Snow falling in Ballston (photo courtesy @SDfromDC)(Updated at 7:30 p.m.) Snowflakes have started flying across Arlington, marking the beginning of what’s expected to be a significant snowstorm.

A Winter Storm Warning is now in effect, with forecasters calling for 6-10 inches of snow through noon tomorrow (Tuesday).

As of 4:20 p.m., Arlington County said it’s transitioning from a “Phase 1″ to a “Phase 2″ snow response.

“Snow crews began pre-treating primary and secondary routes earlier today with brine,” according to Arlington Dept. of Environmental Services spokeswoman Shannon Whalen McDaniel. “Most streets had residual brine from Saturday’s event, which will help with the initial snowfall this afternoon. Trucks were also hooked up with plows, chains and spreaders in preparation.”

“We’ll be on full-deployment with approximately 50 trucks until the snow stops tomorrow,” Whalen McDaniel said.

Thanks to frigid temperatures throughout the weekend, snow is sticking on pavement and grassy surfaces. Authorities are asking residents to stay home during the snowstorm, if possible, and plan for treacherous driving conditions in the days following the storm.

Long lines at the Harris Teeter store at Pentagon Row“Virginia State Police is advising all motorists to delay travel plans for tonight and/or Tuesday morning, as roads will be treacherous,” VSP said in a press release. “With the forecasted freezing temperatures, any snow and ice accumulations are expected to stick around for a few days. So it is important to prepare your home, family, and vehicle in advance.”

Long lines are being reported at various Arlington grocery stores. The Harris Teeter at Shirlington, meanwhile, is temporarily closed due to a burst pipe.

MetroAccess service is being suspended as of 6:00 p.m. Monday and will remain suspended Tuesday, according to WMATA. Metrobuses are suspended from 1:00 to 5:00 a.m., then will operate under Metro’s severe snow plan. Metrorail will operate on a Saturday schedule on Tuesday.

Arlington County Police say several accidents have been reported since the snow started falling.

vdot-logoExpect a sloppy evening commute, the Virginia Dept. of Transportation is telling Northern Virginia residents.

Forecasters say accumulating snow may start falling by mid-to-late afternoon. VDOT says its crews are out in force treating roads, but drivers should consider leaving work early.

From a press release:

The Virginia Department of Transportation is asking northern Virginia drivers to prepare for today’s afternoon commute, which is expected to be much more difficult than this morning as rain and wintry mix increases to snow throughout the day.

Drivers are asked to commute and travel in the early afternoon if possible, prior to 4 p.m., to get ahead of increasing precipitation and dropping pavement temperatures expected this evening.

Between the morning and afternoon rush hours today, crews will apply a light application of salt, or mix of salt and liquid magnesium chloride, to problem spots such as bridges, ramps, hills and overpasses on main roads and in neighborhoods. Crews will continue to treat roads through the evening rush and overnight tonight.

Bridge and pavement temperatures are forecasted to be at or below freezing from 6 p.m. today through mid-day Tuesday. Drivers are asked to use caution, particularly in neighborhoods where slick conditions may develop this evening.

About 900 trucks will remain on duty this evening throughout Loudoun, Fairfax, Prince William and Arlington counties.

Reminders and resources:

  • Slow down and allow for extra time to reach your destination
  • Be aware of potentially icy areas such as bridges, ramps, curves and overpasses
  • Check www.511virginia.org for road conditions
  • Get more details on snow removal in northern Virginia
  • Follow VDOT Northern Virginia on Twitter: @vadotnova

Snow falls on 3/25/14 (file photo)A mixture of rain and snow is falling on Arlington as forecasters warn of a couple of inches of accumulation through Tuesday.

The snow expected in Arlington is nothing compared to the blizzard expected in New York City and other northeastern locales  — which has prompted numerous flight cancellations at Reagan National Airport this morning.

(Students had no such luck — Arlington Public Schools started on time.)

Forecasters say Arlington might get enough snow to make tonight’s evening rush hour and tomorrow’s morning rush hour a bit tricky.

The National Weather Service has issued the following Winter Weather Advisory for the region.

