“Initial rain over the past few days has helped to saturate soils and prime portions of the Bay Area for increased flooding potential as our next [atmospheric river] moves inland,” the weather service said in a statement. “The next round of moderate to heavy rain is expected Monday into Tuesday which will bring additional flooding concerns to the Central Coast where the heaviest rainfall is likely within the Santa Cruz Mountains and the Santa Lucia Range.”

Here’s a look at the forecast storm total precipitation between tonight and Friday. Our biggest concerns are flooding of creeks and streams and an increased risk for downed trees due to the combination of wind and moist soils. Turn around, don’t drown! #CAwx pic.twitter.com/dzZuHNHNW7
