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: and then a sample of that water has to be sent to another lab that has to sign off that could take about 18 hours we're told to make all that happen before the water restriction disease be lifted. again, they will be in place until noon on saturday for the rockville public works water customers in the city of rockville, about 48,000 people. as far as what caused the break here yesterday, well, right now the public works director says he doesn't really know. they found some corrosion on the broken pipe. but at this point they just know that it broke. they'll send the pipe off to be tested as

another year. 92 currently in washington. there actually are a couple of lonely thundershowers out there. heat index values remain in the high 90s, and right around the 100-degree mark. right now

to try to get it done this evening. >> reporter: mo abdi owns a clothing store. >> some short pants, like went out, and i lost money. >> reporter: you have no power? >> no power. >> reporter: and you've had no power? >> almost an hour and a half. >> reporter: and you're being told? >> nobody know anything. an emergency or something going on. >> reporter: d.c. councilmember tommy wells who 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 veterinarians are treating more dogs and cats with signs of heatstroke. doctors at the alexandria animal hospital say many of the cases they have seen this week are quite severe. >> certainly there is

than $50,000 in overdues late fees and attorneys costs. brown is chair of the council's development and is slated to become the next council chair. now here is chuck with the weather. >> hey there, 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 right, thanks. >> he does, indeed. the bulls are still in the hunt too. >> indeed they are. bruce beck, thank you so much, bruce. chilling surveillance video captures a fairfax teen just minutes

after 1:phone this afternoon. >> the driver suffered some injuries, but is expected to be okay. the accident backed up traffic on the beltway several miles into montgomery county. and again, here are live pictures from chopper 4. >> a long backup there. >> sure is. well, when we think about stroke patients, we typically think about the elderly. >> but, you know, it's actually a condition that can 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 car