… WINTER WEATHER ADVISORY NOW IN EFFECT UNTIL 10 AM EST TUESDAY…

* PRECIPITATION TYPE… SNOW.
* ACCUMULATIONS… 2 TO 4 INCHES.
* TIMING… SNOW WILL MIX WITH RAIN AT TIMES THROUGH MID-AFTERNOON. PRECIPITATION WILL CHANGE TO ALL SNOW LATE THIS AFTERNOON. THE HEAVIEST SNOW IS EXPECTED TONIGHT BEFORE ENDING TUESDAY MORNING.
* TEMPERATURES… IN THE LOWER 30S.
* WINDS… NORTHEAST 10 TO 15 MPH TODAY… BECOMING NORTH TONIGHT INTO TUESDAY WITH GUSTS AROUND 25 MPH.
* IMPACTS… ROADS WILL BE SNOW COVERED AND SLIPPERY WITH VISIBILITIES BEING REDUCED TO NEAR ONE-QUARTER MILE AT TIMES. THE COMBINATION OF SNOW COVERED ROADS AND LOW VISIBILITY WILL MAKE TRAVELING DANGEROUS

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A WINTER WEATHER ADVISORY FOR SNOW MEANS THAT PERIODS OF SNOW WILL CAUSE PRIMARILY TRAVEL DIFFICULTIES. BE PREPARED FOR SNOW COVERED ROADS AND LIMITED VISIBILITIES… AND USE CAUTION WHILE DRIVING.

In preparation for the snow, AAA Mid-Atlantic issued a press release urging drivers to be careful on the roads. The automobile association went so far as to admit that “most Washingtonians really don’t know how to drive in the snow.”

From AAA:

… watch out on unplowed side streets in residential areas, and slow down when approaching ramps, culverts, bridges and elevated overpasses, which tend to freeze first and thaw last…

If you are out there, avoid passing snowplows or salt trucks unless it is absolutely safe and necessary. If you have to go, drive in cleared lanes. Changing lanes unnecessarily puts you at greater risk of hitting a patch of ice or large areas of snow between lanes that could easily cause you to lose control of the vehicle.

It is an old joke, but it rings so true. Most Washingtonians really don’t know how to drive in the snow. First of all, if you don’t have to venture out, stay put and delay your commute. If you are a federal worker, stay alert for current operating status announcements from the U.S. Office of Personnel Management (OPM). Secondly, if you must go, reduce your driving speed to a third of your normal pace, and keep your low beams on. Thirdly, give the car ahead of you extra space. Stay at least one car length behind it for every 10 miles per hour on your speedometer, and anticipate turns and possible stops.

Fourthly, be sure to carry a cold weather emergency kit outfitted with jumper cables, first aid kit, a few tools, a shovel, sand, kitty litter, or traction mats, a flashlight with extra batteries, emergency flares or reflectors, and a fully-charged cell phone with a car charger. Then pack some essential supplies including blankets, food, and water to comfort you–and possibly save you–if you’re delayed or stranded in a snowstorm.

Winter storm hits Arlington Jan. 6, 2015(Updated at 6:20 p.m.) The National Weather Service has issued a winter weather advisory for tomorrow, Wednesday, from 6:00 a.m. to 6:00 p.m.

The advisory calls for 1-3 inches of snow in the D.C. metro area, with the flakes starting to fall tomorrow morning and continuing through the afternoon, possibly affecting the evening rush. The heaviest snow is predicted to fall in the late morning and early afternoon.

Although temperatures are hovering in the mid-to-high-40s this afternoon, they’re expected to drop to right around freezing overnight. The weather could prove tricky for morning commutes and school buses.

The Washington Post’s Capital Weather Gang says the 1-3 inch prediction is likely “overdone” but a band of stronger snow in areas is possible.

Arlington Public Schools is not likely to make a decision on a delay or cancellation until early Wednesday morning. The National Weather Service issued a similar winter weather advisory prior to the Jan. 6 snowfall that caused numerous traffic issues, leading APS to issue an apology the next day for not delaying the start of school.

According to the Arlington Dept. of Environmental Services spokeswoman Jessica Baxter, snow crews are on alert, “hooking up trucks today and will be prepared to brine streets early tomorrow morning.”

The National Weather Service is warning that falling temperatures overnight may cause Monday’s rain to freeze and become Tuesday morning’s ice.

The refreeze could make the morning commute treacherous. From NWS:

… SUB-FREEZING TEMPERATURES OVERNIGHT WILL CAUSE UNTREATED SURFACES TO RE-FREEZE…

TEMPERATURES WILL BE FALLING STEADILY OVERNIGHT BEHIND A COLD FRONT. OVERNIGHT LOWS ARE EXPECTED TO REACH THE UPPER 20S AND LOWER 30S ACROSS THE REGION BY THE PREDAWN HOURS. A STEADY BREEZE FROM THE NORTH WILL DRY OUT SOME SURFACE AREAS LATE TONIGHT. HOWEVER… ANY STANDING WATER LEFTOVER ON UNTREATED SURFACES IS EXPECTED TO FREEZE.
DRY AND COLD NORTH WINDS WILL REMAIN OVER THE AREA INTO THE MORNING HOURS ON TUESDAY… KEEPING TEMPERATURES NEARLY LOCKED INTO NEAR FREEZING RANGE. BE ALERT FOR THE POSSIBILITY OF PATCHES OF ICE WHILE DRIVING OVERNIGHT AND DURING THE MORNING COMMUTE ON TUESDAY.
