Flood Warnings

Since the Roanoke River drains a much larger area than any of the other creeks in Roanoke, its flood waters are more easily predicted in advance. To aid in this prediction, the City maintains a number of rainfall and stream gauges as far away as Blacksburg. These gauges allow officials to predict when and how high flooding will be along the Roanoke River. Flooding along the Roanoke River can typically be predicted 6 to 12 hours before it occurs, and warning information will be broadcast over local radio and television stations. In the event of heavy rainfall, tune in to local radio news station WFIR AM 960, or other local radio or television stations like Roanoke Valley Television RVTV-3 to listen for flood warnings in your area. Visit the National Weather Service website for information on flood warnings and current river levels in your area.
