Snow plow progress on Thursday afternoon, via MCDOT

Plow truck operators were trying to keep main roads as clear as possible as heavy snow fell throughout the area on Thursday afternoon.

Between 1 and 2 inches of snow was falling per hour during the heaviest periods of the snowfall, with 3.5-5 inches reported throughout the Bethesda and Chevy Chase area around 2 p.m.

Montgomery County plow crews haven’t started plowing primary neighborhood or neighborhood roads. The Highway Services Division’s plow progress can be monitored on MCDOT’s website.

Officials are urging residents to stay off the roads if possible. If you must drive, MCDOT has a warning:

Updated at 12:35 P.m. – Montgomery County Public Schools and county government buildings are closed on Thursday due to the snow that’s expected to continue into Thursday afternoon.

The school system made the announcement at 4:25 a.m.:

Montgomery County Public Schools and all administrative offices are closed today due to emergency weather conditions. All school and community activities in school buildings are canceled.

The Montgomery County government is also closed Thursday, meaning county buildings are closed and trash and recycling pick-ups moved back one day. Parking in county garages and lots is free. Here’s the official county announcement:

Montgomery County Government is closed today, Thursday, March 5. Essential personnel must report at their regularly scheduled times. County facilities, other than Public Safety facilities, are closed.

County provided recycling and trash collections for Thursday residents have been postponed untilFriday March 6 due to the approaching snow storm. Friday residents will be serviced on Saturday March 7th.

For more information about closings and snow-removal operations, visit the county’s snow information website at www.montgomerycountymd.gov/snow.  Residents can also call 311 or 240-777-0311. The MC311 call center will remain open all night and throughout the day Thursday.

NWS snow prediction map, Via NWS

Heavy snow is forecast for the area on Thursday, and a Winter Storm Warning is in effect from late Wednesday night to Thursday night.

The key numbers: 6-10 inches. That’s the amount of snow accumulation the National Weather Service is predicting for Montgomery County.

Most of that snow will likely come from mid-morning Thursday to mid-afternoon.

Montgomery County Highway Services, the people who plow county roads, will activate the county’s Storm Operations Center at midnight.

County plows could have company from some of the 2,700 government personnel and contractors the State Highway Administration will have operating throughout the storm. That includes 2,400 pieces of equipment statewide. To date, the SHA has spent $95 million on winter operations and used 285,000 tons of salt.

The state will also put out six heavy-duty tow trucks on highways in the Baltimore and D.C. metro regions, in anticipation of disabled tractor trailers.

As for Metro, Metrobus service will be on a Moderate Snow Plan Thursday, meaning some routes will be suspended. Metrorail will operate as scheduled, though weather-related delays might happen.

Metro will have 771 employees assigned to snow-clearing efforts with 2,300 tons of salt ready to use on Metro roadways and parking lots. The transit agency also has 400,000 pounds of de-icer for sidewalks, station entrances and platforms. It claims it has 251 squeegees.

Jurisdictions such as D.C. and the City of Rockville have already declared Snow Emergencies for tomorrow. We’ll update this post if Montgomery County does the same.

Via MCPSAs for a school closing, MCPS typically releases its snow day decisions shortly before 5 a.m. the day of storms.

But the school system will occasionally act before any snow hits the ground on the nights before expected snow events. It cancelled school for Feb. 17 on the night of Feb. 16. About 3.5 inches of snow fell in Bethesda, though other areas of the county saw more accumulation.

If school is cancelled Thursday, some students may not be happy for too long. MCPS has already had five no-school days because of weather, one more than the four inclement weather days built into the calendar.

A snow day Thursday (and another potentially coming on Friday) could mean two or three days are added to the school year in mid-June.

The National Weather Service has put the Bethesda area and much of the D.C. area under a Wind Chill Advisory and Winter Weather Advisory.

The Winter Weather Advisory will go into effect at 2 p.m. Wednesday, ahead of what’s expected to be a brief period of heavy snow that could bring up to an inch of accumulation.

Making that accumulation happen will be the continued freezing temperatures. The Wind Chill Advisory is actually for Wednesday night and early Thursday morning, when the wind chill is expected to dip between 5 and 15 degrees below zero.

The temperature is forecast to reach 30 degrees before the snow squalls come sometime between 3 p.m. and 8 p.m. Wednesday:

…WIND CHILL ADVISORY IN EFFECT FROM MIDNIGHT TONIGHT TO 6 PM EST THURSDAY…

With more bitter cold expected this weekend, Montgomery County is reminding residents to watch out for children, senior citizens and homeless individuals who might be particularly vulnerable.

The National Weather Service has issued a High Wind Watch for the entire region and much of the weekend:

…HIGH WIND WATCH REMAINS IN EFFECT FROM SATURDAY EVENING THROUGH SUNDAY MORNING…

* TIMING…NORTHWEST WINDS WILL INCREASE BEHIND A STRONG COLD FRONT SATURDAY EVENING THROUGH SUNDAY MORNING.

* WINDS…NORTHWEST 25 TO 35 MPH WITH POTENTIAL FOR WIND GUSTS UP TO 60 MPH.

* IMPACTS…DOWNED TREES AND POWERLINES MAY RESULT IN POWER OUTAGES. MINOR STRUCTURAL DAMAGE WILL BE POSSIBLE. DRIVING HIGH PROFILE VEHICLES IN THESE CONDITIONS WILL BE DANGEROUS.

As of Friday afternoon, NWS had issued a Wind Chill Advisory for northern Montgomery County, though downcounty Montgomery could certainly get its own advisory with wind chills expected to dip below zero on Saturday night.

Montgomery County is offering its facilities, such as libraries, recreation centers and senior centers, as a place to find warmth during regular operating hours. The county government also suggested public shopping centers as an option.

Homeless outreach providers are trying to encourage homeless people to seek shelter and all emergency and transitional shelters in the county will allow homeless individuals to stay inside until it gets warmer.

The county is also asking residents who notice signs of hypothermia to take that person’s temperature.

“If it is below 95 degrees, the situation is an emergency — get medical attention immediately,” according to a county press release on Friday. “If the person is unconscious and does not seem to have a pulse or to be breathing, call 9-1-1.”
