Mudslides possible as big storm is projected to bring heavy rainfall

Snow levels could drop to 4,000 feet, potentially affecting the Grapevine, as storms move through Southern California this week.

Topline: Precipitation forecast: Expect 1 to 2 inches in coastal and valley areas, and 2 to 4 inches in the foothills and mountains. Above 6,000 feet, 1 to 2 feet of snow could fall, while up to a foot could fall as low as 4,000 feet, potentially affecting the Grapevine. Potential hazards: The National Weather Service has yet to issue flash flood warnings, though that could change the closer we get to the storm.

Be on the lookout for evacuation notices in recently burned areas, particularly as the storm peaks. More rain ahead: While this round of precipitation should wrap up by Friday, another storm may arrive early next week..
