Stay at Home
The governor of California has issued a stay at home order for the whole state. This follows Los Angeles County and some other areas issuing the same earlier today. Statewide will be easier so people aren't just going to the next county over.
I didn't hear the details, but for L.A. County it was groceries, pharmacies, hardware stores should remain open, plumbers and electricians and similar trades should be vigilant but can do their jobs, medical and governmental services as well. Indoor malls closed. Most stores at outdoor malls closed, if not on that essentials list.
I haven't heard much about industry, nor delivery services. If they close Amazon and other online retailers you'll have a lot more people out shopping. I also didn't hear anything about restaurants doing deliveries. ETA--the governor just said that the restaurants will be available.
