Southern California is bracing for a severe winter storm over the Christmas holiday, with forecasters warning of heavy rainfall, gusty winds and potential flooding.
The storm will bring prolonged periods of heavy rain Tuesday through Saturday, with totals expected to reach 4 to 8 inches in coastal and valley areas and 8 to 12 inches or more in the foothills and mountains by Saturday night, according to the National Weather Service. Officials are urging residents to take necessary precautions as flooding and mudslides could pose a serious risk throughout the week.
The first and most significant rainfall is expected Tuesday night into Wednesday, when moderate to strong atmospheric rivers will hit the area. During this period, total rainfall could reach 2 to 5 inches in coastal and valley areas, 5 to 10 inches in hills and mountains, and hourly rainfall rates of 0.75 to 1.25 inches possible. The continued rainfall and intensity have raised concerns about widespread urban flooding, mudslides and hazardous driving conditions, especially during one of the busiest travel times of the year.
Flood warnings are in effect in all four counties from Tuesday afternoon into Wednesday night, with the National Weather Service advising residents to begin taking protective actions immediately.
In addition to the heavy rain, strong southerly winds are expected Tuesday and Wednesday, especially in the mountains and foothills, potentially blowing down trees and causing power outages. Officials advise residents to avoid swollen creeks and rivers, avoid unnecessary ocean activity and take precautions such as parking vehicles away from tall trees during strong winds.
Forecasters emphasized that the timing and intensity of the storm could still change and encouraged residents to follow the latest updates from the National Weather Service and KTLA meteorologists.
