More than 10 million people are under a blizzard warning as the winter storm that caused Thanksgiving travel chaos Sunday pushes northeast from the Midwest toward the lower Great Lakes. Thousands of flights were canceled or delayed Sunday and high winds and snow are expected to continue all through Monday. Kansas Gov. Jeff Colyer issued a state of emergency and said: “We strongly recommend that you postpone travel plans, if possible; however, if you must be on the road, make sure your vehicle’s emergency kit is stocked, your gas tank is full, and your cellphone and charger are with you and someone knows your travel plans.” Some 1,273 U.S. flights were canceled Sunday evening, with delays to 5,091 more. The weather system was forecast to move into the Great Lakes region before hitting the Northeast on Monday.
