The first of two storm systems will make its way into Southern California Wednesday night but most of the rain won’t arrive until Thursday.
“The main brunt of the system that comes through tomorrow brings about an 8 to 10-hour window of rain, but there are a couple of hours in there where we get some really strong rain, which poses the threat of some runoff and some flood issues,” KTLA Meteorologist Henry DiCarlo said.
The system is expected to bring 1 to 2 inches of rain to the Los Angeles County coasts and valleys with 2 to 5 inches forecast for the mountain and foothill areas Wednesday through Thursday, according to the National Weather Service .
“We’re tapping into that atmospheric river, so that’s going to help aid in a little bit more rainfall … and then a second storm system will move in behind it late Sunday into Monday,” Henry said.
A flood watch is in place for Riverside, San Bernardino and Orange counties from Thursday morning through Friday morning, according to the weather service.
