What this means
Forecasts by the Southeast River Forecast Center. Forecasts are issued as needed during times of high water, but are not routinely available. Due to the potential threat of storm surge traveling upstream through the river from the coast, refer to storm surge watches and warnings issued by the National Hurricane Center for this location. Once the threat of storm surge flooding has passed, official river forecasts will resume for this location.
