• Dense Fog in Virginia, March 31, 20133 deaths · 25 injured · $500,000 · 1 eventDense fog near Fancy Gap helped to create the conditions for a massive pileup on southbound Interstate 77 in Carroll County. A warm front had lifted northward across the region during the early morning hours accompanied by showers.
• Dense Fog in Virginia, August 29, 20101 death · 1 injured · 1 eventDense fog, with visibilities down to 1/4 mile or less may have been a contributing factor in a 2-vehicle accident on Interstate 77 in Wythe County. The crash occurred about 5:20 a.m. when a woman drove the wrong way on the interstate and collided with a tractor-trailer.
• Dense Fog in Virginia, September 27, 2010$500,000 · 1 eventDense fog developed along the Fancy Gap corridor of Interstate 77. Between mile markers six and seven, a vehicle accident occurred between a car and a tractor trailer at 14:00 EST.
• Dense Fog in Virginia, May 21, 2001$300,000 · 1 eventForty to fifty vehicles were involved in a chain reaction accident in dense fog on Interstate Route 77 at Fancy Gap during the early afternoon of the 21st.
• Dense Fog in Virginia, October 22 to 23, 201923 eventsAn onshore flow led to increasing amounts of moisture underneath a strong temperature inversion, and this led to the development of dense fog. Visibility was reported to be around one-quarter mile.
• Dense Fog in Virginia, March 24 to 25, 202123 eventsLight winds and plentiful low level moisture allowed areas of dense fog to form late on the 24th. The fog dissipated just after dawn on the 25th.
• Dense Fog in Virginia, January 12, 200622 eventsAreas of dense fog occurred early in the morning of January 12 across the region.
• Dense Fog in Virginia, February 27, 200721 eventsAreas of dense fog formed during the early morning hours across the foothills of the Blue Ridge Mountains east towards Interstate 95. Visibilities across the area were reduced to less than a quarter mile.
• Dense Fog in Virginia, January 12 to 14, 201321 eventsHigh pressure was centered off the Atlantic coast. Southerly flow has transported mild temperatures and moisture northward into the Mid Atlantic Region. Calm winds and low level moisture led to dense fog overnight. This was the second consecutive day of dense fog in the region.
• Dense Fog in Virginia, July 25 to 26, 201821 eventsLow-level moisture was trapped underneath the nocturnal inversion. Breaks in the clouds caused radiational cooling, which led to areas of dense fog.
• Dense Fog in Virginia, October 8, 201821 eventsHigh levels of moisture combined with clear skies to create areas of fog, some of which became locally dense.
• Dense Fog in Virginia, June 23, 202021 eventsLight winds and ample moisture at low levels thanks to storms the previous day resulted in the formation of dense fog across much of the central Virginia Piedmont, Shenandoah Valley and portions of northern Virginia.
• Dense Fog in Virginia, October 19, 200620 eventsDense fog occurred early in the morning of the 19th. Visibilities were reduced below one-quarter mile in some areas.
• Dense Fog in Virginia, December 24 to 25, 201219 eventsHigh pressure was located over the Atlantic Ocean and an upper trough of low pressure moved into the Ohio Valley. Flow between the exiting high and approaching low pressure caused onshore flow to develop that led to dense fog across the Mid Atlantic.
• Dense Fog in Virginia, September 29, 201819 eventsA combination of clear skies, abundant low level moisture, and light winds led to the formation of fog, some of which became dense with visibility less than a quarter of a mile.
• Dense Fog in Virginia, January 14 to 15, 202019 eventsMoist air at low levels was trapped beneath a subsidence inversion and winds went calm as high pressure moved overhead, leading to the formation of fog across much of Northern and Central Virginia. Visibilities were around a quarter of a mile.
• Dense Fog in Virginia, November 9, 202019 eventsLow level moisture and light winds allowed widespread dense fog to develop before dawn. The fog dissipated after sunrise.
• Dense Fog in Virginia, September 9, 200618 eventsDense fog affected the Central Shenandoah Valley and Northern Piedmont with visibilities reduced to between one-quarter and one-half mile in many areas. Visibilities were reported below one-quarter mile in localized areas.
• Dense Fog in Virginia, March 24 to 25, 200718 eventsSaturated ground and light winds allowed dense fog to develop. Automated surface observations reported visibilities of a quarter mile or less during the late evening hours of March 24th through mid morning on March 25th.
• Dense Fog in Virginia, March 22, 201218 eventsHigh pressure off the coast provided an onshore flow across the area. The onshore flow off the Atlantic Ocean resulted in areas of dense fog.
• Dense Fog in Virginia, January 18, 201918 eventsWarm, moist air aloft overrunning colder surface air combined with lingering low level moisture to produce low clouds and widespread dense fog across portions of the region.
• Dense Fog in Virginia, January 26 to 27, 202118 eventsLight winds and residual moisture allowed fog to develop in the evening of January 26th. The fog dissipated early on January 27th.
• Dense Fog in Virginia, May 8 to 9, 201317 eventsHeavy rain occurred during the day as low pressure moved north of the Mid Atlantic. Low level moisture was in place and breaks in the cloud cover led to fog development overnight.
• Dense Fog in Virginia, December 17, 201917 eventsMoisture underneath a subsidence inversion resulted in areas of dense fog. Visibility was around one-quarter mile.
• Dense Fog in Virginia, May 17, 202117 eventsLight winds and plenty of low level moisture allowed areas of dense fog to form before dawn. The fog dissipated shortly after sunrise.
