Roadways in Fairfax County are covered in snow after flurries first started to fall around 1 p.m. and local officials are warning drivers to continue to stay home.

The Virginia Department of Transportation has trucks working on major roadways, according to its snow plow map.

As previously advised, Virginia State Police spokesperson Shelby Crouch said to avoid travel today through tomorrow to allow VDOT crews to safely and effectively work.

“During the current winter storm impacting the Commonwealth, Virginia State Police troopers have responded to 369 traffic crashes and 282 disabled vehicles since 12:01 a.m. Sunday (Jan. 16) through 4:30 p.m. Sunday (Jan. 16),” Crouch said. “The majority of those crashes have involved only damage to vehicles. There have been no reported traffic fatalities during this time period.”

State police have responded to 36 disabled vehicles & 41 traffic crashes in Fairfax today.

Dominion Energy has not seen any power outages in Fairfax County as of publication, according to its outage map, but the company said it was monitoring the storm in Virginia and had crews ready to respond to any damage or power outages.

The Washington Post’s Capital Weather Gang estimated there was about an inch of snow in the area as of 4:30 p.m.

By 5 p.m., Reston Parkway and Sunset Hills Road near Reston were blanketed with snow as it continued to fall. The National Weather Service predicts freezing rain will begin around 9 p.m., with a chance of 1 to 2 inches of new snow accumulation after that.

Here’s what the NWS says to expect through the evening:

Snow should overspread all of our region by 21Z with light to moderate snow likely for most of the region through the early parts of the evening. A warm layer aloft should start moving into our region at 850 mb this evening leading to transition from snow to a wintry mix of snow, sleet and freezing rain for areas east of I-81. Areas along the I-95 corridor should start transitioning first between 5 and 8 pm this evening, with the warm layer continuing to push westward with the transition shifting over the shenadoah Valley by the 6 to 9pm period. The I-95 corridor should become all rain by the 7 to 9pm period as temperatures rise above freezing with the all rain layer likely reaching as far west as areas just east of I-81. Our high temperatures for Monday may very well occur around midnight or early Monday morning due to the warming on-shore flow. I believe the Allegheny front should remain mainly snow with periods of sleet and freezing rain mixing in at times this evening and into early Monday morning. Precipitation is expected to start tapering off early Monday morning between midnight and 2am with snow likely to continue along the Allegheny front into Monday.

A strong low level easterly jet is expected to form late this evening and into Monday evening. Winds of 35 to 45 mph`s will be possible over our higher elevations with 25 to 35 knots possible else where. Continued light to moderate snow showers along the Allegheny front will combine with the strong winds to produce some near Blizzard like conditions along and west of the Allegheny Mtns. We have highlighted this threat in our WSW product. The overnight
gusty winds should taper off by daybreak but gusts of 20 to 25 mph should continue into Monday morning.

Expected snowfall for D.C. area on Jan. 16-17 (via National Weather Service/Twitter)

(Updated at 11:55 a.m.) A Winter Weather Advisory has been issued for Fairfax County, as the D.C. area prepares for its second snowstorm of the year.

In effect from 1 p.m. today (Sunday) to 1 a.m. tomorrow (Monday), the alert warns of mixed precipitation that will create slippery, hazardous road conditions.

The National Weather Service anticipates snow accumulations of 1 to 3 inches and one-tenth of an inch of ice, along with wind gusts that could reach speeds of 45 miles per hour. With temperatures expected to drop below freezing tonight, travel could be affected through tomorrow morning.

The Virginia Department of Transportation began pretreating roads with brine on Friday (Jan. 14) and mobilized snow plow crews this morning, deploying more than 3,800 pieces of equipment throughout Northern Virginia, according to a 10 a.m. snow update.

“Plan your trips now to avoid all nonessential travel on Sunday into Monday, especially during the height of the storm, to avoid deteriorating conditions and to allow crews room to work,” VDOT said.

Fairfax County Public Schools has canceled all activities on school grounds after 1 p.m.

