Los Angeles County officials issued a flash-flood warning Tuesday for areas including parts of the Santa Clarita Valley, following a forecast of heavy rain storms.

National Weather Service officials expect heavy rainfall that could trigger debris and mud flow.

A NWS Flash Flood Watch has been issued for the Los Angeles County burn areas including; Colby, Powerhouse, Station and Williams.

The NWS Flash Flood Watch is also being issued for Acton, Antelope Valley, Lancaster, Los Angeles County Mountains, Palmdale, Pasadena, San Gabriel, San Gabriel Mountains, Mt. Wilson and Pomona effective in the early morning through late night Tuesday.

To help prepare residents, who live in or below the burn areas, for this rain storm and potential debris mud flows, the following are some safety tips:

•         If a flash flood occurs move immediately to higher ground.
•         Be aware of streams, drainage channels, canyons, and other areas known to flood suddenly. Flash floods can occur in these areas with or without warnings such as rain clouds or heavy rain.
•         If a landslide and/or debris flow occurs, danger is imminent, quickly move away from the path of the slide. Getting out of the path of the slide and/or debris mudflow is your best protection. Move to the high ground in a direction away from the path. If rocks and debris are approaching, run to the safest area and take cover.
•         Be aware of any sudden increase or decrease in water level on a stream or creek that might indicate debris mudflow upstream. A trickle of flowing mud may precede a larger flow. Look for tilted trees, telephone poles, fences or walls, and for new holes or bare spots on hillsides. Listen for rumbling sounds that might indicate an approaching landslide or mudflow. Be alert when driving. Roads may become blocked or closed due to collapsed pavement or debris.
