LOS ANGELES (CBSLA.com) — Several big events could combine Saturday to create a perfect storm of bumper-to-bumper traffic throughout Southern California.

President Barack Obama is slated to make a whirlwind visit to Los Angeles Saturday, with three Democratic fundraiser appearances in just 6 ½ hours, the very same day as USA-Mexico soccer match at the Rose Bowl in Pasadena and Game 2 of the NLDS between the Los Angeles Dodgers and New York Mets at Chavez Ravine.

But that’s not all. Large crowds are also expected at the Jet Propulsion Laboratory’s open house in La Cañada Flintridge, and at the Hollywood Bowl for the Zac Brown Band.

Expected road closures have not yet been released for the president’s Saturday visit, which starts at 1 p.m. at LAX. The president, whose schedule will likely keep him on the Westside, is scheduled to depart Southern California at 7:25 p.m.

The Pasadena (110) Freeway could be the epicenter of traffic for all these events. JPL’s Open House is scheduled from 9 a.m. to 4 p.m. Saturday and Sunday, and parking is limited and heavy traffic is expected. Just a few miles away, soccer fans are expected to stream in all day Saturday for the sold-out CONCACAF Cup between USA and Mexico, which starts at 6 p.m.

Game 2 of the NLDS between the Dodgers and Mets starts at 6 p.m., so heavy traffic is expected on both the 110 and Golden State (5) freeways.