Fairfax Connector plans to continue operating regular Sunday service, but detours could be implemented along some routes starting at 3 p.m.

After the Jan. 3 snowstorm took out power for about 500,000 households across the state, including tens of thousands of people in Fairfax County, Dominion Energy says crews and contractors from as far away as Louisiana and Oklahoma will be on hand to assist with its emergency response.

“Our crews are ready to once again rise to any challenge this storm will bring,” Charlene Whitfield, Dominion’s senior vice president of power delivery, said in a news release. “Customers should prepare, as well, so they can remain safe until our work is done.”

Dominion advises avoiding downed power lines and reporting outages through its website or to 1-866-DOM-HELP (1-866-366-4357) to ensure the fastest possible response.

Another winter storm is brewing, potentially bringing 3 to 4 inches of snow to Fairfax County on Sunday and Monday (Jan. 16-17).

The National Weather Service has issued a Winter Storm Watch for the D.C. area, including Fairfax County. The alert will take effect at 1 p.m. on Sunday and last through 7 a.m. Monday, when the snow is  expected to turn into a wintry mix with sleet and freezing rain.

The NWS projects total snow accumulations of 1 to 3 inches as the most likely scenario, though up to 5 inches could be possible. The forecast also includes up to an one-tenth of an inch of ice accumulation and wind gusts that could reach 45 miles per hour.

“Snow may fall at 1 to 3 inches per hour late Sunday afternoon and early Sunday evening, resulting in
nearly impassable roads,” the alert says, warning that slippery and hazardous road conditions could affect Monday’s commute.

Preparations for the coming storm are underway, with the Virginia Department of Transportation treating roads throughout Northern Virginia today.

“Since dry conditions are expected, we are able to brine throughout Fairfax, Loudoun and Prince William counties,” VDOT spokesperson Kathleen Leonard told FFXnow. “Drivers will start to see those white brine lines, which really just gives us a little bit of time at the beginning of the storm, preventing ice from bonding to the pavement.”

Leonard says snow trucks will be staged tomorrow (Saturday) so that plowing operations can begin once the area gets about two inches of snow.

Gov. Ralph Northam, who will be officially succeeded by Glenn Youngkin tomorrow, declared a state of emergency today in anticipation of the storm.

“Declaring a state of emergency now allows our emergency responders to prepare, and to move supplies and equipment where they expect to need them the most,” Northam said. “This also gives Governor-elect Youngkin the ability to respond to any storm needs swiftly. I urge Virginians to take this storm seriously and make preparations now.”

VDOT and the Virginia State Police are both advising people to avoid traveling during the storm, though the police agency says all available troopers will be on patrol to respond to crashes and disabled drivers.

While schools will be closed on Monday for Martin Luther King Jr. Day, Fairfax County Public Schools says students and staff should bring their computers home today in case a snow day is needed next week.

Any snow days will include virtual learning, because the school system already used its five designated “traditional” snow days after a snowstorm slammed the D.C. region last week, disrupting transportation and power networks.

Dropping up to 3 inches of snow per hour, Winter Storm Frida affected 58,000 miles of roadway across Virginia and took out electricity for approximately 500,000 households, according to VDOT, which is part of a multi-agency review of the state’s response after hundreds of motorists were stranded for hours on I-95.

In Fairfax County, snowfall totals on Jan. 3 ranged from 4.5 inches in Herndon to 11.8 inches in Franconia.

Fairfax County Public Schools announced just after 5 p.m. that classes will be canceled again. Students were scheduled to return from winter break on Monday, but it has now been extended four extra days.

“Across Fairfax County, we continue to receive reports of roadways, sidewalks and pathways that remain unsafe for our students, and so we are closing schools out of an abundance of caution, and the concern for safety of our students,” FCPS said on social media.

Unlike with previous cancellations, the school system says its COVID-19 testing sites will all be open for students and staff experiencing symptoms. Plans to resume meal kit distributions are also move forward.
