The mood in downtown Seattle was electrifying, as the parade featuring the Super Bowl champions got underway Wednesday near the Space Needle.
Revelers packed the 2-mile route. They wore blue and green wigs, waved flags, scarves and signs, and erupted into spontaneous song and dance.
The Washington National Guard is escorting many of the players in Humvees and other military vehicles.
The parade is heading to CenturyLink Field, where a ceremony will mark the team's first Lombardi Trophy in 38 seasons.
The cheers are likely to get more boisterous as fans observe a "moment of loudness" at 12:12 p.m.
