Southern California is bracing for another round of powerful and potentially destructive storms this week.

Forecast

A powerful storm system is expected to move in starting Sunday night, bringing heavy showers and strong wind that could last through Wednesday, said Robbie Munroe, a meteorologist for the National Weather Service in Oxnard.

A flood watch is in effect Monday and Tuesday for many regions of the Southland.

  • MIDWEEK

Storms will give way to sunny skies.

  • WEEKEND

Another “more widespread, stronger storm” is predicted to descend on the region next weekend, Munroe said.

Effects

Munroe said this upcoming storm system will bring “at least that much rain, if not more” as the one that rocked California last week, causing flooding and mudslides, toppling trees and knocking out power to homes. Rivers and creeks, already swollen by earlier storms, overflowed their banks.
