The strongest rain will likely fall in downtown Los Angeles on Friday afternoon as the second of two winter storm systems makes its way across the Southland.
Meteorologists say the two-day forecast calls for the heaviest downpour across Central and Southern California on Friday afternoon before the system reboots again and continues through the weekend.
Between Friday and Saturday night, weather officials expect two to four inches of rain to fall on the coasts and valleys and four to eight inches in the foothills and mountains.
The weather system is dropping more rain on L.A. in one event than it has seen in at least three years.
After the strong rains Friday afternoon, there will be a lull and "the last piece of the puzzle," the low center of the system, is predicted to come onshore for another bout of precipitation on Saturday and into early Sunday morning.
