An ice storm that hit large parts of Texas and neighboring states on Monday cut power to thousands of customers, led to hundreds of traffic accidents, and caused almost 1,500 flight cancellations. The National Weather Service (NWS) issued a winter storm warning for northern Texas, southern Oklahoma, and western Arkansas. The storm carried strong winds and dropped freezing rain that turned roads into sheets of ice. At the Dallas/Fort Worth international airport, one of the busiest in the United States, almost 1,100 flights were canceled as of noon Monday. At another Dallas airport, more than 100 flights were canceled. In Tennessee, at least 22 people have died in the past few days due to icy conditions, state authorities said. In Kentucky, snow and ice has killed eleven people in the last week, officials said. Texas schools were closed Monday around Dallas and Fort Worth, while traffic on highways was light. In Arkansas, Governor Asa Hutchinson allowed state employees in affected areas to report to work two hours later than usual. In Louisiana, schools and state offices were closed in 23 counties, the office of Governor Bobby Jindal said. Along the U.S. east coast and in northern states, millions of residents were set to receive another front of arctic air Monday following weekend snowstorms, the NWS said.
