Southern California cleaned up on Saturday after its biggest storm in years unleashed a wave of rain and snow that killed at least three people and triggered flooding, mudslides, high winds and power outages, officials said.

Vital highways and railways were shut down and sinkholes opened on main roads under the heaviest rainfall in the drought-stricken region in at least five years, according to the National Weather Service.

In one of wettest spots, near Santa Barbara, over 10 inches (25 cm) of rain fell on Friday with several other stations in Southern California reporting at least 9 inches (23 cm), said meteorologist Patrick Burke of the Weather Prediction Center.
