Statement as of 12:34 PM EST on February 05, 2010

.... Record snowfall forecast in the Baltimore-Washington DC region...

.... Extremely dangerous winter weather conditions developing tonight...

Gusty northeast winds 20 to 30 mph with visibilities frequently
falling below one-quarter mile due to heavy snow will develop
tonight to produce near-blizzard and extremely hazardous winter weather
conditions tonight through Saturday morning. Travel is highly
discouraged tonight and will be very dangerous.

Looking back at the biggest storm of record for Washington DC... the
January 1922 Knickerbocker storm... 28.0 inches of snow was
produced from 3.02 inches of liquid water. Current forecasts for
this event have total liquid falling from this storm approaching 3
inches... which accordingly would create a snowfall that will rival
the Knickerbocker storm total. Generally across the region... 20 to
30 inches of snow will fall by Saturday evening...
