Regardless of the outcome of the UCLA-USC football showdown on Saturday, forecasters said it may rain on the victory party of either the Bruins or the Trojans.
Mike Smith of WeatherData Inc., which provides forecasts for The Times, said a low-pressure system in the Pacific--about 1,000 miles west of San Francisco on Thursday--was headed for Southern California. With nothing to block its path, the front edge of the system should reach the Los Angeles Basin by tonight, bringing with it a chance, initially, of thunderstorms.
The showers may hang around until early Saturday evening, several hours after the Rose Bowl decider is over at the Los Angeles Memorial Coliseum.
Smith said the storm may not be a major one--"maybe as much as a third of an inch of rain"--but football fans and others who are outdoors on Saturday should pack some rain gear. Heavier rainfall is expected in the local mountains, he said.
