NowCast Winter

NowCast Winter 2021-2022 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 2021-2022 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, 2022. Click here to learn more about NowCast.
