brown. >> you can't water your grass and stuff like that. you can see the grass turn brown already. it's from the heat. >> reporter: that's thanks to this torrent of water that climbed 100 feet into the sky. rockville's main water line ruptured, two million gallons of water lost in a geyser active for six hours. >> we have two broken sections. it happened right near the joint. two sections have to be replaced. >> reporter: crews spent tuesday digging up the old cracked pipes and around 1 made the first attempt to install the new line. problems forced crews to bring in new parts and begin again. >> we should at least try. always forcing people to restrict water, but we can at least try to help out the whole community. >> reporter: rockville residents are temporarily getting water from wssc. at the same time, 75% of the city's residents, perhaps some 48,000 people, are being told they have to conserve water until noon on saturday, meaning no water use outside, and less use inside. >> making sure that dish washer is full loads. making sure they take shorter showers. less flushes of the toilet. >> reporter: even after the new pipes are in place, they can't immediately lift water restrictions. >> we have to chlorinate it, super chlorinate it to make sure there is no bacteria in it. we have to flush that out and refill it with fresh water. and we have to test it. >> reporter:

represents this ward is on the scene. >> for the businesses to be hit is very frustrating. and, you know, we just have to -- we can't change that. and we need pepco to be honest about the times, when this can come back on, and what we can expect, because we have to be able to plan around it. and so i know that pepco is doing their best, but they really messed up on their times for the last outage. they kept saying it was going to come back on, people would make their plans that, and then it didn't happen. >> reporter: now pepco is saying that they hope to have power restored to the businesses here in the 1300 block of h street northeast tonight. as you see a crew that just arrived behind me is checking another hole underground. they say with the heat, this kind of thing could happen all around the city throughout the summer. but pepco says it is ready. we're live on the scene in northeast washington. back to you in the studio. >> all right, chris gordon, thank you, chris. local

pat and jim. a very sultry day to be outside once again today. but we did not make 100 degrees. that's a nice change of pace. only 95 for an official high temperature so far today there is a look at our hazy color of gray skies outside as you look around today. certainly hardly a day meant to be in the greta out of doors. temperature right now at national airport is steamy 92 degrees. the dew point temperature at 69. any time that number hovers near 70 degrees, it feels miserably uncomfortable outside. today's heat index bears that out. 98 our current heat index. thankfully, though, that wind out of the southeast at 10 to 15 miles per hour now has really brought some cooling influences, especially for the folks lucky enough to live right up alongside the chesapeake bay and out on to the eastern shore. they have really caught quite a break. here in the urban areas around town, temperatures remain quite warm. on the radar, a couple of thunderstorms. isolated and far spread as they may be, still some isolated thundershowers out there. we'll zoom in for you. this one right here in frederick county, maryland, moving just down to the west of the downtown areas of frederick. came through thurmont, maryland about an hour ago. the weather watch said his temperature dropped from 98 to 73 degrees. so a 25 degree temperature drop. and it's picked up just under 2 inches of rain in thurmont, maryland. so yes indeed, if you can get underneath one of these, it's a pretty good little soaker. you folk in birkittsville, you're in the path of the storm. and upper loudon county, it may live long enough to get parts of upper loudon county wet as well. developing across parts of southern fauquier county, it's starting to fade away. unfortunately for those around town, no cooling showers whatsoever. our future scan here shows that storm continuing to further and further down to the south. you can see the very widely scattered thundershowers indeed today. a little better coverage as you get down to the south of richmond and way back across the parts of the ohio valley. temperatures around here for now. heat indexes will remain in the upper 90s to near 100 as the dew points continue to hover around the 70-degree mark. i'll have a complete check of your seven-day forecast coming up here in just a couple more minutes. for now continue to expect to be warm and humid with rain chances increasing. more later. >> thank you, chuck. it's a rally on wall street today. stock prices up for the third straight day. all three indices rose. amanda drury joins us live from cnbc headquarters. what is behind the market gains today? >> well, this is a really cheered. first a drop in applications for unemployment benefits. that's great do see we've got some progress on the job front. and also some solid sales from a handful of large retailers. the warm weather coupled with holiday sales helped a number of retailers see better than expected sales for the month of june. for example, department stars like jcpenney, they saw sales up 4 1/2%. sales at nordstrom, they jumped 14%. the gap was among several retailers that did see either modest sales or flat sales. now, however, as a by-product of the still weak jobs market, the federal reserve came out saying that consumer credit plunged by a much larger than expected $9.1 billion in may. it is the fourth straight month that consumer borrowing has declined. it seems to be one step forward and one step back as far as the economy is concerned. >> amanda, we see mortgage rates continuing to fall. but that doesn't seem to be helping the economy. so why is that? >> you know, it's really ironic, isn't it? we got some numbers from freddie mac. they say the average rate slipped to 4.57% last week. so why isn't it helping? well, there are concerns that the housing industry may not benefit from these record low rates because many home buyers, number one, they're already taking advantage of the low rates, or they're not qualifying for new mortgages. and also remember, a lot of purchasing were brought forward by the home buyers tax credit, and we all know that expired at the end of april. jim? >> cnbc's amanda drury, live from cnbc headquarters. amanda, thank you. pat? >> well, it is d-day. tonight at 9:00, lebron james will finally tell us where he plans to establish his basketball kingdom. it's a move that is sure to boost the economy in the city of his choice. wnbc's bruce beck joins us from greenwich, connecticut with the announcement and will tell what's is going to happen tonight. bruce? >> reporter: pat, it's a circus out here there are television trucks everywhere. tv and radio reporters, newspaper write wherers, it's one of the biggest scene i've ever seen. compared to an all-star game, it's unbelievable. we're outside the greenwich boys and girls club where lebron is making the announcement tonight. and we're only 33 miles from new york city. so the knicks hope that is a good omen, that they can get the king, lebron james, the two-time league mvp, the six-time all star. but right now the miami heat are considered the favorite, with the cleveland cavaliers still in the hunt. so pat, i don't know what he is going to do. but i know everyone is still hoping that he comes to their team, their city. >> and we understand the president wants him to go to chicago? all

