NWS Doppler radar indicates a thunderstorm producing heavy rainfall in the warning areas. Flash flooding is expected and may possibly trigger debris and mud flows. The following are some safety tips to help prepare residents, who live in or below the burn and warning areas, for this storm system and potential debris mud flows:
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.
* 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.
