GENERAL NOTES
The debris and mudflow potential forecast is based upon a review of watershed conditions and weather forecasts from the National Weather Service and other weather predicting sources. It represents conditions within the watershed that could lead to debris and mudflow events. Debris and mudflows are highly unpredictable events. The following description is to assist storm response Divisions and emergency response agencies to plan accordingly:
No Phase
- Rain is forecast by the National Weather Service, but the amount of rain and/or watershed conditions are not anticipated to produce appreciable amounts of debris on streets or specific public infrastructure locations. Reports of debris on private property may be received by emergency response entities. Few, if any, structures are anticipated to be endangered, other than those advised to be prepared to evacuate with any forecast of rain.
Phase 1
- Small isolated debris and mudflows possible at specific public infrastructure locations. Streets may be flooded or blocked by debris. Reports of debris on private property may be received by emergency response entities. A few structures may be endangered, in addition to those advised to be prepared to evacuate with any forecast of rain.
Phase 2
- Moderate debris and mudflows possible at more widespread locations. Some streets may be completely blocked by debris. Depending on location and terrain, some structures may be endangered, in addition to those advised to be prepared to evacuate with any forecast of rain.
Phase 3
- The potential exists for significant debris and mudflows to be widespread over specific areas. Streets may be blocked and considered unsafe for travel. Many structures could be endangered by debris and mudflows. Extreme caution should be exercised below uncontrolled canyons due to sudden debris flows.