strike anyone at any age. doreen gentzler is here now with news for your health. doreen? >> reporter: that's absolutely right. tonight we're going to meet a woman you might know. she is bob ehrlich's newly announced running mate in the race. and at the age of 43, mary cane suffered a stroke. >> i was paralyzed. half of my body was completely paralyzed. >> reporter: it was about 4:00 a.m. on a summer sunday when mary kane woke up and realized she couldn't move. >> it was looking at your hand and wanting to feel something there. you can look at it, and nothing would happen. >> reporter: kane was having a stroke. >> this doesn't happen to young people. especially 43-year-olds. >> reporter: doctors told her she would have to stay in the intensive care unit at suburban hospital for at least a week, and then move to a rehabilitation center. but kane didn't have time for that. she was about to be sworn in as maryland's secretary of state. >> and that wasn't going to happen if i was going to rehabilitation center. >> reporter: while her case might seem unusual because of her age, doctors say strokes off happen to younger people. in fact, nearly 30% of all strokes occur in people younger than age 65, and most of the time the younger patients are women. >> it's definitely more common in those older than 65 because you have more of the pathology that leads to stroke, but it can happen also in kids and it can happen in young adults or late teenagers. >> reporter: a stroke happens when either a blood vessel is blocked or bursts and blood can't get to the brain. that causes the brain to stop working, and cells to start dying. depending on which area of the brain is affected, patients will have different symptoms, including vision problems, numbness, or weakness on one side of the body, difficulty talking, and sudden severe headache. dr. jose marino is a vascular neurologist at suburban hospital. >> there are very many reasons for a stroke. ischemic strokes where blood flow is interrupted, when there is a clot that stops blood flow there are many causes. >> reporter: stroke causes can include high blood pressure, high cholesterol and diabetes. those are the most common risk factors, and dr. marino says those conditions can all be prevented. but once you have a stroke, time is of the essence. patients have a three-hour window to get clot-busting medications to prevent lasting brain damage. >> the treatments have to be started as soon as possible after symptoms. because the longer the time involves, the more brain cells die. >> reporter: in mary kane's case, doctor says her stroke was unavoidable. an mri showed that a tear in her carotid artery caused the clot that stopped blood flow to her brain. nobody knows how or why the vessel ripped open, luckily she got treatment quickly, and in four days she was out of the hospital with all her movement back. >> you become much more grateful for your health. and know that things can happen like that. >> the important thing to remember here, act quickly if there is any chance you think you might be having a stroke. you need to get to the hospital as soon as possible. jim and pat, that's true if you're 62 or 42 or 22. it can happen to anyone. >> all right. thanks, doreen. attacked in annandale. several women were targeted. now there is news of an arrest, and police tell us they didn't have to go far to

triple? >> right. it's a big number, and it hasn't been a good week. >> we'll quick, a little clarification so folks know the difference between code red, code orange. >> code orange -- both are

degree stronger. it's unhealthy for everyone. and it's better if you exercise outside, to do it very early in the morning or do it indoors. >> you pick up any health magazine or any magazine that has to do with the environment, you know the number of cases of asthma are increasing. >> that's right. >> for everybody. kids also. >> that's right. >> what can we do to improve the quality of our air,

