(Updated at 5 p.m.) The northern section of the George Washington Memorial Parkway will close tonight (Friday) in anticipation of some snowfall, the National Park Service says.

The closure will start at 7 p.m. and extend from the Capital Beltway (I-495) in McLean to Spout Run in Arlington.

“This closure is necessary to ensure the proper treatment of the roadway and to restore the parkway to safe travel conditions,” the park service said in its announcement of the closure this morning. “Crews will work diligently to treat the road for safe passage of drivers. Drivers should anticipate delays in reopening the northern section of the parkway as crews are required to use smaller equipment than usual to accommodate the lane widths and configurations.”

Drivers are advised to plan to use an alternate route.

As rehabilitation work continues on the northern GW Parkway, the NPS instituted a policy this winter of closing the road whenever 2 or more inches of snow are forecast.

The National Weather Service issued a Winter Weather Advisory this morning for the D.C. area, including Fairfax County that will be in effect from 11 p.m. to 7 a.m. tomorrow (Saturday). Two to four inches of snow are expected, though some areas could potentially see as many as six inches, according to the advisory.

The impending storm has already prompted the Town of Vienna to cancel classes that were scheduled for tomorrow at the Vienna Community Center and Bowman House.

“The Community Center is expected to open at 10:30 a.m. for rentals and public use,” the town said in a tweet.

Fairfax County Public Schools has nixed all activities set to take place on school grounds before noon tomorrow, including extracurricular activities, athletic team practices and non-FCPS community and recreational programs.

Here’s the full advisory from the NWS:

…WINTER WEATHER ADVISORY NOW IN EFFECT FROM 11 PM THIS EVENING TO 7 AM EST SATURDAY…

* WHAT…Snow expected. Total snow accumulations of 2 to 4 inches, with isolated totals up to 6 inches possible under heavier snow bands.

* WHERE…Portions of central Maryland, The District of Columbia, and northern Virginia.

* WHEN…From 11 PM this evening to 7 AM EST Saturday.

* IMPACTS…Plan on slippery road conditions.

* ADDITIONAL DETAILS…Snowfall rates of 1 to 2 inches per hour are possible for a few hours under the heaviest snow bands. Visibility may be reduced to less than one half mile at times.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

Slow down and use caution while traveling.

When venturing outside, watch your first few steps taken on steps, sidewalks, and driveways, which could be icy and slippery, increasing your risk of a fall and injury.

Updated at 6 p.m.The GW Parkway has reopened after closing for the snow, the National Park Service announced, though both north and southbound traffic is limited to a single lane in the construction area.

Earlier: Like the snow that triggered them, facility closures and service delays are piling up in Fairfax County.

After Fairfax County Public Schools determined last night that it will have a snow day today (Friday), the Fairfax County government announced shortly before 7 a.m. that it will instead close and grant employees administrative leave — a reversal of an earlier plan to operate as usual.

The closure includes the Fairfax County Government Center, which means that early voting for the 2024 presidential primaries won’t start today as scheduled. Instead, early voting will begin tomorrow (Saturday) from 9 a.m. to 5 p.m. at the Fairfax County, Mount Vernon and North County government centers.

The closure also applies to all Fairfax County Park Authority facilities and the county’s circuit, general district and juvenile and domestic relations courts. Neighborhood and Community Services has also preemptively postponed the “Stuff the Bus” food collection event that was scheduled for tomorrow (Saturday) outside the West Falls Church Giant (7235 Arlington Blvd).

For the second time this week, the northern section of the George Washington Memorial Parkway from I-495 in McLean to Spout Run in Arlington has been temporarily closed to traffic due to the weather.

“This closure is necessary to ensure the proper treatment of the roadway and to restore the parkway to safe travel conditions,” the National Park Service said. “Crews will work diligently to treat the road for safe passage of drivers. Drivers should anticipate delays in reopening the northern section of the parkway as crews are required to use smaller equipment than usual to accommodate the lane widths and configurations.”

The NPS has said that it will shut down the roadway, which is under construction, if two or more inches of snow are forecast.

Other travel impacts include reduced Metrobus service, including some suspended routes and detours. Fairfax Connector is operating regular service, but some routes are making detours, particularly in the Herndon area.

A light snow is expected to continue falling into this afternoon, potentially adding another one to two inches, according to the Capital Weather Gang, which reported that more than three inches had already been recorded at Dulles International Airport before 9 a.m.

