At this time but as you noted with a focus on those socalled lone wolf attacks, those individuals ohio may simply be inspired by eyes circumstance the dangers now are more complex and more unpredictable than ever. With america ready for the fourth of july today, officials are focused old keeping the celebrations safe. This year heightened concern, but no specific or credible threat.

All right, peter, thank you very much. Of course everybody know what is the weather is going to be like for the Holiday Weekend. Dillon could be a stormy one for millions. It could and i have been saying it could be nice in the northeast, that could change a little bit, just a couple of showers, but it was in tennessee yesterday we saw some of our heaviest storms. We ended up with a lot of tree damage because of damaging wind gusts and also a possible tornado. This is right near nashville. This tree falling right on a car, falling across the roads, downing power lines. Some were without power because of these storms yesterday. This is a stalled from the that is sitting right through the Tennessee River valley and theres a possibility we could see more strong storms again today, although with each day, we are losing the threat of Severe Weather and it looks more like we will just see some rain. A couple of areas of low pressure and within these heavier downpours, we could end up with some flash flooding there is a flash flood warping here in red where some of these storms are just training over the same area. And we could end up with a couple inches of rain. We do have a slight risk from oklahoma right back into the carolinas, where we could see, again, large hail damaging wind gusts and isolated tornado is possible be brief and its not going to be a tornado outbreak by any means but there are about 25 Million People in that atrisk area. As we go through the day today, we are still going to see these showers and storms develop through tennessee. Watch as this area of low pressure creeps a little bit further into the midatlantic. It is not looking like a washout, but just keep in mind saturday afternoon, we could see a couple of spotty showers from d. C. Up through new york city. But the main rainy areas will be back through arkansas into mississippi through alabama and up into atlanta, too. So for your fourth of july forecast its this area in green where we could see some of our spotty showers. Out in the southwest, too, it is still going to be hot with a few isolated thunderstorms and the heat is just exceptional in the pacific northwest. All right, dylan, thank you very much. See what happens around the country there. But it is not the storms but sharks that are causing concerns along the North Carolina coast.
