WESTPORT — The threat of stormy weather Saturday, as cooler weather pushes aside the current heat wave, has caused the “Slice of Saugatuck” festival to be postponed until Sept. 30.

The event, initially scheduled tomorrow (Saturday, Sept. 5), has been rescheduled from 2 to 5 p.m. Saturday, Sept. 30, at the same location, according to the Westport-Weston Chamber of Commerce.

With Saturday’s unsettled weather outlook, as well as consultations local emergency-services officials, “the risk and threat of thunderstorms during the event was too clear to run the festival tomorrow,” Matthew Mandell, the chamber’s executive director, said in a statement Friday morning.

“The large footprint of the event, coupled with how many exposed vendors, bands and residents at the festival, means considering safety beyond just hoping people don’t get wet,” the statement adds.

The date of Sept. 30 was selected to avoid overlapping with Rosh Hashanah and LobsterFest in the coming weeks, Mandell said.

The rescheduled Slice of Saugatuck will feature attractions announced for the initial date, and will take place in the area bracketed by Railroad Place, Riverside Avenue and Saugatuck Avenue.

The event, in its 11th year, celebrates the neighborhood’s cuisine and commerce. More than 40 area restaurants and businesses, organized by the chamber, are scheduled to participate.

There also will be live musical performances, beer and wine gardens, and attractions for children.