That snowfall comes on top of the two to five inches that fell on Monday and Tuesday, most of which hadn’t yet melted. That storm was the first time that the D.C. area had gotten over an inch of snow since 2022.

The National Weather Service, which has a Winter Weather Advisory in effect for the D.C. area through 7 p.m., warns that visibility will stay reduced along the I-66 and Route 50 corridors.

The D.C. area is expected to be hit with another round of snow tomorrow (Friday), prompting Fairfax County Public Schools to call for its second snow day this week.

All schools and central offices will be closed tomorrow, FCPS announced at 5:25 p.m. today. The closure includes extracurricular activities, field trips and other events on school grounds.

Classes were also canceled on Tuesday (Jan. 16) and started two hours late Wednesday after the region got more than an inch of snow for the first time in nearly two years.

The National Weather Service has issued a Winter Weather Advisory for Fairfax County that will take effect from 4 a.m. to 7 p.m. tomorrow. One to three inches of accumulated snow are possible, adding onto the three to five inches that fell earlier this week and have yet to fully melt.

The Virginia Department of Transportation says its Northern Virginia District crews started spot-treating roads with brine today and will continue once snow begins to fall tomorrow morning.

Here’s the full winter weather alert from the NWS:

…WINTER WEATHER ADVISORY IN EFFECT FROM 4 AM TO 7 PM EST FRIDAY…

* WHAT…Snow expected. Total snow accumulations of 1 to 3 inches north of US-50/I-66 with amounts around 1 inch to the south.

* WHERE…Portions of central and southern Maryland, The District of Columbia and northern and northwest Virginia.

* WHEN…From 4 AM to 7 PM EST Friday.

* IMPACTS…Plan on slippery road conditions. The hazardous conditions will impact the morning commute.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

Slow down and use caution while traveling.

When venturing outside, watch your first few steps taken on steps, sidewalks, and driveways, which could be icy and slippery, increasing your risk of a fall and injury.

Fairfax County Public Schools is using up its first snow day of the year, canceling all classes and other activities on school grounds tomorrow (Tuesday) as flurries continue to blanket the D.C. area.

Affected activities include extracurricular programs, sports practices, field trips, outside recreation classes, adult education classes and the School Age Child Care (SACC) centers.

FCPS has 11 snow days built into its calendar, and unlike in the past couple of years, students don’t need to fear a shift to virtual classes after the first five days.

A Winter Weather Advisory is currently in effect for the county through 7 a.m. tomorrow. The National Weather Service projects that this storm could result in two to three inches of snow accumulation, along with possible freezing rain and drizzle, according to the Fairfax County Department of Emergency Management.

“Snow intensity will increase this evening before tapering off overnight,” the NWS said, warning that the “hazardous” road conditions could still affect tomorrow’s morning commute.

In anticipation of the roadways becoming a challenge, Fairfax Connector will reduce service starting at 8 p.m. today (Monday). The bus system will continue running several routes on a holiday weekday service, but some will end at or around 8 p.m.

Tomorrow, the Connector will implement a Saturday service schedule. A list of the specific routes that will be provided can be found on the Fairfax County Department of Transportation’s website, and minute-by-minute status updates will be available through BusTracker.

The George Washington Memorial Parkway has been temporarily closed in the McLean area. Due to ongoing construction, the National Park Service previously announced that the section from I-495 to Spout Run in Arlington would close if two or more inches of snow are forecast.

Here’s the full message from the NPS:

The George Washington Memorial Parkway, from 495 to Spout Run, is closed due to the forecasted severe winter weather in the area. This closure is necessary to ensure the proper treatment of the roadway and to restore the parkway to safe travel conditions. Crews will work diligently to treat the road for safe passage of drivers. Drivers should anticipate delays in reopening the northern section of the parkway as crews are required to use smaller equipment than usual to accommodate the lane widths and configurations. Please plan to use alternate routes.

A follow-up alert will be distributed once the parkway has reopened. Thank you in advance for your patience.

A High Wind Warning has been issued for the D.C. area starting at 3 p.m. on Jan. 9 (via NWS/Twitter)

Updated at 3:35 p.m. — A Flood Warning has been issued until 11:30 p.m., for Northern Virginia, including Fairfax County, where “flooding caused by excessive rainfall is expected.”

