National Water Model Hydrograph
Official NWS streamflow forecasts are produced by NWS hydrologic forecasters for river gauge locations using hydrologic models which are calibrated to that location. This process considers additional guidance and information, including local expertise and experience, to produce the best forecast possible. The NWM output provides supplemental guidance to NWS forecasters and should not be considered an official NWS river forecast.
Flood Impacts
- 77 - Major Flooding. Willowside Road inundated and adjacent vineyards under many feet of water.
- 74 - Moderate Flooding. Water levels reaching underside of bridge deck at Willowside Road. Further rise in water levels will cause backwater effects at the bridge with waters seeking alternative routes around bridge with possible build up and overflow of roadway. NWS will issue a Flash Flood Warning, if not yet already issued.
- 70 - Minor Flooding. Ewok Trail begins to flood. NWS will issue an Urban/Small Stream Advisory, if not yet already issued.
