Multiple rounds of rain will return to the Bay Area Saturday through Tuesday, bringing with them the possibility of flooding, landslides, power outages and other problems, according to weather officials.
Here's what you need to know about the upcoming storm systems.
When will it be raining in the Bay Area?
Following a break Friday, the rain will return Saturday and continue over the next several days with some quick breaks in between.
Saturday and Sunday will feature periods of heavier on-and-off rain, especially in the North Bay and the Santa Cruz Mountains.
"The brunt of the storm will be hitting us Saturday evening into Sunday morning where we see more waves of widespread heavy rain," NBC Bay Area Meteorologist Kari Hall said.
Storm systems Monday and Tuesday are expected to be stronger than the weekend ones.
"Not a lot of breaks here," Hall said. "It's going to be very busy."
