But all eyes are on that other big sporting event you might have heard about over the weekend. The world cup final. We celebrate the fourth rooting for team usa at least we better be. Theyre going to go for their first title in 16 years and hoping to exact revenge upon japan after losing to them four years ago in 2011. Much much more on the big game live from vancouver coming up on the show this morning. Cannot wait for that. We begin with that Terror Threat this Holiday Weekend. Law enforcement all across america on high alert worried about possible attacks, especially from socalled lone wolves inspired by isis. Abcs Martha Raddatz is in washington with the latest on this good morning, martha. Reporter good morning, amy. Law enforcement really is in overdrive this morning, command centers set up in major cities special tactical teams already deployed after the unprecedented isis social Media Campaign encouraging supporters to attack wherever they are. And holidays with this much significance are sadly attractive targets and police truly are on edge. That false alarm of a shooting on thursday at the navy yard here in washington prompted a massive response. It is the lone wolf isis inspired terrorist who is most concerning. This year alone, 40 people with suspected ties to isis have been arrested in the u. S. Seven in just the last two weeks and those horrific attacks in france and on tourists in tunisia have heightened concerns overseas. The u. S. Military has now canceled fourth of july celebrations at Lakenheath Air base in england. But this is concerning for anyone heading out to those large holiday festivities over the weekend. What should people keep in mind . Reporter well authorities just want people here at home to be aware of the threat be smart. Be attentive, but celebrate nonetheless, amy. All right, Martha Raddatz, thank you. Dan. Permission to celebrate but 18,000 Law Enforcement agencies across america on alert.

If you have plans to travel or Outdoor Activities from northeast texas through most of arkansas northern alabama, mississippi, georgia, up through southern North Carolina thats where you could see damaging wind. With these storms come flash flooding. Look at this out of edmund oklahoma. Water rescues reported. Parts of oklahoma to tennessee and still have those flood warnings and advisory in southern missouri that expire north to south but a lot of rain possible in the southeast so thats going to be one of the trouble spots. Much more coming up including the whole country, fat july 4th forecast. A lot of people want to know the fireworks forecast. Thank you. To the shark surge. Fear at the beach because of the jump in attacks over the past month, some calling for the beaches in North Carolina to be shut down. Abcs phillip mena is in the outer banks with more. Good morning, phillip. Reporter amy, good morning. Today is the start of the busiest weekend of the year here, the site of the latest shark attack, these attacks are happening off the carolina coast at an alarming rate but why here and why now . This morning, high alert along the east coast. After 11 shark attacks off the shores of the carolinas this year most in just the last three weeks. Its pretty scary. I wouldnt go out there, not now. Reporter experts say the increase in attacks this year could be a combination of four factors. First, drought conditions. Limiting fresh water along the coast, the ocean water is saltier, which sharks like. Throw in warmer water than usual, add a surge of fish for food and factor in more people than usual at the beach and its a recipe for disaster. Sharks are drawn to the warm water. He do like the clear ocean water. But you also have a booming sea turtle population and they love sea turtles. Reporter the attacks so alarming some are calling for beach closures. But North Carolinas governor offering a warning instead. Recognize there are certain areas where were having these bites, so just use your common sense especially if youre in and around a fishing area. Reporter shark encounters havent just been limited to the carolina coast. Take a look at this video from chew on this. This fisherman off the florida coast inadvertently hooking a shark. The shark pulling away so forcefully he not only loses his reel he loses control of his boat capsizing. Then swims for his life scrambling to get away to the main fishing boat. This morning, and throughout the Holiday Weekend, there will be extra beach patrol rangers out here encouraging swimmers to stay close to the shore. Amy. All right, phillip mena thanks for that.

From florida this morning a very unlikely school reunion. A miami judge was overseeing a bond hearing for a burglary suspect when she recognized him as a classmate from middle school. Mr. Booth, i have a question for you. Yes, maam. Did you go to nautilus for middle school . Oh, my goodness. Oh, my goodness. Im sorry to see you there. I always wondered what happened to you, sir.

There is a big element of the Democratic Party that wants an alternative. Reporter many of his supporters tout him as the honest and authentic candidate. Hillary needs to consult with her focus group and get back to you in a couple of weeks. Its about time that someone actually stood that we know is on our side. Reporter just for perspective when president obama was running for his first term as president almost three months into his candidacy he had 100,000 donors. Sanders just two months in has 250,000, so just a few weeks ago he seemed like a long shot. He still may be but there is a Sanders Movement right now. Interesting story. Linsey, thank you so much.
