Weather officials have placed a flash flood watch on northeastern Los Angeles, the San Fernando and San Gabriel Valleys, and sections of Santa Barbara and San Luis Obispo counties. Rain showers and thunderstorms are also likely for the area.

The National Weather Service warns of heavy downpours, strong thunderstorms with hail and wind gusts, and possible flash flooding through Monday. The highest threat of flash flooding and strong thunderstorms will occur through Sunday night. There's an especially high risk of flash flooding and debris flow in recent burn areas, like the region burned by the La Tuna Canyon fire last week. The L.A. Times specifies risk for the Antelope, San Gabriel, San Fernando and Santa Clarita valleys. Other burn areas like those of this summer's Whittier and Alamo fires are at high risk for debris flow.

The NWS describes a low pressure system expected to drift off the coast and travel inland, bringing with it thunderstorms and rain showers through Monday night. It will also cause temperatures to cool down the rest of the week.

Officials urge drivers not to drive through flooded roadways and for campers and hikers to pay particular attention to the sky, as weather patterns can change quickly.
