"A man crosses a traffic-less Tremont street in downtown Boston at rush hour, Friday, Feb. 8, 2013. Deval Patrick declared a state of emergency Friday and banned travel on roads as of 4 p.m. as a blizzard that could bring nearly 3 feet of snow to the region began to intensify. As the storm gains strength, it will bring ""extremely dangerous conditions"" with bands of snow dropping up to 2 to 3 inches per hour at the height of the blizzard, Patrick said.  (AP Photo/Gene J.
