Run off from the napa river causing plenty of concern in the north bay. Lets look at the situation. As you can see, rushing river there. Jody hernandez continues our coverage from napa county. Jody, people in the area hear about storms like this, they get ready for flooded roads. Reporter they sure do. And roads are flooded. The rain really hasnt let up all day here in napa county and it has left the road were standing on looking like this. That is water were told from the napa river and it spilled right on to the road. Ill tell you, this is just one of several trouble spots in the north bay. Nonstop rain has folks in napa county navigating through waterlogged roads. Some of the streets have taken on so much water theyve been closed down. We just want people to stay away from the trails and cross roads. Its, you know, not a good place to go right now. Reporter one of the worst hit areas just north of saint ha lena, this lane looks like lodi lake, runoff from the napa river has poured into the roadway and into a nearby vineyard. We just moved here last february, so were new to all of this. Reporter nancy barness house is at risk. She has sandbags, but the water is on the rise and its unsettling. One neighbor appears to be trapped in her home. Her driveway has become a fastmoving waterway and shes riding it out inside. Its a lot of water. Im glad i know how to swim. Reporter and were back here live. Youre looking at lodi lane. We are told that this morning it did not look like this at all. You could actually drive through it, but the water started rising and it rose fast. If we can pan over, you can see the nearby vineyard is also water logged. Neighbors are joking that they hope this means were going to have some high quality grapes. Folks are holding their breath here in this neighborhood, hoping that the rain does not make it into their homes and so far so good. Reporting live in napa county im jodi hernandez, nbc bay area news. Thank you, jodi. As one would expect, the storm is triggering power outages, more than 42,000 customers without power in the bay area, most on the peninsula. Youre looking at the pg e map right there. There are thousands of people out of power in the north bay and the south bay. And the storm is pounding the Santa Cruz Mountains today. High winds, torrential rain fall. Rip boone has been there all day long. Reporter terry, its rising as we speak, about 10 minutes ago there was a Fire Department that came down here and said this is your live shot. Let me know something, the next 30 minutes the water at this point should be way above this bank and all the way into our parking lot where our satellite truck is located, so were out of here pretty soon. You see this river, the residents are very serious about this, so much they told me to tie this rope around my waist just in case something happens at this particular standpoint where im at in this location. Its a serious nature because they know this water can do some major, major damage to their home. This one is scarier because the rain keeps coming. Reporter life for those who live along this river continues to be a concern. Its been in my backyard and up to my fence line and this house has flooded before. Reporter this is not new as most residents have lived here all their life. Are you getting the heck out of here . Oh, yeah. I came to check on my friend because i live in fellton and i know shes all by herself. Reporter deeper in the Santa Cruz Mountain, a line of storms pound route 9 from felton to north of boulder creek. This power line shutting down the road and shutting off light to customers. If you didnt have a generator, likely you were in the dark. A severe rain day for Santa Cruz Mountain residents thats far from over. Back here live and the water is continuing to rise and add to the worries for residents here. Were hearing reports there is a Mountain Lion roaming around these areas, so much more of a bigger worry for them every time they walk out that door, but right now the biggest concern, they may have to leave their homes tonight because this may be in that direction. Were live in felton grove, rick boone. Thank you, rick. The rain shut down a road we want to show you near the rv park. The water is up to the wheels of the cars on the streets and some folks tried to move their cars off that road unsuccessfully. Yet another reminder to avoid driving through standing water. Thats a bad move. Thats a bad move. Seek shelter was put in place for people who live in that area. That usually does not end well. Also take a look at what it looked like in oakland as rescuering jumped into action after these people drove their car into the water. Michelle, youre joining us from golden gate where a downed tree there blocking the road. Reporter thats right. Im here at 19th and lincoln after avenue thats been closed for several hours. The last half hour, emergency crews have opened the left side allowing one lane of traffic to go by on the northbound side causing some major traffic delays. A big tree hit a light pole and its been blocking the street. This is one of many locations that emergency crews have been handling downed trees. I heard a big boom and looked out the back window and the trees in the back. Cant see out my back window at all. Reporter this woman and her family say theyre grateful the roof didnt collapse when this giant oak tree splashed on to their apartment complex in San Francisco sunnydale neighborhood early this morning. My heart is still beating, so i just want to go back home. I cant wait to go back home. Reporter the red cross offered help to seven tenants in the building who were evacuated after the tree came down. That was scary. It was like right next to my window. Reporter across the bay in oakland, emergency crews responded to doolittle drive. A cab driver lost control and spun off into the estuary. The car was only three to four feet underneath. Reporter koi justice said the driver was in bad shape when he was transported to the hospital. The cause of the crash is underinvestigation, but chief justice is urging everyone to slow down in rainy conditions. Stay off your phones, Pay Attention the road, Pay