Daniel Swain for Pasadena Star-News — Rose Parade 2024: Ready your umbrellas, there’s a chance of rain

UCLA climate scientist Daniel Swain discusses the likelihood of rain during the Rose Bowl Parade for Pasadena Star News. “The main reason it hasn’t rained that often on the parade is essentially that it occurs on a single day per year, and even at the peak of the rainy season in Southern California the likelihood of rain on any given calendar day is pretty low,” Swain said.
