Rain expected to linger into Monday as flood watch remains in effect for LA burn scar areas

LOS ANGELES (KABC) -- A flood watch will remain in effect until Monday afternoon. This covers the Eaton, Palisades, Franklin, Bridge and Hughes burn scars. The much-needed rain will help dampen the fire areas, but is increasing the risk of mudslides and dangerous debris flow.

"Thunderstorms producing heavy rain across the warned area, including across the Franklin burn scar and the western portion of the Palisades burn scar. While not immediately likely, a life threatening debris flow will be possible."

A winter storm warning is also in effect until 4 p.m. Monday for the eastern San Gabriel Mountains, where National Weather Service forecasters expect heavy snow of up to 14 inches in some areas, though no more than an inch is anticipated along Grapevine. Gusty winds are also anticipated overnight.

What is the rainfall timeline?

The heavier rain is expected overnight into Monday morning. Light showers will linger through the morning.

Areas along the Grapevine and the Cajon Pass could see about a foot of snow - or more - in higher elevations.

The National Weather Service is giving a 10% to 20% chance for significant debris flows over the Los Angeles County burn scars.

Rainfall totals

Most of the Southland will likely see anywhere between 1/2 an inch to 3/4 of an inch of rainfall from this storm. Areas near the San Gabriel Mountains will see anywhere between 1 to 2 inches of rain.

The valleys and Inland Empire regions may see anywhere between 1/2 of an inch to a quarter of an inch of rain.
