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
- 70 - The river exceeds the levees - flooding is widespread, disastrous, and life threatening -
- 65 - The river is approaching the top of the levees - residents should be prepared to evacaute rapidly to several tens of miles from the lower Rio Grande channel as emergency officials direct - persons in the flood plain should monitor the latest stage and forecast levels of the river continuously.
- 58 - Major flooding covers the flood plain inside the levees-threatens lowest residences in Brownsville and Matamoros - persons vulnerable to lowland flooding should move equipment to higher ground and monitor the level of the river especially if heavy rain conditions develop.
