Here in the bay area that includes Sonoma Napa Solano contra costa alameda and santa clara counties all the purple counties. Were in San Francisco and san mateo or in the slightly less restrictive red tier. Up until now it is not really been clear how the governors new state home order will or will not be in force tonight local Law Enforcement now sharing their plans with us. Our kron fours terisa stasio is live in Castro Valley where the new curfew well begin in about 24 hours. She has details for us now. I think and grant im here in Castro Valley and county Sheriffs Department is in charge of police saying this area its an unincorporated area of Alameda County now i spoke with sheriff about this new order thats going to be going into place whether people are going to get arrested if they are out and about after 10 oclock which is when its going to be going in to fact 10 oclock until 05 00am and he said its really up to us its really on our shoulders about how this all goes down. Hoping to cap the rapid rise of covid19 cases, residents living in purple tier counties. Well soon have to follow a limited stay at home order between the hours of 10 00pm and 05 00am for some this makes sense i do my best just to try to anything that help its important to do whatever we can others not so much one man who didnt want to go on camera lashed out of the governor calling the order ridiculous want to be friendly to our constituents we will advise him and talked to none. Alameda county sheriff greg ahern says his deputies will play a significant role in enforcing the stay at home order. But he says arresting people miss is the spirit of the order not in the spirit complaints, you know a lot of people may not be aware of these things that you know challenge in areas where we a lot of people dont know why find working many hours a day so theyre not made aware following guidelines and the ups and downs of the covid19 a mitigation plan so we have to make sure they have an opportunity to know. That they could be in violation of law. The sheriff says fielding calls about parties or people behaving badly will not be a priority, but he adds. However people are blatantly. Violating this new limited order. We will take enforcement action. The sheriff says that these are unique times and they call for all of us to do our part. Hopefully without the forced to comply. It is a process and never before we see a pandemic in the bay area. Have the in the number of and positive covid19 cases that with and this is definitely a surge. Numbers you know prove the fact the governors following the numbers for the high numbers in the state and also high numbers in allegheny county. And again this is all affecting those 6 out of 9 bay area counties that are currently in the purple tier and again it all goes into effect less than 24 hours. Saturday and 10 00pm reporting live here in Castro Valley, theresa back to you guys thank you theresa. The stay at home order means that tonight is the last night that many businesses will be able to offer late night services, including popular bars like that. Brandon lounge in san jose its been serving cocktails outdoors until 02 00am owner tony griffis tells us while he thinks the curfew is well intentioned. Its ultimately he thinks misguided in. He says it doesnt address the root of the spread. Its not because the bars to close its just move into private residences where theyre having 5000 people are even smaller 20 people were there is no mask regulations and a lot of people dont believe in the mass and youre getting super spreader is there. Not all of the businesses impacted by the curfew are open late but most are operating on a tight margin. The for example invested 15,000 in an outdoor tent furniture another pandemic related supplies and is now expecting their revenue to drop even further when the stay at home order begins. The troubling prediction tonight from San Franciscos Health Director covid cases are surging so rapidly that the county could soon be moved to the purple tier as well as kron fours dan kerman reports the city could soon see additional rollback sunday forced to adopt the new stay at home order as soon as sunday.

From 217 new cases the week of october 12th to 768 new cases this week and if the surge continues, San Francisco could be moved to the purple reopening tear as early as sunday. The choices we. You. I make in the next 2 weeks will determine the trajectory of this holiday season, a purple designation will add San Francisco to the governors 10 00pm to 05 00am curfew. For struggling restaurants that means not accepting reservations after a 30 you have to close sooner so people work less hours people s shifts. That means that people lose money our employees lose money because they wont be able to be at work and well get tips that get base pay. That that will probably cause some places to look at how much more money theyre losing will also mean the closure of indoor museums, Fitness Centers houses of worship. Movie theaters and Outdoor Entertainment centers, Retail Stores will also have to reduce capacity to just 25 . Its unfortunate because like i said in the beginning we were going really really well david island with no we just for fun says he understands from a Health Perspective but says after being closed from march to june. Retailers were hoping to make up some of the losses over the holidays, i was hoping that. The month of december we might be as high as 70 or 75 of normal christmas. But i dont see that happening were back in the purple zone people are or how 100 out home.
