As the rain slowly dampened roads in the morning, drivers in Ventura County said they were being extra cautious.
"It's slippery, very slippery. I just got done telling my girlfriend to be careful coming home from work," said Albert Caballero of Ventura. "That oil comes up, and it makes it really slippery on the roads."
In Woodland Hills, some residents said traffic seemed considerably more scarce than usual.
"There wasn't as much traffic as I expected, so maybe people have stayed in with the weather conditions. You know, us Southern Californians aren't used to this kind of weather, that's for sure," said Andy Cohn of Woodland Hills.
Sporadic showers were seen throughout the area, and heavier rain was expected at night in the Santa Clarita area and South O.C.
The wet weather had its share of fans who welcome the moisture after a particularly dry winter.
"We need it. I'm always happy about the rain, always," said Susan Williams of Calabasas. "Our flowers and our plants, they need it."
A winter-weather advisory is in effect until 3 a.m. Wednesday.
