**************************************************** winter preparedness week in Virginia November 30- December 6, 2014 ****************************************************

Governor Terry mcauliffe has declared the week of November 30 to December 6, 2014 as winter preparedness week in Virginia. The National Weather Service /NWS/ offices serving cooperation with the Virginia department of emergency management...will send public information statements over the NOAA weather wire service each day through Saturday at approximately 11 am. These statements will focus on different aspects of winter weather in the mid Atlantic region...and preparedness actions the public should take for the upcoming winter season.

Today's topic - heavy snow.

Last winter's biggest storm occurred on February 13 2014. This storm produced a foot or more of snow across the Shenandoah Valley and parts of northern Virginia. Other events...including March 3 2014... March 17 2014...and January 29 2014 produced 5 to 10 inches of snow across parts of Virginia.

The winter of 2009-10 reminded residents of the mid Atlantic region that it can still snow heavily multiple times during the winter season. Starting with the December 18th to 19th storm, and ending in mid February...nearly half a dozen snowstorms affected the mid Atlantic region. Seasonal snow totals of 50 to 70 inches were common from portions of northern Virginia into the Baltimore and Philadelphia areas.

December 18th-19th, 2009: heavy snow began in southwest Virginia around midday on the 18th and snows rapidly accumulated to warning levels during the late afternoon and evening hours across much of the commonwealth west of the Chesapeake Bay. All forms of travel were rendered extremely difficult for several days due to this storm...and numerous vehicle accidents were reported. Final snow totals ranged from less than 6 inches in parts of south central and interior southeast over 25 inches in parts of Alleghany...Augusta...Highland...Rockbridge... Montgomery...and Bath counties. Much of northern Virginia received 16 to 20 inches of snow. This was the biggest snowstorm to affect western Virginia since the January 6-8, 1996 storm. Several stations set December single-storm snowfall records from this storm including Roanoke and Blacksburg.

For the first time in 6 years...a major snowstorm struck the mid Atlantic region on March 1-2 2009. In some areas of central Virginia...nearly a foot of snow fell. However...a strong March sun melted much of the snow off the roads within a few hours of the end of the storm...and minimized the storm's impact on the commonwealth. Previously...the last major snowstorm to strike Virginia occurred from late on February 14th through the morning hours on February 18th, 2003. Three rounds of precipitation resulted in 20 to 36 inches of snow across far northern Virginia...decreasing to between 7 and 12 inches of snow and sleet in the central part of the mainly several inches of sleet and/or 1/4 to 1/2 inch of ice accretion in the south. A 24 hour snowfall of 16.7 inches at Ronald Reagan National Airport...was the 5th highest on record. Charlottesville recorded almost 9 inches of sleet from the storm.

Another major snowstorm affected the commonwealth on January 24th and 25th 2000. Snow began along the Virginia/North Carolina border late on the 24th and then spread north across the remainder of central and eastern Virginia. Total snowfall in excess of 6 inches generally occurred east of a line from Winchester to Charlottesville to Lynchburg to Danville. Snowfall totals up to 15 to 19 inches occurred from Fauquier County southeast to New Kent County and then southwest into Mecklenburg County. There was a sharp western edge to the snow with no snow reported mainly west of a line from Harrisonburg to Bedford to Martinsville. In much of south-central and southeastern Virginia...this was the first major snowfall since January 6th and 7th 1996.

Storm systems intensifying rapidly along the eastern Seaboard during the colder months of the year are usually responsible for producing most of the heavy snows in Virginia. These systems, called nor'easters, can also produce strong winds which may result in blizzard conditions and huge snow drifts.

Heavy snow tends to occur 100 to 150 miles to the northwest of the track of the surface low. Snow amounts well in excess of 30 inches have occurred with nor'easters in Virginia. In addition...strong winds and very cold temperatures in this same area can result in blizzard or near blizzard conditions...dangerous wind chill values...and have resulted in snow drifts up to 12 feet high.

The exact track the surface low pressure takes and how much cold air is in place ahead of the system...determines if and where heavy snow will occur. Given that cold air is in place...a surface low that travels a hundred miles or so off the coast can produce some snow in the central portion of the state...with the potential for heavy snow confined to the eastern portions of the state. If the surface low travels along the coast or slightly inland...heavy snow is most likely in the northwestern one-third of Virginia.

If the amount of cold air in place is marginal for is possible that heavy wet snow could occur in the higher elevations with just a cold rain in the lower elevations.

Heavy snow is capable of bringing down tree limbs and power lines which may result in power outages. In rare instances...heavy snow may result in the collapse of roofs of buildings and homes.

In addition...heavy snow may result in snow covered or ice covered roads. This typically leads to vehicle accidents and potentially major traffic jams. If there is enough heavy snow and/or wind... some roads may be closed and other roads may only be successfully traversed by 4 wheel drive vehicles.

The following is a summary of historic snowstorms in Virginia.

February 5-6 2010 - more than a foot of snow north of a Wallops Island to Hot Springs line...with 2 feet of snow across far northern Virginia. At least 6 inches of snow fell in most areas south of this line.

December 18-19 2009 - a foot or more of snow fell across much of Virginia...except the southeast quarter...where lesser amounts fell. Little snow fell across Hampton Roads. Snowfall records for a single December storms were set in some areas of northern Virginia.

February 14-18 2003 - 7 to 36 inches of snow across central and northern Virginia (highest far north)...significant ice southern Virginia.

January 24-25 2000- 6 to 19 inches of snow across much of central and eastern Virginia.

January 6-7 1996 - 12 to 30 inches of snow in much of western... central...and northern Virginia. A few locations in the mountains received over 3 feet of snow. Twenty four hour snowfall records were established at Roanoke and Lynchburg. In Virginia...there was one fatality directly attributed to the storm. In the mountains... strong winds on January 8th created snow drifts up to 10 feet high.

March 12-15 1993 - 20 to 30 inches of snow with some amounts over 3 feet in the mountains. In the foothills...10 to 18 inches of snow fell. In Virginia...there was one fatality directly attributed to the storm. In the mountains...strong winds up to 50 mph whipped drifts up to 12 feet high and created near blizzard conditions.

February 10-12 1983 - 10 to 20 inches of snow in a large portion of Virginia with up to 30 inches of snow in northern portions of the state. The storm established 24 hour snowfall records at Roanoke... Lynchburg...and Richmond.

March 1-2 1980 - a true blizzard in portions of southeastern Virginia with 12 to 20 inches of snow. Strong winds resulted in snow drifts up to 8 feet high.

February 18-19 1979 - this storm known as "the presidents day storm" dumped 6 to 15 inches of snow in much of Virginia with up to 20 inches of snow in northern portions of the state. Nearly 12 inches of snow occurred in Richmond with 8 inches in Norfolk.

March 5-8 1962 - 10 to 24 inches of snow in many interior portions of Virginia.

Being prepared means making good decisions based on information contained in statements and forecasts from the National Weather Service. The key is to know what to do in advance. If a winter storm like what occurred in 1993 or 1996 was predicted to hit Virginia in two days...what would you do between now and when the storm arrives to get ready? You should make sure you have enough food...water and medication for several days. You also need to be prepared for the loss of power and/or heat.
