Seattle’s Seafair Torchlight Parade is returning to the waterfront for a second year with expanded, all-day festivities at Pier 58 and Pier 62, alongside pre-parade events, music, and family activities as crowds flock downtown. City officials warn of busy streets and reroutes while organizers anticipate large turnout and community safety groups, including Chinatown Block Watch, participating in the weekend's events amid new logistical details like parking restrictions for visiting floats.
