'tis the season to be buying and returning merchandise, and that doesn't always end so well. i'm consumer investigator chris chmura, "nbc bay area responds," next.

welcome back, everyone. taking a live look outside, wasn't the rain over the bay area refreshing? it was so needed to calm down so much of that smoke and just clean things up, and a nice view from the city by the bay this morning. already lights illuminatinillum 'tis the christmas season! let's kick off the song. >> thanksgiving a distant memory. >> way back before people were buying things for christmas. >> i do have a lot of leftover pie i must say.

>> we have a lot to talk about in weather, good morning. >> it is but things got a little bit better considering the winds peaked last night. the wind advisory was canceled for the north bay but i want to show you this image of satellite radar. it gives you a good idea of the second storm system that made its way in last night. it will impact us all day. here it is, kind of bringing in all of this moisture, but we have our very own storm ranger which is able to scan kind of at a lower elevation and gives us a better picture of what we're seeing right now on the ground. this is what it looks like using our storm ranger. we've got some showers moving through santa rosa right now, novato, concord and where it's green it means it's not as heavy as rainfall. if it was yellow or red that indicates the heavier downpours but all in all, if i move this around throughout the bay area, could you see hayward getting some showers, oakland getting showers, down through san mateo, but we have some spots that are still pretty dry, not pretty typical spot for rain, considering the rain showers for

san jose. any time we get rain in the south bay, we get excited but san jose don't expect to be dry all day. we still have the possibility of seeing some periods of on and off again showers as all of that moisture you saw just off the coast continues to trek on in. right now the -- sunnyvale not getting showers. couple of spotty showers here and there. overall, we are going to be seeing this rain continue all day long into possibly early saturday morning. our greatest areas for concern are the flash flood watches and the burn scars where there's potential for debris flow near the mendocino complex and camp fire. for sierra the heaviest of the snowfall six inches last night, some parts expecting an additional four to eight inches tonight and possibly into the weekend. as we head in towards tonight, we're going to keep the showers a few a.m. showers expected into early saturday morning, but i also want to you look ahead towards monday and into tuesday,

because next tuesday, we're tracking another system expected to make its way in, so here comes the rainy season, mike. >> all right, well make sure we're ready, make sure that you check those windshield wipers before you head out on any trips and the tire treads as well. right now the traffic flow very light. we have a couple of smaller crashes over castro valley and also in oakland. no major interruptions to these speed sensors, that's a great drive. be careful, the slick conditions continue. i saw say spinout 880, off-ramp at brokaw, two tow trucks had to get by on the shoulder. just fine toward the bay bridge, contra costa county no delays behind me. the road weather index shows you the blue, ponding and puddling through rio vista but the bridge is operating no problem and so are the rest of your bridges throughout the north bay and toward the east bay. heading into the north bay from the east bay, the richmond-san rafael bridge, wait for a second, yeah, no one's coming. that may be the case for the early morning commute, all around the bay, even the bay bridge we have a light volume of traffic.

the rain falls a little bit of couple drops here and there. the water kicking up will make visibility tough from time to time, and do watch for the flooding or at least some of the lanes, if you stay to the middle lanes of the freeway you have a better chance of keeping traction. back to you. >> thank you, mike. it is 4:48 right now. this holiday weekend, striking hotel workers not taking a break. marriott hotel workers have been on strike for 50 days, 2,500 employees in san francisco. marriott and its employees were not able to reach a deal this week. workers are prepared to be on strike as long as it takes to get a fair contract. workers reached contract agreements in oakland earlier this month. seeing as the holiday holiday shopping season is here we asked consumer investigator chris chmura for a quick refresher. >> we are not kidding around when we say we respond to lots

of return hassles. we helped julie in oakland, andrew in sunnyvale, erin in san francisco, julie in san jose, jim in napa, greg in san mateo, lots of others. here's the thing. even though most stores have return policies, they are not written into state law. in fact, the attorney general says don't assume a store will allow you to return an item if you change your mind. all right, let's do some q&a real quick here. can a store charge a restocking fee? the answer is yes. can they only allow exchanges not refunds? also yes. can they give you store credit instead of cash? yes. and can they require you to have an original receipt for a refund? also yes. you see a trend there? you need to figure out the return policy before you swipe your credit card. some stores will loosen their return policies around the holidays but not all and they don't have to. so please, check the rules. they should be posted in writing at the service desk, or printed on the back of your receipt. if you have trouble, let us

