Unseasonably warm weather -- with a forecast high of 58 Fahrenheit (14.4 Celsius) -- is likely to swell crowd sizes at the city's 12th professional sports championship parade since 2001, Mayor Marty Walsh told reporters on Monday. "We're anticipating the biggest turnout you could possibly have when you think about public safety," Walsh said. He noted that prior championship parades have drawn 500,000 to 1 million fans, with smaller numbers coming in winters like that of the team's 2015 Super Bowl win when Boston streets got some 9 feet (2.7 m) of snow.
The parade will kick off at 11 a.m. EST (1600 GMT) at Boston's Prudential Tower and roll down Boylston Street to City Hall. (Reporting by Scott Malone Editing by Tom Brown)
