LOS ANGELES — A second day of much-needed rain fell across drought-stricken California on Tuesday, but the Pacific storm also brought fresh concerns about possible flooding and mudslides in sodden foothill communities scarred by wildfires.

Forecasters predicted scattered showers Wednesday for Southern California, where the heaviest torrents fell a day earlier. Inland areas east of Los Angeles were expected to see the strongest downpours.

The National Weather Service said up to 6 inches of rain was possible in some areas by the time the storm ends Thursday. But it would take many more similar storms for the state to pull out of three years of drought.
