An historic January storm dumped more deep snow along the U.S. Gulf Coast on Wednesday after bringing Houston and New Orleans to a near standstill over the past two days and burying parts of Florida’s Panhandle with accumulations more typical of Chicago. Another 4 inches (10 cm) of snow, combined with sleet and freezing rain, was expected to pile up in some spots in northern Florida, southern Georgia and southeast South Carolina as the storm crawled through the region, the National Weather Service said on Wednesday.
