The D.C. Emergency Management Agency reports (via the AlertDC text service) that the city will pre-treat roads in advance of a storm expected early on the morning of New Year’s Eve — a storm that will close out the last day of 2009 with an awful wintery mix. District Department of Transportation and Department of Public Works will suspend leaf-collection services on Thursday so that the crews can mount plows and salt spreaders on the trucks. Though officials are not predicting a snowpocalypse-level event, they do expect roads to re-freeze late on New Year’s Eve and for hazardous conditions to carry over on New Year’s Day. Be mindful, plan to stay in (or out), take advantage of the bevy of public transit options provided by Metro, and remember: The New Year can only improve from wintery-mix conditions.
