The San Francisco Public Utilities Commission (SFPUC), along with a coalition of other Bay Area water, wastewater, and flood control agencies, is taking action to put new weather radar technology to use, bringing advanced precipitation observations and forecasts to California. This advanced network works like a magnifying glass, giving agencies and the communities they serve a clearer, real-time view of atmospheric rivers and rainfall intensity. It helps show where the heaviest rain will fall. This improved data enables public agencies and communities to prepare and respond when dangerous storms approach the coast. And, in our drought-prone state, it provides water agencies pinpointed data to maximize water supply reservoir storage.
