After deadly tornadoes and floods have ravaged communities for weeks, the storm-weary central United States is getting some relief as the threat shifts toward the East Coast on Thursday.The U.S. has endured damaging tornadoes somewhere every day for the past 13 days.Several deaths have been blamed on flooding and severe weather, including one each in Arkansas, Kentucky and Ohio; three in Missouri and six in Oklahoma, authorities said.Thursday, severe thunderstorms could produce damaging wind gusts, hail and tornadoes across southeastern Pennsylvania, northeast Maryland, north Delaware and southwest New Jersey, CNN meteorologist Derek Van Dam said.About 26 million people are under a slight risk of severe weather and 48 million are under marginal threat, CNN meteorologist Michael Guy said.Tornadoes break a recordIf no tornadoes are reported Thursday, the nation will breathe a collective sigh of relief. On Wednesday alone, there were 24 tornado reports, Guy said.The last day without a tornado was May 15, making Wednesday the 14th consecutive day that the continental US saw a tornado touchdown.So far this year, there have been at least 1162

American Airlines plans to cancel flights well into April because of the Boeing 737 Max grounding.American, the world's largest airline, said Sunday it is canceling about 90 flights a day out through April 24. Before Sunday's announcement, American had only canceled flights through March 28.The airline is hopeful that that the 737 Max planes will be flying again soon, but said it is canceling flights about a month out as it waits for word from the Federal Aviation Administration."Canceling in advance provides additional availability and rebooking options for our customers," said the statement from American.The global fleet of 371 of the 737 Max jets was grounded indefinitely on March 13 after two of the planes had fatal crashes. A Lion Air flight crashed in October and an Ethiopian Airlines flight crashed on March 10.The causes of the crashes have yet to be determined but the focus has been on an automatic safety feature which may have forced the nose of each plane lower when it incorrectly believed the plane was in danger of going into a stall.Boeing and the FAA said they are working on an upgrade of its software to deal with that safety feature. Boeing said at the time of the grounding that it expected that update to be available "within weeks."American has 24 of the 737 Max 8 jets. But not every flight which had been scheduled to have a 737 Max has been canceled. American said it has rearranged its schedule to use other aircraft to complete some of those flights."We have balanced [cancellations] across our system," said the airline. It said both international and domestic flights are affected. "We will vary by day as we look to impact the fewest number of customers."American operates 3,300 flights its mainline system daily on average, and another 3,400 through regional carriers and partner airlines.Other carriers are not canceling nearly that far out.Southwest Airlines, which has 34 737 Max jets, said it is only canceling five days out at this point. It said it is also trying to rework the schedule to affect the fewest possible number of customers. 2099

American rock climber Brad Gobright has died after a fall in northern Mexico.The incident happened Wednesday at Sendero Luminoso in El Potrero Chico, the nation's civil protection agency said. Gobright, 31, of Orange County, California, was with a climbing partner when he fell nearly 985 feet.Rescuers retrieved his body Thursday and treated his climbing partner, Aidan Jacobson, for injuries to his ankle and other parts of his body.A fellow climber and a friend of the partner said Jacobson told him their rope got stuck, causing them to both fall 20-30 feet to the ledge below.Jacobson crashed into a bush, which broke his fall and stopped him from tumbling farther. "It pretty much saved his life," the friend, Ryan Borys, said. Jacobson told him he saw Gobright fall past him and over the ledge.The State Department confirmed Gobright's death in Mexico. "We offer our sincerest condolences to his family on their loss. We are closely monitoring local authorities' investigation and are providing all appropriate consular assistance. Out of respect to the family during this difficult time, we have no further comment," it said.Famed climber Alex Honnold, who was featured in the film "Free Solo," 1215
