Okay, the lights have started to go out at this hour.

Okay, the lights have started to go out at this hour. PG&E has started to cut some power off, and it's also watching to see if it needs to cut more power off. It could end up being 10,000 Bay Area customers, all of this with the aim of reducing fire risk. Let's give you a live look at PG&E's outage map. The areas highlighted in orange are either being told to prepare for public safety shutoffs. The outage could last through Saturday afternoon, including more than 4,700 customers. Now, we understand that in Alameda County, I believe, and Contra Costa County, those have started. Diablo and Sonoma County, about 2,000 people. Saint Helena as well. Those are the ones that are facing potential power cutoffs. Robert Handa is in Danville with where people there have started to prepare for the dark. We are in the northeast section of Danville, which is among the areas that could have their power preemptively shut off by PG&E tonight. People we talked to here say they aren't particularly worried, but they are certainly prepared. Tonight, PG&E is trying to decide if the weather is dangerous enough to preemptively pull the plug on the power for about 11,400 customers in five Bay Area counties: Alameda, Napa, Sonoma, Solano, and Contra Costa County. The East Bay alone has over 6,300 customers in the PSPS warning zone, including the Koski family of Danville, who say the timing couldn't be much worse. Kind of lame, because my wife's about to go into labor, so yeah. Oh, you're kidding me. No, tomorrow's the due date. So what's the plan? Hopefully, we got some neighbors that can help us run the generator when we're at the hospital so we don't lose our food and all that kind of stuff. PG&E says it has been alerting its customers to take those kinds of precautions as PG&E weighs the factors that would trigger the PSPS. When we see some of these factors, including high winds, very low humidity levels, dry material on the ground, um data coming from the field that indicates uh wildfires could occur, and also red flag warnings. When we see enough of those factors coming together, that's when we consider a public safety power shutoff. The San Ramon Valley Fire Protection District has its emergency center ready for the worst-case scenario. The most important part for us is to make sure that if we enter into a red flag staffing event or a red flag warning event, that we upstaff. Uh that's increasing the number of firefighters and the units staffed to make sure that we're able to handle a larger uh volume of either vegetation fires or a larger vegetation fire in the case of one. So from this point on, it is all about watching all the factors that could lead to a PSPS. And again, the factors are not the same for every county. There are 4,700 customers in Alameda County under the same alert, but fire officials there say the fire risks and the possible outages won't start there until tomorrow morning.