Earlier: Fairfax County Public Schools has called off all remaining activities on school grounds today (Tuesday) in anticipation of a strong rainstorm expected to last through this evening.

“Given the strength of the storm predicted to hit our area later this afternoon/evening, all activities scheduled in Fairfax County Public Schools or on school grounds for this afternoon and evening are canceled,” the school system said.

The cancellations apply to all extracurricular activities, team practices, after-school programs, field trips, adult classes and outside recreational programs by groups not affiliated with FCPS.

The announcement came as the National Weather Service warns that conditions will “deteriorate as a strong frontal system” passes through the D.C. region between 5 and 10 p.m. The rain that has been falling all day is projected to increase in intensity through the afternoon, becoming heaviest starting at 6 p.m.

“This will result high winds capable of downing trees and powerlines, tidal flooding, and the potential for flooding of small streams and creeks,” the NWS said in a special weather statement. “This will create hazardous travel conditions late this afternoon through late evening across the region.”

As previously forecast, a Flood Watch took effect at 1 p.m. and is set to remain in place until 7 a.m. tomorrow (Wednesday).

The NWS has also issued a High Wind Warning for 3 p.m. to 1 a.m. tomorrow and a Coastal Flood Warning for Fairfax County that will be in effect from 10 p.m. to 10 a.m.

Southeast winds could reach 25 to 40 mph with gusts of up to 60 mph, while low-lying areas may get 1 to 2 feet of water above ground level as a result of tidal flooding, according to the NWS.

“Tides up to 3 feet above normal,” the agency said in the flood warning. “Moderate tidal flooding is possible along the Prince Georges and Fairfax counties coastlines during tonight’s high tide cycle.”

Because of the strong winds, power outages are expected, and travel will be difficult, the Fairfax County Department of Emergency Management says, sharing tips for how to prepare and who to call in the event of an outage:

Take Action

  • Secure outdoor objects, including trash cans, holiday decorations and other items.
  • Be careful when you’re outside, especially around areas with lots of trees.
  • Charge phones in case of a power outage.
  • If you lose power, report your outage, use flashlights or battery-powered lanterns.

In case you didn’t get your fill of rain on Saturday (Jan. 6), another downpour could be in store for Fairfax County this week.

The National Weather Service has issued a Flood Watch and a Wind Advisory for the mid-Atlantic region, including Fairfax County and the rest of northern Virginia, ahead of a storm that’s expected to travel up the East Coast tomorrow (Tuesday).

Issued this morning, the Flood Watch is currently set to take effect at 1 p.m. tomorrow and remain in place until 7 a.m. Wednesday (Jan. 10). The alert warns that flooding caused by “excessive rainfall” of two to three inches is possible.

The forecast indicates that the heaviest period of rain will come in the afternoon and evening.

“Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations,” the NWS said. “Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded.”

The Wind Advisory will be in place from 3 p.m. tomorrow to 1 a.m. Wednesday. Southeast winds may reach 20 to 30 mph with gusts up to 50 mph, according to the NWS.

“Gusty winds could blow around unsecured objects. Tree limbs could be blown down and a few power outages may result,” the alert says.

According to the Capital Weather Gang, the incoming storm will be similar to the one that hit on Saturday, fueled by warm air from the south that will turn most of the precipitation into rain.

Forecasts last week suggested Fairfax County could get up to an inch of snow and sleet accumulation from Saturday’s winter storm. NWS data for the Dulles Airport area indicates that the 0.97 inches of precipitation recorded that day was mostly rain, though there were “trace” amounts of snow.

The season’s first winter storm is making its way toward the D.C. region, though the chances for serious snow in Fairfax County are iffy.

Instead, the county is expected to get a slushy mix of rain, snow and sleet, starting tomorrow (Saturday) morning. The precipitation could add up to an inch of snow and sleet accumulations, along with “a light glaze” of ice, according to a Winter Weather Advisory issued today by the National Weather Service.

The advisory, which also includes central and southeast Prince William County, is scheduled to take effect at 7 a.m. tomorrow and stay in place until 2 p.m. After that, the wintry mix is anticipated to turn into rain.

“Slow down and use caution while traveling,” the NWS said. “When venturing outside, watch your first few steps taken on steps, sidewalks, and driveways, which could be icy and slippery, increasing your risk of a fall and injury.”

