Yes, flooding just one more aspect of these storms adding insult to injury in many cases. 170 storm reports yesterday. We mentioned the tornadoes, but bigtime hail and Straight Line winds doing significant damage, also and heavy rains this morning on the radar showing up across dallas and North Central texas that will slowly move to the east. The Severe Weather threat today will be targeted in minnesota and had a half of does yesterday so they could get two days in a row with twisters and extends to the Canadian Border almost down to the gulf of mexico. Rain is the other issue. An additional 1 to 3 inches potentially across parts of texas, an area that does not need any more rain. Paula. Great to check in with you. Boy, did we see it in maryland. Nasty weather, heavy rain and a sloppy track could not stop Kentucky Derby winner american pharaoh from dominating at the preakness, the powerful colt now has a shot at the first triple crown in almost 40 years, and abcs Mara Schiavocampo has the highlights of the big race. Good morning, mara. Reporter good morning, paula. That horse did it in far from ideal conditions. The weather so bad at one point spectators had to be evacuated.

The 3yearold colt is owned by an egyptian billionaire turned stable owner, who could soon become the first horse since affirmed in 1978 to win the triple crown. Now, American Pharoah is only the Kentucky Derby and preakness. The Belmont Stakes is on june 6th. I have to ask you looking at those conditions they were atrocious but a member of American Pharoahs team said that he had to run through a river to win, was it safe . It could be safer than a hard surface. Which is more likely to lead to ininjuries. American pharoahs owner actually wanted wet conditions because he has some experience with that. Whereas some of the other horses were totally spooked by it. In this case it worked for him. I think the horses that favor those conditions are called mudders. Good to know. Tough mudders. Tough mudders, thats right. Thanks, mara. Thanks, guys. Were going to switch gears now, head overseas to the new information coming out about that raid by u. S.

I think theres a good chance of thathaing today. As we go into the evening, those storms press east toward chicago, although chicago a lesser risk of se
