Southern California saw some rainfall in the first of two storm systems expected to pass by through the weekend, but it was scattered and mostly light.
The National Weather Service said radar showed showers running across the region early Friday but that not much of the rain was reaching the ground, according to the Associated Press.
Lyons Peak in San Diego County accumulated more than a half-inch of rain by 5 a.m., but many other locations had received only a few hundredths of an inch.
John Dumas, a meteorologist with the weather service in Oxnard, told KPCC that overall only about a tenth of an inch to a quarter-inch of rain was expected.
There is a slight chance of thunderstorms, but mostly in the foothills and mountains.
The chance of thunderstorms could increase Saturday as the second low-pressure system comes onshore from the Pacific Ocean, bringing with it up to another half-inch of rain, Dumas said.
Thunderstorms are more likely on Sunday, which could also see more showers in the destabilized air behind the second storm, Dumas said.
"Three-day total on all of this is probably coming in at an inch or less in the coastal and valley areas. As you start heading up foothills and mountains, it'll increase up to maybe an inch and half," Dumas said.
The weather is expected to clear heading into next week, but by the end of the week another system could bring more rain, Dumas said.
Despite a strong El Niño this year, rainfall totals are well below normal across much of Southern California.
