Giant panda's heartwarming snow day

Washington, D.C., residents are expecting a strong snowstorm to hit the city Friday afternoon. Washington Mayor Muriel Bowser has asked residents to prepare to be indoors for 36 hours with the possibility of no power or no water during that time.

Washington residents emptied grocery stores around the nation’s capital for supplies.

“It has life-and-death implications, and (people) should treat it that way,” Bowser told residents Friday. “People should hunker down, shelter in place and stay off the roads.”
