WASHINGTON (DC News Now) -- As D.C. residents brave another night of feels-like temperatures in the single digits, concerns linger for the safety of pedestrians, drivers and the city's most vulnerable. Though most main thoroughfares have been largely cleared of snow, some side streets remain messy from packed snow and ice; including along Swann Street and P Street in Northwest. Some sidewalks remain icy - and dicey - across the District. Cold weather emergency remains active across DC as dangerously low temperatures continue “You’ve got to tiptoe, it’s icy," said Delonte Jenkins Thursday along Barracks Row, where ice still covers walkways. District laws say businesses and property owners must remove snow and ice within the first eight hours of sunlight after a storm, while the Department of Public Works is responsible for clearing residential streets. Overnight, the brutal cold is renewing safety concerns among the more vulnerable. “You know it’s cold out here," said Chris Robinson, who waited for a D.C. hypothermia shelter to open at 7 p.m. at the Church of Epiphany on G Street NW. Wishing the shelter would open earlier, given the already frigid temperatures during the dinner hour, Robinson said, "You get frustrated, you get angry, you get hungry.“ Dr. Omar Jaber, a pediatrician with Children’s National Primary Care, told DC News Now that hypothermia symptoms can happen quickly if people are not prepared for the elements. DC delays some trash, recycling pickup due to snow “As you start to get to temperatures in the teens, you can really get to a level of hypothermia within minutes if you’re not appropriately dressed," Jaber said. He noted that "slurred speech, lethargy and clumsiness” are among the symptoms that may warrant a visit to the emergency room. Some were taking the cold weather in stride, including Wilson Coles, who helped students with DC Public Schools safely ice skate in Navy Yard. He advised that keeping warming packets for hand warmers is helpful. “I remember, [2010 storm] 'Snowmageddon,' I remember when we used to get a lot of measurable snow every year, and it’s nice to see that we still have that capability," Wilson added. Meanwhile, four-legged "Moishe" and his owner John looked forward to heading home after picking up pet-safe ice melt. “We are kind of enjoying it, I’ve got a 15-year-old dog who would rather stay at home by the fire, but you got to get him out for nature‘s purposes,“ he said. District hypothermia shelters are managed by the DC Department of Human Services and can be located here.
