vaccination for indoor customers. nbc bay area news. a major milestone reached in alameda county. they posted this tweet saying 1 million people living there are fully vaccinated against covid. the county is thanking people for getting their shots, continuing to wear masks, and staying home if they're feeling sick. to the fire coverage. we're continuing to keep a close eye on a big fire burning about 45 minutes south of lake tahoe. it exploded to more than 65,000 acres. it started on the fourth of july. firefighters say it was sparked by lightning. lighter winds have given firefighters and opportunity to cut new containment lines while hand crews are directly fighting the fire on several fronts. more than 2,000 people have been evacuated. and the dixie fire has burned nearly 200,000 acres and threatening thousands of buildings and homes. the fire burning gained more ground overnight. up nearly 14,000 acres.

all though it has torched largely remote, unpopulated areas, it's threatening businesses and homes an along the northwest coast. it's 19% contained. let's go outside. a live look at walnut creek. you can see the hills are dry, the air is warm, fire danger is high. heading this way another chance of lightning. that's not good for fire discharge. what is the chance we'll see more lightning? >> we'll be watching the next 24 hours very closely. in the meantime, off to the east seeing thunderstorms around the see year area. what looks like thunderstorm near the moment at the did dixie fire radar picking up, unfortunately, ash being thrown aloft of the strong winds. a sign of intense fire activity. and unhealthy to hazardous smoke levels toward lake tahoe. so clearly a big fire impact there around the dixie fire.

closer to home, things relatively quiet. not seeing smoke problems here and don't have the thunderstorms. but that could change in the next 24 hours as monsoon moisture, much like we saw last weekend, sweeps back over the bay area. so thunderstorms will increase in coverage over the sierra during the day tomorrow. as we head to monday and tuesday, you'll notice things are going to turn muggy around the bay area and we'll see, unfortunately, another chance of lightning spark fire danger. we'll talk about that and be getting close to 100 degree temperatures ahead in the seven-day forecast. coming up in about 10 minutes. >> thank you so much. coming up on the special i addition of nbc bay area news. tokyo. it's calm on the bay now but a tropical storm is on the way. some changes to competitions. the games haven't won but yes two mascots. we'll introduce you to the robotic version of them and show you some of their skills. but, first, we want to issue a

they react. so when you wave at one of the robots, she waves back! she blows you kisses. >> nice. speaking of which, let's get back to tokyo right now. it's a live picture. northern tokyo bay. looking good. trouble may be on the way. an approaching tropical storm is forcing changes to the athlete's schedules. organizers moved up rowing be i a day. everything has been moved up to sunday instead of monday. organizers said they're looking at tuesday's schedules. this is the first time for events in the games to be rescheduled because of weather. which is kind of surprising. the games have been going on for so long. but here we are. >> yeah. and this time of year the west pacific typical of what we see this time of year. similar to the atlantic. around tokyo it feels like miami or new orleans this time of year. you can see the maritime tropical air has helped to power up the tropical storm crossing through the coastline through the next few days.

and you'll notice we could be looking at rain totals of about 2 to 3 inches. the highest impact will be on monday. we might see a little more of the carry over into tuesday. so be watching this closely. winds expected about 30 to 40 miles per hour. some heavy rain at times. might see some lingering impacts into tuesday for those events. rowing, obviously, impacted by that. could be impacting things in tokyo over the next couple of days. closer to home, our watches for tropical weather that bring intense rain and unfortunately might bring lightning. hazy skies and 79. hot temperatures continue inland. 94 degrees. humidity at 10%. walnut creek 95%. san francisco the fog and the mist and only 62 degrees. some of that stratus quo, as we like to say in the forecast, continuing into tomorrow morning. so, again, 50s to start. drizzle at times on the coastline. temperatures tomorrow not changing a lot. near 80 in san jose.

should see upper 80s to low 90s around the trivalley. and 80s up toward the north bay. the attention will be on the moisture. that's a look at the fog tomorrow morning. notice on the right side of the screen, that's mid level clouds increasing instability that will first start off over the sierra during the day tomorrow. as we head toward this time tomorrow toward sunday night, you can see we've got the clouds that will spill to the west. this monsoon energy will bring in the instability and a lot of lightning potential. that's where fire danger will be elevated as we wrap up the weekend. there's more of that. it continues moving around high pressure. you can see the bands of showers past near the bay area as we head to monday and tuesday. and the temperatures also will be trending hotter. so the two things we're watching fire danger is the chance of more lightning. especially for the coastal range mountains and toward lake county and mendocino county. and moving forward in the ten-day forecast, look where the

high temperatures are headed. livermore close to 100 had degrees. you can see the temperatures staying hot. we see the chance of maybe some lightning at times into monday and tuesday. temperatures there, too, quite hot. even san jose getting a taste of 90. mainly in inland valleys north bay and east bay the follow up to the muggy conditions that we'll see that will help san francisco climb into the 70s. increase fire danger but the follow up where we have to watch for is the hot temperatures. once the monsoon moisture shuts down, we could see highs close to 100 degrees come wednesday. so things are nice and calm right now. we'll be watching the radar closely as we wrap up the weekend to see if the moisture, which is over the sierra tomorrow moves closer by monday. >> good. the moisture sounds so good. we can use it everywhere because the hills are just dry but you point out you might get lightning here and rain over there. it's not necessarily connected. >> yeah. they may not be associated with each other. or not like arizona deeper

moisture with the flash flooding. the rain coming isn't enough to offset the record-breaking dry fuel we have on the hills and not sustained enough to offset the risk of lightning in some of the storms. >> okay. thank you. up next working to go green. the historic way the olympic flame is being fuelled at this year's games. okay. another look at tokyo bay. we can't get enough! >> it's gorgeous. >> yeah. the olympic rings and the bay. >> yeah. >> we're back in a moment.
