Eastern U.S. faces flooding and snowstorms as cold temperatures sweep Plains

The Eastern U.S. is preparing for severe weather, with flood warnings issued in Kentucky, Tennessee, West Virginia, and Arkansas. Heavy rain could lead to flash flooding, prompting Kentucky's governor to declare a state of emergency. In the Northeast, snowstorms are expected, with accumulations of six to 13 inches and wind gusts up to 45 mph. Travel conditions may become nearly impossible due to snow, sleet, and ice. A polar vortex is bringing extremely cold temperatures to the northern Rockies and Plains, with Denver expecting lows of 14 degrees Fahrenheit. Meanwhile, Southern California faces risks of mudslides following recent storms, despite a return to dry weather.
