‘Deteriorating conditions’ and ‘impassible roads’: DC region faces first major snowstorm of 2025

The first major snowstorm to hit D.C., Maryland and Virginia this year is bringing heavy snow and teeth-chattering, below-freezing temperatures. Here’s what you need to know.

A winter storm warning, issued by the National Weather Service, went into effect for the D.C. area at 10 p.m. Sunday. It is set to expire at 1 a.m. Tuesday.

WTOP Meteorologist Lauryn Ricketts is forecasting anywhere between 6 inches and a foot of snow accumulation across the region, by the time this storm has passed.

“Snow will lighten up in intensity through the midday hours. However, the main part of this storm will sweep overhead this evening,” Ricketts said.

A second dose of winter weather this afternoon may mean a few additional inches of snow, pushing expected totals over 5 inches for most of the area.

“Whatever falls, it’s likely to stick,” 7News First Alert Meteorologist Mark Peña said.

The National Weather Service said it expects the weather to pick up over the early morning hours, putting a damper on Monday travel for all of the national capital region.

“Expect travel conditions to continue to deteriorate with snowfall rates of an inch or more per hour over the next several hours,” the weather service said early Monday.

Officials at the National Weather Service said they expect heavier snow to depart from west to east between 5 a.m. and 10 a.m. Later snowfall is likely to mix with sleet and freezing rain before much of the snowstorm finishes up at around 9 p.m.

Given the growing snow totals, 7News First Alert Chief Meteorologist Veronica Johnson said the storm could mark the region’s biggest snow event since 2019.

“The last time we had 11 inches was on Jan. 23 of 2016. … That storm delivered a total of 17.8″ of snowfall that ended the following day,” Johnson said Sunday evening.

Johnson said there is a 90% chance much of the D.C. area will see somewhere between 6 and 9 inches of snowfall — the last time the area saw half a foot of snow was in January of 2022.

Temperatures on Monday will remain below freezing, staying in the upper 20s with wind speeds between 5 mph and 10 mph. Johnson said the area could be facing some road closures and power outages toward the evening hours.

“Here’s why I think yes: There will be a little bit of sleet — we mentioned that’s basically just some iciness, right — but then the wind will start picking up late Monday and throughout the day on Tuesday. And I really think it’s late Monday, early Tuesday when we can see our higher number of power outages because of the winds,” Johnson said. “Our winds could be gusting around 35 to 40 miles per hour”

Once the snow wraps, expect chilling winds to stick around. Forecasters said highs will remain in the 20s through the end of the week. The weekend will see a slight temperature rise to the 30s.

Closures continue across DC, Maryland and Virginia

Multiple school districts and government offices across the region announced closings, delays and other scheduling modifications in anticipation of the snowstorm. Monitor the latest changes on WTOP’s Closings & Delays page.

D.C. Mayor Muriel Bowser declared a snow emergency through the end of Tuesday. The decision activates several snow-related emergency powers, including the right to tow any cars parked along emergency snow routes during the storm.

To avoid getting your vehicle removed, check out the marked routes on the D.C. government website.

In addition, D.C. residents with animal emergencies should reach out to the Brandywine Valley SPCA.

In Maryland, Gov. Wes Moore declared a state of emergency that took effect Sunday and is set to last through at least Monday.

“Keeping Marylanders safe is our top priority. Please stay off the roads during this storm. Prepare your home and family and charge your communications devices in case you lose power” according to a news release from Moore’s office.

“Immediate actions are being taken to safeguard Marylanders. Law enforcement agencies are increasing staffing, with support standing by as needed, while public health, human services and utilities agencies continuously prepare for possible impacts from the storm,” his office said.

In Virginia, Gov. Glenn Youngkin took similar steps and declared a state of emergency. Officials with the Virginia Department of Transportation advised travelers to stay off the roads.

“I’m encouraging all Virginians, visitors, and travelers to stay alert, monitor the weather forecast, and prepare now for any potential impacts,” Youngkin said.

Traffic concerns mounting ahead of morning commute

Officials have declared emergencies in the District, Maryland and Virginia following statements from the National Weather Service that traveling by car “could be very difficult.”

“Roads, and especially bridges and overpasses, will likely become slick and hazardous,” the National Weather Service said.

Monday morning Metro officials announced a change to their plans for Metrobus and rail services around the D.C. area, moving to a “severe snow plan due to deteriorating conditions and impassible roads on several routes.”

“Under this plan, 42 out of 193 bus routes will operate. As road conditions change throughout the day, service may be reduced further or added back as needed,” WMATA said.

More information on which routes are impacted and the services available are listed on the WMATA severe weather page.

DC Department of Transportation Director Sharon Kershbaum told WTOP crews in the District have been working throughout the early hours of the morning to treat and clear snow-covered roads around the city.

“Please if you don’t need to travel don’t travel. Stay home. … If you do need to travel drive safely, drive slowly,” Kershbaum said.

Virginia Department of Transportation spokesperson Alex Liggitt also said the department is advising people in the Commonwealth to avoid travel on Monday, if possible.

“If you do not need to be out there — if you’re a nonessential worker — just please stay off the roads and really give our crews plenty of time to get out there and get as many hours in without anyone out there,” Liggitt told WTOP.

Liggitt said the lack of drivers will allow snowplows and emergency officials to continue treating area roadways without worrying about crashes and disabled drivers.

“That really helps us out, without any other incidents going on on the roads,” he said.

If you absolutely have to drive, officials suggest bringing a winter storm kit packed with tire chains, booster cables, a flashlight, blankets “and anything else that would help you survive in case you become stranded.”

The Fairfax Connector bus service in Fairfax County, Virginia, said Monday morning that it suspended operations due to the weather and “will reassess service levels later this morning.”

The Maryland Transit Administration is also encouraging passengers on area busses, trains and other forms of public transit to wear weather appropriate clothes and allow more time for travel Monday morning.

“We also encourage passengers to check out the service alerts on the MTA website,” the agency said Sunday.
