I've found this sf bay area newspaper page helpful to quickly get timely data and also think their charts are very informative for principally the statewide perspective. Odd that within the Bay Area cases are dropping/plateau while the statewide is increasing. Conversely So Cal is seeing mainly increases I expect data will be forthcoming that increased social excursions are driving the increase.
