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
- 11 - Flooding will affect areas along the river from Wilmington to Lawrence. Some roads will become impassable including Route 114 near the I-495 interchange. Follow the advice of local officials, and evacuate if asked to do so. Do not drive into areas where water covers the Road. Basement flooding in low lying areas is likely and valuables should be moved to higher ground.
