The rain will be nothing like the relatively modest storms that have brought largely beneficial rain to Southern California the last two weeks. Forecasters suggest avoiding travel if possible on Thursday.

What to Know The brunt of the storm will bring widespread rain starting Thursday morning with peak intensity expected later in the day. A flash flood watch went into effect for much of the region Thursday morning and will continue into the night.

Forecasters are concerned the storm could bring mudslides in and near areas scorched by the Palisades and Eaton fires.
