Winter isn’t done with us just yet. A powerful storm system is expected to produce severe weather for millions of Americans from coast to coast this week, bringing heavy rain and strong winds to California,

The forecast comes days after an expansive storm similarly trekked across the U.S. last week, unloading snow in the northern Plains and bringing tornadoes and wildfires to the South. At least five storm-related deaths in Nebraska and Mississippi were tied to that storm.

The Southern California area has one more day of sunny conditions before a set of storms will bring moderate to heavy rain and snow over the next couple of days, forecasters say. The National Weather Service said a slight chance of rain will develop overnight Monday as the first storm continues to make its way into the region.
