summarize basin hydrological and meteorological conditions. It also assesses the
potential for flood risk. The outlooks are based on current and forecast
conditions.

outlook monthly throughout the year for a continuous water watch. This
can be found at https://www.weather.gov/ohrfc/wro

Factors considered in assessing flood potential include antecedent
conditions, past precipitation, current streamflows and reservoir levels,
soil moisture, water content in snow cover, ice conditions and future
precipitation.
