this landmark. they are daunting for the tallest building in the capitol. >> how do you reenforce this so they could withstand another earthquake? we are 60 some-odd seats. >> reporter: but the team, they have great faith that it will be done. on top the national cathedral, surae chinn, 9news now. >> that money is nice, but remember those repairs are expected to take ten years. they have received nearly $80 million before today. but they needed a historic preservation work bringing a total to $54 million needed to completely restore the hand mark. they felt be more than 100 aftershocks in the last year. most of those have been centered in and around virginia. they were in town there today where people are still trying to recover. >> reporter: a year ago toda the world seemed to be tumbling down around them. his store, it is miller's

>> i know the community is sad because many of us like me came back here to live and we went to that high school. >> reporter: students have gotten used to the buildings, which will be in place until a new school is built in about three years. the federal state and private donations, they have helped the county schools. >> i'm just amazed every day that someone would like to help us. >> reporter: two miles down the street it is the opposite feeling at miller's market. >> i'm so upset. >> reporter: in virginia, peggy fox, 9news now. >> so where were you exactly when that earthquake hit? join in on the conversations on our facebook page and check out our photo gallery at wusa9.com. last year's earthquake gave disaster officials a glaring message. east coast residence need to be prepared for earthquakes as their west coast friends. >> we have a danger in earthquakes that we need to be% be more and more in facted about. if you cannot predict when they

occurred or the size and the magnitude, at least you can prepare for them. >> they are planned for much of the east coast. this will be the first time that d.c., maryland, virginia, that they will all take part in the stop, drop, hold exercise that will be already done in other parts of the country. and another disaster that you can always prepare for is a hurricane. tonight, tropical storm isaac is moving west. topper is tracking the storm from the weather center. >> reporter: yeah well it is still a tropical storm that winds are barely a tropical storm 30 miles per hour or higher with the tropical storm that they have 40 miles per hour winds. let me show you the track here. that we do have the hurricane warnings in effect for the southeast and all the coast of haiti and the tropical storm warning is in effect for the north coast of the d.r. this is a track for the hurricane center that they will need to take on sunday and monday and tuesday and the keys and end up on the west side of florida. right now it's about 255 miles southeast in the d.r.

so again if that is exactly where they would need to take the track. the highest winds and most of the damage would stay offshore, but too early to set this thing in stone as we'll watch it for you carefully. it will become a category one hurricane by late sunday night and monday as it goes back to the gulf of be mexico. >> they will be closely watching it. thank you very much. freedom fight. a judge decides the fate of the virginia veteran detained over their violent facebook post. find out if he could be once again a free man. that's at 7:00. >> we'll see you then. still to come in this half hour of 9news that he was drinking before getting behind the wheel of the motor boat that collided with the other sending about five other people to the hospital. but first, new details about that deadly derailment in the city. we're back in 90 seconds.

old was killed when he was hit by a trash truck backing out of the same one. he is calling on the d.c. department of transportation to look for another way to manage traffic in that area. >> and some fans may have come away with more on the agony of defeat. the maryland department of health says they may have been exposed to rabieses. a bat apparently landed on someone sitting in the .500 section of the bank stadium last friday night. the health department is concern that anyone who touched that bat may have been exposed to rabies. some of us will be fine before you dash out for work. but it's a different story here today. the education secretary arnie duncan expressed to make sure that free break fast will be available for every child who needs it. >> and their stomachs are growling. it will be pretty hard to compensate as we will have over

10 million children. and they are not receiving them as we need to close up the gap. >> a new study shows that three out of five teachers in maryland say that they have children that will come to class hungry as say they'd that it is extremely important to academic success and 15% of those teachers will buy food for their students every week. and still ahead, the flooding was caught on tape. find out how the waters rose quickly with little warning.

they agree. we can no longer see that there and there is at least something saying that we'll go into miami or point a little further south over to the keys, into the gulf of mexico. it is still not set in stone by any means, but there are indications though that it will become a hurricane once again as you need to get into the gulf of mexico, losing their punch for cuba. right now a live look outside. it is fantastic outside. i mean a great night to do anything. 85 degrees. comfortable humidity. pretty good deal. the pressure is steady at 30.11 inches of mercury. live doppler 9000. most of the showers are out. they are getting hammered with an inch and a half of rain so far and another inch on the way as you can see the red, that will be the rain fall rates in an hour and just to the south. but lighter. now, we just had this pop up literally in the last 20 minutes, out towards here and paris. and that is actually working their way here southward across 50 and becoming a little

stronger. so the isolated showers will be possible tonight and for the most part a nice evening. don't change your plans if you have the outdoor plans. temperatures, 83 here and also in fairfax, very comforble. 84 in arlington and 86 at college park. but again relative humidity will be very comfortable. isolated showers and storms tonight. you can still walk the dog. open up the windows. i mean temperatures will be in the 60s in most places. a strong finish for the week tomorrow and then well, we'll be going downhill here. and it was light by morning. partly cloudy. limit your time outdoors please. partly cloudy and warm. and the next three days, and a slight chance of the showers tomorrow. no big deal.
