NowCast Winter

Winter 2020-2021 NowCast Predictive Modeling Project

The County of Orange is currently participating in the NowCast project in collaboration with Heal the Bay and Stanford University. The project is operating at multiple beach locations within Southern California during the Winter 2020-2021 season. The NowCast system uses computer models and environmental data to predict daily bacteriological water quality, much like a daily weather forecast. NowCast predictions will be updated daily, during the Winter study period through March 31, 2021. Click here to learn more about NowCast.
