Washington closes for snow in a way that puzzles people from Buffalo. An inch can empty the Beltway; a forecast can cancel a day. The reason is structural: a region of commuters spread across three jurisdictions and a workforce dominated by one employer whose decision, taken before dawn, sets the pattern for everyone else. For a courier that is both the problem and the job, because the things that must move on a snow day are precisely the ones that cannot wait for a thaw — a specimen, a filing, a prescription, a signed page. This guide explains how courier deliveries work on snow days and federal closure days in Washington DC, Maryland and Virginia: how the closure decision is made, what a snow emergency means on the street, what the numbers say about the city's winters, and how we plan a storm day so that you know what is reachable before you book.
How the federal government decides by 4 a.m.
The Office of Personnel Management sets the operating status of federal offices in the Washington area, and its published protocol explains how. Around 3:00 a.m. OPM convenes a call with the Council of Governments' regional partners — the transportation agencies, emergency managers and school and road officials of the District, Maryland and Virginia — to review conditions and forecasts. Around 3:30 the OPM Director makes the decision. Around 4:00 the status goes out on OPM's website, phone message and app. OPM notes that federal, state and local authorities have looked to it for that decision for decades, which is why a federal status announcement moves the whole region's morning.
The statuses are specific. "Open" is normal. "Open with option for unscheduled leave or unscheduled telework" means offices are open and employees may stay home. "Open — delayed arrival — employees must report" sets a later start. "Federal offices are closed" is the one that empties the roads. And "shelter-in-place" exists for emergencies rather than snow. OPM's dismissal and closure procedures apply to federal agencies with offices located inside the Washington Capital Beltway; the Congressional Research Service, using OPM's workforce data for September 2024, counted 162,489 federal civilian employees in the District, 144,497 in Maryland and 147,358 in Virginia, which is the scale of the commute the decision governs.
For a courier the status is information, not instruction. A closure means federal offices are shut and the agencies' mailrooms will not receive; a delayed arrival means a recipient may not be at a desk until ten; unscheduled telework means half the offices on a route are empty and the other half are open. The first thing dispatch does on a snow morning is read the status, and the second is call the recipient.
What a DC snow emergency means on the street
The District's own response is the snow emergency, declared by the Mayor to clear the main routes for plows. Its rules are published by the DC Snow Team: you may not park on snow emergency routes while the emergency is in effect; a violation carries a $250 ticket, a $100 tow fee and $20 per day in storage. The Snow Team's job is large — a 2021 release described 882 employees clearing 2,644 lane miles of residential and commercial streets with a 296-vehicle fleet including 120 heavy and 100 light plows, and the Department of Public Works said in March 2026 that a full deployment would field roughly 200 heavy and light plows. Across the lines, the Maryland State Highway Administration maintains 18,177 lane miles with about 2,100 pieces of equipment and 386,000 tons of rock salt in 87 salt facilities, and the Virginia Department of Transportation has more than 57,000 lane miles to maintain statewide, a $220 million winter budget and more than 10,200 pieces of snow-removal equipment. Virginia's governor says plainly that VDOT clears interstates and most major primary roads first, which is why a courier's storm-day map runs along the interstates and the snow emergency routes and avoids side streets until the plows reach them.
Both states declare emergencies when a storm warrants: Maryland declared a state of emergency and liberal leave for state employees ahead of a February 2026 storm; Virginia declared one in January 2026. A state of emergency changes what the state does, not whether a private driver may be on the road, but it is the signal that the roads will be prioritized for plows and emergency vehicles and that a delivery estimate should carry hours, not minutes, of slack.
The numbers: Washington's winters are lighter than its reaction
The National Weather Service's climate record for Washington, measured at Reagan National, puts the normal seasonal snowfall at 13.7 inches under the 1991–2020 normals, and many winters fall well short of that. The exceptions are the storms everyone remembers. The 2015–16 season brought 22.2 inches, 18.8 of them in January 2016, when the blizzard of January 22–23 dropped 17.8 inches at Reagan National — tied for the fourth-greatest total on record there — with 29.3 inches at Dulles and an all-time record 29.2 at BWI. That storm closed the region for days, and it is the one every dispatcher in Washington still plans against.
The lesson of the record is that most "snow days" in Washington are ice, slush and an early-morning closure decision, not a blizzard. On those days the roads are usually passable by mid-morning on the main routes, the question is who is at work, and a courier that calls ahead delivers. On the rare real storm, nothing moves until the plows have been through, and the honest thing to say is so.
What still has to move when the city closes
Hospitals do not close. Laboratories keep receiving specimens, and the ones that run daily routes with us expect them on a storm day with a later window; the medical courier and STAT medical courier pages describe how urgent specimens are prioritized, and the temperature control post covers the cooler that has to survive a longer trip in a cold car. Pharmacies deliver to patients who cannot get out; the delivering to patients at home post covers that work. Courts set their own schedules — the DC Courts, the Maryland Judiciary and the federal courts each announce their own closures — and a filing deadline does not necessarily move because the executive branch closed, so law firms check the court's notice and call us when the clerk's office is open; the court filing deadlines post explains how each court handles weather. Closings proceed if the settlement office and the recorder are open; the real-estate closing deliveries post lists the recording windows. And businesses with a standing route — branch loops, office sweeps — decide the night before whether the route runs, and we run it.
A government shutdown is a different closure with the same question. During a lapse in appropriations, OPM's shutdown guidance says that excepted employees — those performing tasks that the law allows to continue — keep working, and the rest are furloughed; some federal offices are staffed and most are not. The courier's job is the same: confirm the recipient is in before the driver leaves. The government courier page covers agency deliveries in ordinary times.
How we plan a storm day
The night before, dispatch reviews every scheduled route and every pending booking against the forecast and calls the customers whose runs are time-bound. At four in the morning we read the OPM status and the District's snow emergency notice. Drivers with sedans are kept on plowed arterials and snow emergency routes; a van goes where a load needs one, and the multi-stop delivery page explains how a day's runs are combined so that fewer vehicles are on the road. Every estimate carries weather slack: the 1-hour buffer our dispatch board adds around each task is the starting point on a storm day, not the limit. We tell you the realistic window before you commit, we call if it slips, and we do not promise a time we cannot keep because a customer wants to hear it. If a package can wait for the plows, we say so; if it cannot, we route around the hills.
Two practical notes. Parking on a snow emergency route is not an option for a driver making a delivery, so building front doors on those routes get a quick handoff rather than a wait, and a mobile number for the recipient saves the run. And the days after a storm are often worse than the storm: side streets stay unplowed, loading zones are buried, and a delivery that was easy on Monday is slow on Wednesday. Book with a window, not a minute.
What to tell dispatch on a storm day
Whether the recipient is physically in, and until when; a mobile number; whether the package is deadline-bound or can wait for clear roads; what the package is, so we can choose sedan or van and plan temperature; and whether a standing route should run or pause. Book on the booking form or call dispatch, which runs around the clock on snow days as on every other day. The same-day delivery page explains the service options; the frequently asked questions page covers the rest.
