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
- 26 - Expect flooding along several thousands of acres of the entire length of Attoyac Bayou to continue for several days.
- 22 - Expect moderate to severe lowland flooding of timber in and near the river floodplain. The bayou will continue to remain above flood stage for several days.
- 21 - The bayou will continue to slowly fall during the next several days, and lowland flooding will gradually decrease.
