When is that snowplow going to arrive?

Snow is planned for Sunday. While we probably won’t have to worry about getting snowed in, isn’t it nice to know that you can now check the status of snowplows in real-time? You might want to bookmark the VDOT Snowplowing Map for Northern Virginia.

From the VDOT news release:

VDOT has organized northern Virginia streets into 600 “snow maps” which are assigned to plow drivers. These are the maps users will view and be able to find out whether crews are plowing, have plowed or have not started a particular snow map.  Street-by-street progress is not shown.

Users can enter an address in northern Virginia to see a color-coded snow map that indicates the plowing status in that area:

• Green indicates a neighborhood has been plowed,
• Yellow means plows are in progress in the neighborhood,
• Blue indicates plows have not yet started the neighborhood; and,
• Gray means the area is not maintained by VDOT.  Cities, towns and some developments maintain their own roads.

“This is a test run so we will welcome feedback from the public,” said northern Virginia VDOT Assistant District Administrator Branco Vlacich.  “We will make adjustments as needed to make it as user-friendly and helpful as possible.”

Residents can view a video of how to use the webpage at http://youtu.be/HMRaItZLgyo.

Quick Tips for Users

• Be sure to enter your complete address, e.g. 100 Maple Street, Anytown, Virginia.
• The website tracks VDOT-maintained neighborhoods only.
• The website is active only when two or more inches of snow have fallen.

How VDOT clears subdivisions in northern Virginia

Trucks are pre-positioned in subdivisions whenever the forecast calls for two or more inches of snow.  Each subdivision has at least one dedicated truck and plowing begins when two inches have accumulated. Main thoroughfares are repeatedly plowed during a storm. Once the storm has stopped and those roads are clear, crews work to make residential streets and cul-de-sacs “passable.”

A neighborhood street is considered passable when a path is drivable (with caution) for an average passenger vehicle. The road will not be cleared curb-to-curb or to bare pavement, and may remain snow-packed, uneven and rutted (especially following any refreeze). Chemicals are not typically used in subdivisions, but crews sand hills, curves and intersections as needed to provide traction. For most storms, one snowplow pass, about eight to ten feet wide, is made.

Once drivers complete a minimum of one pass on the roads in a map, they report back that the route is complete.

VDOT judges subdivisions complete through processed snow maps, resident call volume, AVL and feedback from VDOT monitors.

February 10th Snowstorm adds 7 inches of new snow to Oak Hill — 100 year record set

From the National Weather Service, some snowfall mostly unofficial readings for Fairfax County:

7 inches is about right. Add this to the 24-27 inches received on the February 6-7 storm and close to a yard of snow is now on the ground.

As if this were not enough, the Washington region set a hundred year for snowfall this season today according to The Washington Post.

Reagan National Airport (DCA) reported 1″ of snow between 1 and 2 p.m., upping its storm total to 9.8″. It has received 54.9″ this year, exceeding the 54.4″ of 1898-1899.

Snowpocalypse Update — 32.4 inches of snow at Dulles

Some local snowfall measurements, some unofficial courtesy of the National Weather Service. Note the official 32.4 measured at Washington Dulles below. Herndon readings suggest 24-26 inches of snow, or about five inches more than we received in the December 19-20 storm.

Snowpocalypse Part Two buries Oak Hill

With all the snow and drifting snow it is hard to get an accurate measurement of snowfall. Here are some snowfall measurements at suggest that Oak Hill has had about 15 inches of snow as of early this morning. Most likely we are closer to twenty inches at this point. This storm will probably break all records. The storm is supposed to last until around ten p.m. tonight.
