A low pressure system near the Bay Area is expected to shift southward Sunday evening, according to National Weather Service. As it moves farther south, it will draw monsoonal moisture from Mexico and Arizona, increasing the chance for thunderstorms across the region.

The potential for flash flooding is greatest in the foothills and mountains, including the Antelope, San Gabriel, San Fernando and Santa Clarita valleys. Heavy rainfall could cause debris flows in areas blackened by recent wildfires, including the Alamo, Whittier, La Tuna, Sand and Fish burn areas.

Weather service meteorologist Curt Kaplan said showers are expected to taper off Monday as the system moves out of the area.