know, go to nbcbayarea.com/responds or call us 888-996-tips. >> do you sometimes lose your receipt, yes. he forgot that one. get ready to sing -- ♪ you're a mean one, mr. grinch ♪ the beloved revivaled achristmas crumudgeon is right here on nbc bay area, a new cartoon "trolls holiday" will also follow. >> there have been so many remakes of that. i know there's a new one. this is a classic, the one that started it all. >> my kids love it. that's it, kicking off the season, here we go. coming up on "today in the bay," the rain is here, so, too, the wind. >> as we've been mentioning we're under the microclimate weather alert as the storm is lingering. we'll track the rain with the help of nbc bay area storm ranger scanning the skies. look at the green radar out there, all that rain. happening now at 4:50, to

the most trending video on youtube this hour, the first trailer of "the lion king" live action remake roaring back to live. disney debuted it thanksgiving day, shows the iconic images from the 1994 movie and the voice of james earl jones who will reprise his the mufasa boys, the narrator of the flick.

i saw some car spinouts out there, take care and caution before you head out the door. 4:53 right now. as we experienced all season, destructive wildfires threatening homes and lives in california. >> but what if there were a way to stop them from happening? more than the dream of two south bay teenagers is something they've been working on for years, garvin thomas shares the story in this morning's "bay area proud." >> reporter: faced with something as powerful as an out of control wildfire, it is easy to feel powerless to do anything about it. >> we used to have the learning rate of -- >> reporter: turns out not if you're these high school adviceors, no relation to each other. they are two students with a passion for engineering and the desire to do good. >> why don't we have a proactive measure that can prevent this destruction from happening? >> reporter: the answer to that

question is what aditiya is carrying in his hands. for the past two and a half years, these two have been working on a smart wildfire sensor. the idea very simply put is to use photography to determine just how much fuel for a wi wildfire like dry grass or dead trees there is in a certain location and combine it with wind, temperature and humidity to pinpoint where a wildfire is most likely to happen. >> we thought why not use the technology that we have in our generation in order to solve something that terrifies people so frequently. >> reporter: the prototype that aditiya and sunjana have been working on in this cupertino park uses a stationary cam camera, but their idea, they hope, is about to reach new tights by usiing drones and machine learning they anticipate

to be able to cover huge swathes of territory, something impossible using the current manual methods. their work is so promising cal fire's research and development branch has been in touch and aditya recently made a presentation at google whose technology is keen to the effort. >> it feels satisfying to know the number of lives you're actually helping. that's what's the fun part about it, knowing that we make a difference. >> garvin thomas reporting there. well, thanksgiving's over so let's turn to christmas, if you haven't already. >> 36 million americans will take part in some kind of white elephant gift exchange, maybe you call it dirty santa. >> i never heard that. >> i never have either. >> it's an east coast thing. >> must be. online retailer zulily wanted to know how everyone felt about the recent trends. 35% say what they love most of white elephant is spending times

with friends and family. 24% love the gifts. >> what? >> 24% walking away with something unexpected and americans are spending $22 billion. >> the first time i was exposed to that, it took forever to understand the rules. i get it and it's great fun. it's fun. >> it's better when you get something cool. when you don't, not so much. >> that's how the game goes. >> regift it for next year. come up on "today in the bay," president trump doubling down on the new feud, the harsh words he has for the chief justice of the supreme court. are you also buying something cool for the exchange? >> of course! >> i usually buy something cool, at least i think i do. >> you got to buy something you'd want at least, right? >> that's true, laura, a good point. what else is cool, all the green on the map, this is what we've been waiting for and it made its arrival and we're continuing to track that using our storm ranger. coming up in a bit, i'll talk about what's going on, where watches are still in effect, how long the rain will last and we'll track the time line as it

heads into your city, coming up. >> i show you on the roads right here, this is the golden gate bridge, that's not interstate 80. i'll correct that sign but that's about the only thing wrong with this drive right now. i'll show you more coming up. the warning as urban scientists and journalists issue being climate change. lot more ahead. you're watching "today in the bay." this little home of mine,
