The storm also dropped a record .44 inches of rain in Oceanside, breaking the previous rainfall high of .35 inches for the same date in 1987.
Though mostly light to moderate showers are expected Friday, brief heavy downpours are possible, according to a NWS advisory.
The agency urged motorists to slow down on wet roads.
The weekend is expected to bring a gradual warming trend along with fair weather, NWS meteorologist Tina Stall said.
