(Updated at 5:40 p.m.) A winter storm with mixed precipitation is turning out to be more snowy than expected inside the Beltway.
Arlington and the rest of metro D.C. has been added to a Winter Weather Advisory that had previously included points north and west of the city.
Around parts of Arlington and Alexandria surveyed by ARLnow.com, even treated roads and sidewalks were slushy as sleet and snow continued to fall in the early evening. A transition to rain is expected before the bulk of the precipitation moves out by midnight.
A number of crashes are being reported throughout the county, many attributed to slippery conditions. In Courthouse, police were considering closing 14th Street N. at N. Uhle Street due to cars “sliding down the hill.” On the northern end of Glebe Road, a crash was reported to be snarling traffic near Chain Bridge.