Attention to the other driver. Reporter in San Francisco, police directed traffic away from 19th avenue near Golden Gate Park this afternoon after a tree smashed into a light pole. Back out here live, weve been driving around all afternoon and the good news is the roads dont appear to be very slick. We have had a lot of rain this week, but a lot of people are going extremely fast, so take it slow and those wind gusts especially on the bridges is something youll want to watch out for. Reporting live in San Francisco, im michelle roberts, nbc news. Thanks a lot, michelle. Good advice. The storm is creating havoc for Airline Passengers as well. So far the airport has cancelled 71 arrivals, 62 departures, another 289 flights have been delayed either coming or going and live right now at oakland airport, theyre reporting seven departures, seven arrivals have been cancelled another 40 flights are delayed. In this live picture here, looks like theyve got some isolated flooding out near the airport and winds blowing as well. San jose airport, reporting no problems so far today. It sounded like lightning, the sound of a huge tree limb cracking woke up an entire neighborhood. A 50yearold cedar tree fell for at least six hours neighbors say the limb was held up dangerously by the power lines. One man who lived in the neighborhood for years says that this tree has been strong through storm after storm until now. Tree is good. The tree has been trimmed and everything. I dont know why it broke. It just wanted to go, i guess. You know what i mean . See how huge this tree is. Fortunately no one was injured when that limb came crashing down. It did nearly smash a parked car below. Downed power lines and falling trees keeping crewing in the south bay busy but theyre closely monitoring the gaud lee pay river. One of the many trouble spots today and youve seen quite a bit, youre standing in it, damion . This is the bike trail here. Im standing here because i put this cone here about just over an hour ago. You can see how much the water level has risen here along the banks. Some people actually try to jog or ride their bikes through this, but they had to close it for obvious reasons. Its been a busy day here in the south bay. Crews have to close this road in san jose because of a live down power line, one of many in the city. In fact, the san jose Fire Department was so busy today they needed assistance from the Fire Department to answer calls like this one from santa clara. On hillsdale avenue, part of a tree rested on the roof of a home. I didnt want to do anything right now with the chain saw because its too wet. Im afraid i might get hurt or slip or Something Like that. Reporter down the street, Good Samaritans ran across hillsdale avenue to remove frauns from a palm tree that were creating a driving hazard. The heavy rains also forced this gentleman to stop by the sandbag center. Just picking up sandbags to prevent water from getting into the entry way, front of our house is flooding, so it needed some sandbags. Reporter up springs, the river briskly flowed toward the bay, flooding the bike trail along the way. Can you pull this . These people look forward to the rising waters are these scientists from the San Francisco estuary institute. Theyre measuring mercury levels in the gaud lupe. The bigger the storm, the better your readings. Yeah. In a terrible sort of way we hope for a really big storm. Reporter and the big storm is what they got. This is a live picture. You can see how fast the river is moving. We are near the airport and highway 101. We saw an entire tree, kind of making its way through the middle of this river. If you can avoid this area, please do so. Its becoming quite dangerous. Were live in san jose. Damion, thank you. It was a soggy stroll along this creek trail this morning. Rising water drew closer to the jogging trail and bike trail. The fastmoving water broke loose a lot of debris and piled up along the creeks levies. So far the creek has stayed within its banks.

Talking about this storm, as long as we did right now as jeff is telling me, this is pretty much the peak of it right now. Yeah, exactly. Throughout a lot of bay area, weve been under this continuous rainfall for the past several hours and really from this point on, we should see things gradually taper off for us. Check out the stormranger, instagram and twitter. This has a Doppler Radar and equipped with a weather station to help give you a higher resolution of whats happening for improved accuracy. That is actually the Doppler Radar hoisted up on the back of the truck right there. As we get a look right now, 62 degrees out here at storm ranger. Temperatures will drop into the 50s, staying gusty and rainy, at least for the next three to five hours. And then again well start to see a break by late tonight. Lets go ahead and take you into the Doppler Radar scan. Again, its widespread coverage of rainfall. I think weve seen some of the heaviest widespread rainfall starting to move off towards the east, but thats little consolation here as the roadways continue to be so saturated any one heading out for the next couple of hours certainly needs to take it slow here with a lot of water coming up on the roads. The largest problems have been happening, of course, in the north bay. Thats why were still under a Flash Flood Warning until 3 00 p. M. , at least 3 00 p. M. From santa rosa down to petaluma thats where were finding a lot of streams, creeks and rivers overflowing their banks. Best advice, if you approach standing water, turn around and head the other direction. So, in terms of major rivers in the north bay were tracking, Russian River expected to hit flood stage, 37. 2 feet, late tonight into early tomorrow morning. Even though the rain may subside, again late tonight and tomorrow, river levels will likely still be rising. The napa river up to 19. 7 feet late tonight and into early tomorrow morning. And then youll see here on the radar, down towards the south bay, continuous rainfall here moving on in and that also has more flooding concerns with us. Down here towards morgan hill and gillroy, heavier pockets developing at the current moment. What i want to do is go ahead and look at some of the other concerns were seeing off to the south. The San Lorenzo River near felton hitting 20. 