Seafair is returning Aug. 5-7 and will feature a weekend full of festivities, including the unlimited hydro races and U.S. Navy Blue Angels air shows.

Thousands of attendees are expected to pack the areas along the Lake Washington shoreline, including Mercer Island. Great locations to enjoy the event locally include Aubrey Davis Park, Groveland Beach Park, and areas along the north end of the island. Early arrival is key to finding parking and the city asks people to watch for pedestrian traffic.

Here’s some vital information from city:

* The Interstate 90 bridge will not be closed this year.

* Parks will be crowded and parking will be limited. Arrive early and be patient.

* Roads will be congested and traffic control may be directing vehicles down alternate routes. Drive carefully and allow extra time to get home after the shows.

* Proctor Landing will be closed to the public to allow for first-responder use.

* Air shows are loud and noise is sporadic. Consider keeping pets inside during air show practices and performances to prevent runaway pets.

* Boaters should be mindful of no-wake zones and restricted boat traffic areas during the event.

* Mercer Island Marine Patrol will be on the lake along with additional vessels from surrounding law enforcement agencies to ensure everyone’s safety in the water and along the coastlines. Call 911 to report emergencies or safety concerns.

* Sober boating enforcements will be in effect throughout Lake Washington. Don’t drink and operate a vessel.
