Event: Special Weather Statement
Sender Name: NWS Baltimore MD/Washington DC
Issued: 2017-12-15T00:09:53-05:00
Expires: 2017-12-15T03:00:00-05:00
Description: There is a potential for hazardous commuting conditions for the
Friday afternoon commute. Light snow (with potential large impact
due to sub-freezing road temperatures) is POSSIBLE between 1pm
and 5pm Friday afternoon. There is a 50 percent chance of snow for
Washington and Baltimore. If there is accumulation, it is
expected to be less than an inch.

If this threat of light snow on frigid roads does materialize
Friday afternoon, the Friday afternoon rush-hour could quickly
turn icy on untreated road surfaces. This could lead to hazardous
traveling conditions, multiple accidents, and extensive delays.

If you plan on commuting Friday afternoon, be aware of the
POSSIBILITY of travel disruptions and icy roads. Plan ahead by
allowing for extra travel time, and consider using public
transportation and telework options.

Stay tuned for updates on this potential winter weather episode.
