and should not be coming near vulnerable patients unless they are. >> reporter: the order coming down from the state department of health and not a private employer eliminates one key challenge according to the professor. >> employer may have to negotiate with a union, the state does not have to. they are not the direct employer. >> reporter: the nurses association issued this statement. we strongly believe all eligible people should be vaccinated while respecting the need for medical and religious accommodations. the order does allow exceptions. >> the state allows people who are exempt to continue working as long as they get tested and wear masks. so, accommodation is you don't have to vaccinate but you have to test and wear a mask. yes, it is perfectly legal. >> reporter: the chair of the ucsf department of medicine says it is time. >> i am all in favor of it from the very beginning it has been appropriate for health care

worker who's take an oath to do no harm, at least the doctors do, to keep themselves safe for their patients. >> reporter: andrea, does it effect only health care workers? what about other people coming in and out of the medical facilities? >> reporter: well, ken, this was a two-part order from california department of public health. the second part of the order effects all visitors to hospitals, skilled nursing facilities and other medical facilities. they will have to show proof of vaccination or if not a covid- 19 test that is negative from no later than 72 hours. >> all right, good to know. reporting live, thank you for that. looking live at san jose tonight. a vaccine mandate for city ffin juser two weeks. beginning august 23rd employees must be vaccinated or they need covi tests. anyone who does not adhere to those rules could be placed on unpaid

greenville area they described intense fire conditions. including swirling winds and unstoppable crown fires where the fire jumps from tree to tree. flames shooting hundreds of feet into the air. >> when they lost greenville it wae crown fire. one of the, you know, fastest moving dangerous fires we can face and very hard to stop. >> we have had some pretty extreme conditions out there over the last 48 hours. we have a lot of folks in there. >> reporter: katie, where is the strike team now and what are they going to be doing tonight? >> reporter: so right now they are close to the chester area and that is going to be a critical area tonight on the dixie fire because the winds have shifted and the fire is now blowing back directly towards that community. so, they are going to in the chester area tonight doing structure protection all night tonight. they worked 24-hour shifts, they will be off midday tomorrow and back at it again on the weekend. >> long hours. all right, katie, thank you.

colf area have been asked to conserve water. stop all nonessential use to make sure there is enough water for the firefighters. some of that smoke may begin effecting our own air quality here starting tomorrow. r chf meteorologist has a reporr: the wind shifted, katie referenced concerning to firecrews because it is pointing the fires in a different direction and the smoke plumes in a different direction. this is the smoke plume, the winds turn to the north which is going to take the smoke from the monument fire and mcfarland fire to the north and send some of it down into the pay area. this is a forecast model simulating the smoke concentration right at ground level. we are focused on ground level smoke that will effect our air quality. this forecast model anticipated a higher concentration of the smoke to move into the north bay early tomorrow morning and spread across much of the bay area as we head through the day on friday. not all bad news, though, the latest update of the forecast model

shows the air quality improving as we head into the weekend. the smoke does not disappear. a little more elevated in the atmosphere and while it does not look great there, there is a hazy look overall. we don't have to worry about breathing it in. now we are looking at the possibility of the air quality going into the unhealthy for sensitive groups category tomorrow. for the north bay and the east bay, everybody else at the moderate category, air quality forecast it is tricky. it depends how much of the surface smoke gets blown in and how much of the smoke in the atmosphere gets pulled down to ground level just by gravity and the long it is in place the better chance it comes towards us. it improves next week. the management district a different scenario in mind tomorrow. we will look at that coming up. still ahead tonight. >> each of you are responsible to some degree. >> a coworkers of the vta rail

yard shooter gives an earful to the agencies leaders y. he says there are huge failures months and years leading up to the attack. cases of a new coronavirus variant have been found in santa clara county. tonight, doctors explain how concerned we should be about delta plus. >> we believe that it is the least as bad as delta. and the extreme drought forcing unprecedented action. why california's power supply will take a hit.

least as bad as delta. >> reporter: the doctor is a expert at ucsf. he is as there is still a lot to learn about this mutation. >> number one, it is more transmissible, number two, does it evade vaccines? and number three, does it make you sicker? >> having additional variants is going to be expected with any virus. >> reporter: infectious disease expert at stanford school of medicine as health experts continue to track and learn more about mutations such as delta plus, she urges people to do what they can to make it harder for the virus to spread. >> what we can do is get vaccinated and keep ourselves from getting infected. that is how you stop the viruses from mutating. >> reporter: the health experts say they expect more variants to emerge over time. the best way to combat this is to get more people vaccinated. the more people that are vaccinated the fewer people the virus can

policies of fernandez, who you employed and failed to oversee. that is behind us. i am here to tell you each of you it is past the time to investigate. that the employees in the department are asked what was wrong? what created the stresses and the hostility that pushed cassidy to kill my friends. >> nine vta employees were shot and killed when their coworker opened fire in may. we reached out to vta for a response but have not heard back tonight. unprecedented move today has results of the drought emergency water levels at lake oroville, they are so low right now one of the three power plants had to be shutdown. that is because there is not enough water to spin the turbines and generate electricity. energy experts say the loss of power can be replaced by increasing the use of natural gas and

importing electricity from other states. we go from that to our weather. we will not get more water. we will get wind and heat. >> and smoke to go along with it. let's start with the air quaility and how -- air quality and how it will change. we took a look at the ground level smoke. this simulates the smoke through the whole depth of the atmosphere. not just the ground level that we breathe just what you will see. the haze in the air. we anticipate plenty of haze throughout the day on friday and that lingering in place in the first half of the weekend as well. for the onshore winds kicking back in on sunday it helps to improve the air quality and should be back to good air quality across the board by the time monday rolls around. how much of the smoke moves in at ground level or moves in farther off of the ground and then settles down due to gravity? i am anticipating we are in the unhealthy for sensitive groups in the north bay and the east bay. the bay area quality management district

is more optimistic. moderate air quality, across the board on friday if you have someone in your family, you know someone with severe asthma, a breathing difficulty you want to make sure they are prepared for decrease of air quality. regardless which category we now, no smoke no fog. temperatures are around 60 degrees. the numbers will not change a lot heading through the rest of tonight. the fog will not be as thick or as persistent as it was early today. so, it will be out there and spilling into the inland valleys early on friday. backs up quickly. plenty of the hazy smokey sunshine throughout the day. the temperatures will heat up from a tart that is close to normal -- start that is close to normal. 3-5 degrees cooler than right now. the temperatures will heat up. along the coast, making it into the lower 60s. temperatures farther in the
