A new powerful storm will hit Southern California this week, the latest in an epic year of rain and snow.
Here is a breakdown of what to expect and when the rain will end.
Timeline
Tuesday: Storm conditions will intensify in the Los Angeles area and across much of the Southland.
“It really hits us hard tomorrow — that’s when we’re going to get the heaviest rain, the strongest winds and the heaviest snow in the mountains,” National Weather Service meteorologist David Sweet said Monday.
Wednesday: Rains will taper, with mostly cloudy skies by evening.
Thursday-Sunday: Conditions will clear, with clouds giving way to sun in many areas.
Next week: An unsettled pattern may begin again around Monday, Sweet said. “We have our eyes on another storm for early next week,” he said.
