Rain is returning to Southern California, staring on Friday afternoon and lasting into the evening.

The National Weather Service forecasts up to 2 inches of rain in Ventura County northward and a half-inch or less in Los Angeles County.

Thanks to a wet winter, downtown Los Angeles already has exceeded its annual rainfall total with the season far from over.

Stuart Seto, a weather specialist with the National Weather Service, told KPCC late Friday morning that there was a "big change" with the incoming storm system. Originally, it appeared that the weather system that blanketed Northern California was going to make its way down the map to the Los Angeles area. 

Now, Seto said the system Angelenos are going to see "broke off" from the much larger system.

"What that means is that it's stretched itself out and doesn't have as much rain with it," he said. 

For San Bernardino and Riverside counties, light rain is expected late in the afternoon – less than half an inch in the mountains and even less in the Coachella Valley.
