A strong storm system, which has been tapping into significant tropical moisture, has been pummeling Northern California with rainfall all day Sunday — enough to cause major flooding and landslides.
As this system continues to move across the west, the rain will arrive in Southern California by Monday morning. We'll begin with lighter rain in the morning hours, but expect everything to pick up to more moderate and heavy rain Monday afternoon and evening.
Widespread rain will track from west to east across the region. During this time, we will also have strong winds, especially across the mountains and deserts.
Snow levels will stay high; therefore, the focus remains mainly on rain across the mouintains. We may get a dusting of snow late Monday in the highest elevations as this system tracks off to the east, but this will largely be a rain event.
In terms of temperatures, it will be cold with mostly 60s across the Southland.
Overall, be prepared for slick roadways, and make sure to give yourself more time for the morning and evening commutes. Also, don't forget warm jackets, umbrellas and other rain gear.
By Tuesday, conditions will be dry, sunny and warmer.