9 feet as we head throughout late tonight and also early monday morning. Getting close to major flood stage. So you know who you are if you live near the San Lorenzo River, you have to watch it extremely closely, evacuations may also be in place. Please, please follow the advice of those local officials. San franciscouito river. The gaud lupe river near highway 101 and we could hit 13. 1 feet again this evening. Now, joining us down here at the river, meteorologist rob. Rob, its also important to continue to watch this at least for the next couple of days. Reporter yeah. En though technically not at flood stage, i can tell you we are seeing some localized flooding along the guadelupe river. Probably another hour or so from reaching its crest. Fast moving and were still on the bike path that heads into San Jose International airport. Seeing all sorts of things, large tree trunks, debris moving very quickly from left to right across the screen as heavy rain falling into the Santa Cruz Mountains, heads down the watershed throughout the bay area. Take a quick look at the graphic, youll be able to see the rain in the southern end there, the Santa Cruz Mountains, dropping another gaud lupe watershed and fast forward three to four hours later, that begins to fill in the smaller creeks. Come back here live, we were here on this bike path and things were relatively dry. The water now is coming right over the curb, spilling over, flooding out the lower section where damion was reporting live just moments ago. As soon as were down with this live report, well get out of here because this water level continues to rise rather quickly along the gaud lupe river. Again, use caution. This river still forecast to rise another foot or two between now and 4 00 p. M. You want to use caution here along the bay area waterways. Jeff . Some great advice, rob. Again, it is called flash flooding for a reason. It happens in just instant of a second in some cases and if you think youre safe and close to the river banks, it could come up and certainly inundate your car or where youre standing, so stay away from the river banks. Stay away from those local creeks, rivers and streams. As we take a look right now, here is that Atmospheric River thats been fuelling this heavier rain fall throughout california. Well gradually see this move off towards the south over the next six hours again giving us a break. So i know thats what all of you want to know, when will this rainfall start to wind down. By 8 00 p. M. We still have rainfall with us, but once we hit 11 00 p. M. Tonight, you can see it breaking up across the north bay. Good for the large rivers to at least start to get a break. Then by 6 00 a. M. Tomorrow morning, we should begin to see just some spotty showers here throughout the bay area. So, again, some drying weather is on the way. Here is the extended forecast, little bit of rain at times on monday. A new storm, though, developing as we head into tuesdays forecast. River levels may be a concern all the way into wednesday of next week and this is the newest information now showing dry weather friday, saturday and also on sunday. So, that drying will get by the end of next week could save us from more of a catastrophic situation just because i think once that tuesday storm gets in here, well see things go back up again and it could be a repeat performance for a lot of folks in the north bay. So just hang on until thursday, friday, end of the week, thats when we get to dry out a little bit. You got it. Thanks, jeff. Well be right back. Creamy swirls of pure indulgence. Silky sifts of total transcendence. Tempting accents of sheer pleasure. Introducing unicorn whispers. This should be the name. Or something more like golden gold. Or maybe, mmmmmm mmhmm. But, with 20 of your daily fiber, its actually fiber one. So delicious, it should have another name. Well take a look outside as you heard there from meteorologist jeff, a flood watch is all over the bay area, including here to napa. Take a look here at this lane in napa county near san ha lena, this is where the road is under water completely, in fact, it has been this way for most of the day. You see the signage for the bridge and how high the river is crested at. The river is rushing into a nearby winery as we pan over at the winery right next to this road. Theyre dealing with a lot of water there at the base of those grapevines. They were joking that it would be good for the crops. One thing i just saw, a truck heading towards that flooded road turned around. Cant say why he did it, might have been because he didnt want to go into water he doesnt know the depth of. Smart idea. Smart idea. Always turn around. Another troublesome spot is the the Santa Cruz Mountains. Rick boone has been all day today. Last time we saw him, he had a rope around his waist keeping him out of the river. Rick . Reporter i do. Im a smart man listening to the residents. They said do that, thats what im doing at this point. Everything is coming down the river. We have trees, a lot of different things, articles from peoples homes backyards. Thats a huge tree that is going down the river right now. Thats a huge tree. That gives you an idea about the power of this water, how aggressive it is. Just about five minutes ago we heard this huge alarm in this area. That was a warning to get out of here. Residents say when they hear that flash flood honking horn, its an alert from the Emergency Services and they know they need to pack up or at least get an idea that they may need to move in another direction. Our shot last time i talked to you i was further down, now you know what im getting wet. Let me move up right now. And were going to continue to get out of here because theyre predicting this water could go in this direction as soon as possible. Were live in felton grove, rick boone, nbc area news. We are now on to safer ground. Stay safe out there, happy to hear that, rick. Hes right to see how swiftly that river is moving. Another update from jeff right after the break.