Fairfax County notes that some of its facilities may close and programs might get canceled, depending on the severity of the weather.

Virginia Department of Transportation crews began treating roadways with salt brine this morning, a process that will be complete by this afternoon’s rush hour, according to a snow update.

The full Winter Weather Advisory is below:

…WINTER WEATHER ADVISORY IN EFFECT FROM 7 AM TO 2 PM EST SATURDAY…

* WHAT…Mixed precipitation expected. Total snow and sleet accumulations of a coating to an inch, and ice accumulations of a light glaze.

* WHERE…Fairfax County, and Central and Southeast Prince William County.

* WHEN…From 7 AM to 2 PM EST Saturday.

* IMPACTS…Plan on slippery road conditions and slippery untreated paved surfaces, mainly from light ice glaze due to freezing rain.

* ADDITIONAL DETAILS…Precipitation is expected to begin as snow and sleet between 7 and 9 AM. Precipitation will change to freezing rain around 11 AM, then rain after 2 PM. Precipitation is expected to end during the early evening.

There will be a chill in the air tomorrow (Tuesday) morning — and it’s not just because Halloween will only be a week away.

A Frost Advisory is set to take effect for portions of Maryland and Virginia, including Fairfax County, from 2-10 a.m., the National Weather Service announced today.

“Temperatures as low as 33 will result in frost formation,” the NWS said, warning that the frost could be fatal to sensitive outdoor vegetation.

The agency advises covering plants or taking other steps to protect them from the cold.

For Fairfax County, the NWS is currently forecasting “patchy frost” for tomorrow, likely between 4 and 9 a.m. Temperatures could range from a low of 35 degrees to a high of 67.

However, a warming trend is anticipated later in the week, according to the NWS and the Washington Post’s Capital Weather Gang. The forecast shows temperatures climbing to a high of 78 degrees on Friday (Oct. 27).

Looking into the slightly more distant future, the NWS projects that the D.C. area will get another mild winter, though emerging El Niño weather patterns could bring the snowstorm that was absent last year, according to the Capital Weather Gang.

Tropical Storm Ophelia is expected to bring rain and wind to Northern Virginia this weekend (via National Weather Service)

Updated at 4:05 p.m. — A Coastal Flood Advisory issued for parts of Northern Virginia, including Fairfax County, will now take effect at midnight, earlier than initially anticipated, the National Weather Service says.

Earlier: It’s going to be a cold and rainy weekend in Fairfax County, thanks to Tropical Storm Ophelia.

Tracking to make landfall in North Carolina today (Friday), the storm is expected to reach Northern Virginia tonight with “heavy rain, high winds, and cool temperatures” continuing into Sunday (Sept. 24) morning, according to the Fairfax County Department of Emergency Management.

“Locally, [the National Weather Service] expects 2-4 inches of rain throughout the weekend,” the county said in a post on its emergency information blog. “Since the precipitation will be spread across the weekend, flooding is not a major concern but could cause some localized flooding issues. Wind speeds will gradually increase, peaking around 40 mph on Saturday.”

The storm has already affected some major events, prompting cancellations of the popular Reston Multicultural Festival, the inaugural Fairfax Fiesta in Tysons and a kick-off for National Public Lands Day in Annandale. Other events, like Fairfax City’s Fiesta Fairfax, have been relocated indoors.

The NWS has issued a Coastal Flood Advisory and a Wind Advisory for much of the D.C. area, including Fairfax County.

The flood advisory will be in effect from noon tomorrow (Saturday) to 5 a.m. Sunday:

* WHAT…Up to one half foot of inundation above ground level expected in low lying areas due to tidal flooding.

* WHERE…Fairfax, Stafford and Central and Southeast Prince William/Manassas/Manassas Park Counties.

* WHEN…From noon Saturday to 5 AM EDT Sunday, especially around the time of high tide.

* IMPACTS…Flooding of lots, parks, and roads with only isolated road closures expected.

* ADDITIONAL DETAILS…Tides one and a half to two feet above normal. The worst flooding will occur with the Saturday afternoon and Saturday night high tides.

The Wind Advisory will take effect at 8 a.m. tomorrow and last until 8 p.m., warning that northeast winds could reach 20 to 30 mph with up to 45-mph gusts. The NWS notes that the “gusty winds” could blow around objects and result in power outages. Read More
