perform at 3:05 p.m. Friday, Saturday and Sunday (subject to change). Other planes will be ripping through the skies of Seattle earlier in the day as part of Seafair.

The Navy’s flight demonstration squadron is known for its tight formations — the planes are as close as 18 inches in one maneuver. Here’s what we learned in 2018. Watch: What to look for in the Blue Angels’ Diamond 360 maneuver.
