The National Weather Service was predicting a 50 percent chance of rain for Monday, the Los Angeles Times reported.
The last time it rained on a Rose Parade was Jan. 1, 1955, and it has rained only nine times in the parade's 116-year history, the newspaper noted.
Rain is not predicted for New Year's Day -- which was the traditional day of the Rose Parade. But the parade was moved to Monday under a "never on Sunday" rule adopted in 1983 that moves to the parade to Monday when the holiday falls on Sunday.