things were taken to this extreme when they really shouldn't have been. >> reporter: the state also dropped the charges against another student, steven harvey. but the case against university of maryland senior brandon johnson did go to trial. an officer testified in court that johnson flipped police the finger and would not cooperate with orders. while there was no video of this arrest, the judge decided to acquit johnson because there wasn't enough evidence. >> i feel really relieved. i feel that a huge weight has been lifted off my shoulders, and things are actually right again. >> somebody should be asking the question how can you have a police department which goes out and charges 28 college students and there is no basis for these charges? somebody has to ask that question. what is going on? >> reporter: john schriffen, news4. tonight the fairfax county school board will vote on whether or not to close an elementary school. students and parents had been lobbying to keep clifton elementary open. the 58-year-old institution is in danger of closing because of contaminated water wells and because the building is just too small. officials estimate the renovations would cost about $11 million. parents say the building is a landmark and should stay open. a company that runs duck tours across the country has now suspended the tours indefinitely. this move follows an accident yesterday up in philadelphia. authorities are not optimistic about finding two hungarian tourists alive. they are still missing tonight after a disabled duck tour boat collided with a barge and sank in the delaware river. rescue crews called off dive teams today. they say the water is too murky and turbulent to look inside the sunken boat. >> it is laying upright on its wheels there could be bodies inside. we're not sure. >> the missing hungarian tourists are a 16-year-old girl and a 20-year-old man. the tour was operated by the georgia-based company ride the ducks. it again has suspended tours nationwide. well, tonight is the night we've all been waiting for. >> we are ticking down indeed. dan? >> guys, you know lebron james notwithstanding, it's been an interesting week in the world of sports. and have it all for you in one nice little nutshell we like to call "in case you missed it." from baseball to soccer, the funny and the ugly. here we go. in case you missed it, some great catches in baseball this past week, starting with the mets at city field. check it out. the mets fan uses his hat to haul it in. now that's getting it done. how about in texas. the indians sin su chu, shoves the kid out of the way and gets the ball. not very nice, but there is a happy ending. the kid wins fan of the game, and the guy in the yellow shirt decides to give him a ball. the kid says you know what? that's kind of nice. i think hi i might give you this shirt as well. the angels' torii hunterer isn't an all star. the chicago right fielder making the diving catch on the warning track to rob hunter of extra bases. not to be outdone, quinton's white sox teammate eric with the behind-the-back stab on the mound. then he throws out alberto at first. think it's easy? ask the angels jered weaver. he couldn't even keep his feet when pitching against the white sox. more embarrassing than it is painful i would say. back in texas, the indians' matt laporta got quite a headache at first base. elvis andres with the grounder to short. nails laporte in the back of the head as he runs by. the indians infielder knocked out. play keeps going. by the time laporta comes to, the shut-out is over, but he is ready to keep going. sunday, the netherlands will play for the world cup title thanks to this shout by giovanni van brock horst. just inside the post, and think. two inches in another direction, and we might have a different final on sunday. same thing for germany advancing to the game. had the ref gotten things right in their game against england last week when frank lampard scored the tying goal, it might be the english, not the germans playing tomorrow. all england got was an apology a couple days later while germany got the right to move on. you don't see umpires smile often, but even c.b. buckner had to grin after he punched out tigers's johnny damon at the plate. there are only two strikes so he wasn't going anywhere. in case you missed it, you have now seen it all. >> i like that damon reaction. he is what are you talking about? the big news is lebron, and we're going to have a lot more on that coming up. and we're going to visit each of the cities. we talk to our nbc brothers and sisters around the horn, and they're going to report from each of those spots for us. >> your money is a little it on miami, right? >> a little bit. it could be new york, i don't know. >> you don't want to make a prediction. >> that's the fun of it. >> one of those three. >> thank you, dan. >> stay tuned. >> the game going until 9:00. it's the cutting edge in surgery. how 3-d technology is being used by doctors to treat patients. >> get the news you need to know while you're on the go with our breaking news text alerts. all you have to do is text d.c. breaking t you're watching "news4 at 5." >> hospitals are getting more high technology, and that makes surgeries less invasive. >> some of the latest gadgets include 3-d technology for spinal patients. nbc's monica dean went inside one operating room to see how this 3-d technology works in action. >> reporter: it almost looks like something out of a sci-fi movie, but this is the o-arm, a machine that is changing spinal surgery. >> it's incredible. >> reporter: patient blake miller has suffered from excruciating back pain for a decade. he has been unable to work and challenged caring for his three young children alone. the o-arm played a key role in his surgery nine days ago. >> i don't have pain now compared to the last ten years. >> reporter: here is how it works. the o-arm takes a 360-degree x-ray of the patient. here we're using a mannequin. the pictures are sent to the computer that produces a 3-d image of the patient's anatomy. >> this is only a few millimeters to where the nerve is going to be. >> reporter: the computer then tracks the instrument the doctor is using, showing on the screen exactly where the tool is going in the patient's spine. >> we can actually take that information and navigate with it. so it gives us a road map. >> reporter: a 3-d road map that enhances safety and accuracy of even the most complex surgery, helping avoid damage to other areas of the body. and once the surgery is done, the o-arm can act as a mobile ct scanner, allowing the doctor to instantly check his procedure for accuracy, reducing the likelihood of follow-up procedures. a surgeon says incision site is greatly reduced, and patients are healing faster. >> now they're coming up, standing up. age 60, walking around saying i'm ready to go home, doc. it's remarkable difference. >> reporter: blake miller says he climbed the stairs the first day. he is looking forward to living life again. >> my kids won't have to wait for me. i'm going to be in front of them, for once. >> and that's it for "news4 at 5." >> stay right there. news4 at 6 begins right now. >> you're watching nbc 4, washington's news leader. now live in hd, this is news4 at 6. >> crews are trying to fix a massive water main break, but it looks like it will stretch into the weekend. a key piece of evidence is missing in the murder case involving a university of virginia lacrosse player. and a spy swap with the russians. some of theirs for some of ours. but we begin tonight with an exclusive news4 report. good evening. tom sherwood joins us with
