Clouds moving in, tracking instability with height here on those clouds in San Francisco. Thats a good enough indication that the area of low pressure, this storm system were tracking, is getting closer. Its already produced 14 Lightning Strikes the past three hours north of bate area. We think as we head throughout the next 24 hours, as that storm system gets closer and pushes across the bay area there will be slight risk of isolated thunderstorms. If we do get any that do develop we could get a bit of hail. My main concern with that storm as it moves over is the potential here of dry lightning that again could spark wildfires. Well have details on when that storm moves out and if it could mean any kind of rainfall across the bay coming up. Weve been talking about fire season as it gets off to an early start. San francisco showed off a critical tool to ensure theyre ready to battle fire in the city. An underground water tank.

Its been an eyesore here for about six months but soon you wont even know its there, it will be paved over. Another one locate not far from here. We got a chance to see what it looked like underground. Fire chief Joann Hayes White gave us an underground tour of the cistern tank located at 37th and irving in San Franciscos sunset district. It provides standing pots of water if we need it in the event of a largescale emergency. We can tap into that water source and suppress a fire. Reporter the tanks hold 75,000 gallons of water. Theyre strategically located in over 100 areas throughout the city. The city learned a hard lesson in 1906. Just relying on the existing water supply system wasnt necessarily enough to protect the city from a huge fire. Reporter San Francisco knows about huge fires. The last time water was used from a cistern tank was in 1989 during the loma prieta earthquake fire. The tanks were not used during the march mission bay fire. But the city is thankful the money was there to pay for the 30 tanks that are now under construction. Taxpayers passed a bond measure four years ago that generated 1. 4 million to pay for 30 cistern tanks. A new measure is on the ballot for this june. Proposition a. To generate 55 million to build more. Were good planners in the Fire Department and we know that our history has showed us there are water mains that can break. So we want to be able to have other options to deploy in the event of system failures. Reporter once all the cisterns being built under this phase are complete, there will be 180 of them throughout the city of San Francisco.

Coming up, a multimillion dollar cleanup at one of the bay areas largest and most toxic sites. Governor brown not mincing words when it comes to Climate Change. Why he says california needs to be on the forefront of the battle over Global Warming. Im scott budman on a school bus. This is no ordinary bus, its 100 electric. And will soon be powered by the sun. Well take you on an exclusive first ride coming up. At 6 00, she was left out of her senior yearbook because only boys were allowed to wear a tux and tie. Now the school is doing more than apologizing. The drastic step it took to make things right and why the family has declined. People who worked at one of the bay areas largest and most toxic sites says the cleanup is being botched. And the Publics Health and safety is at risk because of it. Investigative reporter vicky nguyen is here with what she learned from insiders at Hunters Point. Reporter Hunters Point is a former naval ship yard undergoing a massive transformation. 800 acres of beautiful waterfront land along San Franciscos southeastern edge. This is all to be turned into offices, homes and shops. Insiders who spent years on the site working to clear it of radioactive contamination say the cleanup cannot be trusted. They say they documented major violations and federal regulators have failed to protect the public. Its playing russian roulette with the health and wellbeing of the general public, the workers that handle it, and also the quality of the environment. I wasnt worried about my paycheck. I was worried about the wrong thats being done to the city of San Francisco and its communities around wherever theyre shipping this stuff out to. The federal investigators declined our request for an interview, but said in reports they were unable to substantiate the insiders claims. Tonight why those on the front lines say they are now taking action to expose what they witnessed. We investigate tonight at 11 00. If you have a story for us, call our tup line 888996tips. Or send us an email to theunit nbcbayarea. Com. Governor brown continues to sound the alarm about Climate Change calling on california to lead the charge. The governor addressed the issue today at a conference on agriculture. This was in sacramento. He says Global Warming has already caused the state to experience a longer and more destructive fire season. Its also drying up prime california farmland. He adds, we need to be in the front of the fight against Global Warming. We have to get other states and other nations on a similar path forward. And that is enormously difficult. The governor was met with protesters as you can see who oppose his support for fracking. Thats the practice that Oil Companies use to crack rock formations to release oil and glass. Only on nbc bay area, the future is here. Gilroy, to be exact. The Big Yellow School Bus is now green. Our business and tech reporter scott budman is in the south bay where he got an exclusive first drive today. Any differences from the Traditional School bus . Reporter yeah, quite a bit. And as you know, Traditional School buses havent changed in years. But all that fuel can add up and be very expensive. So maybe some Green Technology along with maybe some solar pan theys can help cut costs. With that in mind several Silicon Valley businesses along with a San Jose Group called breathe california are partnering to build electric buses. Basically changing out whats been under the hood for batteries so the buses plug in to charge up. Eventually, they say, the plan is to charge those batteries with solar power. It takes on average 17,000 a year to run a regular school bus. So if we can get all that free from solar energy, then schools can use this money for real school stuff. Reporter the first students to ride the electric buses to school will be in gilroy. That will start next year. Gilroy says it will officially announce the plan later this month. All this does not come cheap. Each bus costs about 150,000 to upgrade. But if those facts are correct, if they last nine or ten years, theyll pay themselves off in fuel alone. Our school buses are changing. They are. And our weather is changing a bit. Weve possibly got lightning in our future. Yeah, thats right. On this monday, a little bit of an unusual forecast for late may with this lateseason storm thats shaping up. Were tracking the core of that low pressure system just offshore. Not only 14 Lightning Strikes the past three hours, but this could bring lateseason snow in higher elevations. More on that coming up. We want to underscore the risk of Severe Weather the next 24 hours. Nothing in terms of intense, heavy, widespread rainfall. But we may get isolated Lightning Strikes as the core of low pressure moves closer. The highest risk here would be dry lightning that could spark wildfires. Lets take you outside of the Sky Camera Network right now. The other thing youve noticed while it cooled down this weekend, a cooler breeze right now on this monday. Right now 60s across the bay. North bay averaging 66. For the east bay, 64. Right now in the south bay, 65. Well take you to the peninsula. Weve got 66. Winds primarily out of the west. Notice just a little bit of lift in those clouds right now. Cumulus cloud action happening across most of the bay. Its a sign of some of the instability we are undergoing. So i want to take you to the future cast. It shows us where we may actually get some rainfall. Again, as mentioned, were not looking at any widespread rain moving across the bay. As we progress through tomorrow morning, 6 00 and 7 00, you can see green showing up. What i will say is it doesnt mean necessarily were going to get rain on top of san jose. Theres a decent chance. I think at 6 00 and 7 00 in the morning tomorrow, everyone will have a chance here of light scattered showers. With that we may get a stray Lightning Strike as we head throughout the afternoon. Then check this out, by 6 00 and 7 00 tomorrow, a little bit of lateseason snow, rainsnow mix across yosemite, is possible. As the core of the storm system will mainly take more of a northern and also eastern storm track. Were just getting brushed by the edge of that storm system as it moves closer. The highest chance of getting a Lightning Strike across the hills of the the north bay and east bay through tonight, also tuesday. And the other thing you want to notice, little to no warning with that lightning. Because it may not have rain associated with it. We call it dry lightning. Its just another reason to keep your eyes to the sky and just head inside if you happen to see a lightning bolt. Take a look at our microclimate forecast as we head throughout tomorrow. Temperatures will go up just a little bit. San jose 72. A chance of some thunderstorms. 71 in saratoga. For the peninsula, cool, san mateo 66. San francisco 67 for you near downtown. The marina expecting 63 degrees. For the north b
