The Columbus Day parade will step off at Sunday at noon in Huntington Village.
Among the parade participants will be more than 25 chapters of the Sons of Italy and seven school bands.
The grand marshals will be Joan Rondinelli, first lady of the New York State Order of the Sons of Italy in America and radio personalities Don K. Reed, Paul Richards and Joe Satta.
The parade will move along Main Street from Park Avenue to the Christopher Columbus statue.
In an annual tradition, town officials laid a wreath Friday but the ceremony was moved from its usual place by the statue to town hall because of concerns about the weather.
Participating in that ceremony were Town Supervisor Frank Petrone and Council Members Susan A. Berland, Mark Mayoka and Eugene Cook, as well as Joseph Rondinelli, state chair of the Order of the Sons of Italy in America, which runs the parade; Keith Wilson, parade committee chair; and other members of the parade committee.
Suffolk police issued an advisory Friday about street closings during the parade.
