Met Office issues new 18-hour snow warnings for England — a practical guide to the full list of areas and what this means for you

Winter isn’t just a season; it’s a reminder that the weather likes to throw curveballs. This week, the Met Office upgraded its warnings to cover an 18-hour window, turning the region into a patchwork of caution flags. One warning stands out for its urgency: a rare amber alert that begins in the small hours of Thursday, November 20, targeting North East England. If you’re wondering what this means for your commute, your weekend plans, or how to keep your home warm, you’re in the right place. Let’s break down what’s going on, where the highest risks lie, and how you can stay safe and prepared as the snow starts to fall.

Think of this as a weather warning you don’t want to ignore, because it’s not just a few flurries. Forecasters expect frequent wintry showers to move inland from the North Sea, piling up snow in elevated places and creating conditions that can slow travel and complicate daily routines. The forecast mentions significant accumulations in upland zones such as the North York Moors and parts of the Yorkshire Wolds, with some areas potentially collecting between 15 and 25 centimeters by the time Thursday ends. Gusty winds could also whip the snow into drifts, producing what forecasters call “occasional blizzard conditions,” and there’s even a small chance of a few lightning strikes in bursts of intense snowfall. These are signals you don’t ignore; they’re a heads-up to plan ahead.

As we navigate the ever-changing weather, staying informed and prepared is more important than ever. If you’re thinking about safety, travel, or keeping your home comfortable during a cold snap, you’re not alone. In this guide, we’ll map out the affected areas, what to expect in daily life, and practical steps to stay warm and safe. We’ll also touch on heating system upkeep, because a winter cold snap is like a stress test for boilers and radiators. And if you’re looking for trusted local support, you’ll find friendly recommendations along the way, including considerations for services like Harrow Heating and Powerflush when appropriate.

What the new warnings mean in practice

First, let’s translate the forecast into practical terms. An 18-hour warning means the weather could change rapidly over a single day, with snow arriving and accumulating in a relatively short span. An amber alert is a notch above the standard warning level, signaling a higher likelihood of significant disruption and urging people to take action to protect themselves and their property. In this case, the amber warning is specifically focused on North East England and begins at 3am on Thursday. If you live in or near that area, you’ll want to be extra vigilant in the pre-dawn and morning hours and monitor updates as conditions evolve.

The core concerns are heavy, persistent snowfall and strong winds that can push the snow into uneven drifts. When snow piles up on hills and elevated ground, it creates more pronounced travel hazards, including reduced visibility and slick surfaces. The combination of snow with wind can cause local blizzard-like conditions, where visibility drops and roads become harder to navigate. Lightning is not common in snow squalls, but meteorologists note that even a few lightning strikes can occur in intense bursts. So while lightning is not the main threat, it’s part of the broader weather variability we could see on Thursday.

From a practical standpoint, the warnings are telling people to anticipate possible travel delays, plan for extra time, and consider staying indoors in worse conditions. Schools and workplaces may adjust schedules, especially for rural routes or areas with hillier terrain. If you rely on public transport or commute through exposed routes, now’s the moment to check live travel updates and leave a little earlier than usual if you must travel. And if you’re a homeowner, use this window to prep your heating and home for a cold snap that could persist beyond Thursday.

Where the snow is likely to hit hardest

The forecast highlights upland and exposed areas as the main battleground for snow accumulation. While the warnings cover broad parts of England, the most notable hotspots include:

  • North East England – The amber warning centers on this region, with the strongest impacts anticipated in the early hours and morning as snow bands move in from the North Sea.
  • North York Moors – A highland, moorland landscape where snow tends to settle first and persist, leading to significant depth on exposed slopes.
  • Yorkshire Wolds – Rolling hills and elevated farmland can see meaningful accumulations, creating white-covered horizons and tricky driving conditions on secondary roads.
  • Adjacent upland corridors – While the most intense snow is forecast for these zones, if you live in nearby elevations or rural pockets, you could still experience heavier flurries that affect day-to-day routines.

Forecasts indicate accumulations of roughly 15–25 cm on hills above about 100 meters in elevation as Thursday unfolds, with the snow lingering into the late afternoon or evening. It’s important to note that lower-lying towns and cities may see lighter snow or a wintry mix, but accumulations can still cause slippery conditions on untreated surfaces. The net takeaway is to expect a mix of heavy bursts and lighter periods, with the potential for drifting snow on exposed lanes and unplowed routes.

When a snow event of this scale approaches, life tends to slow down a notch. Roads ice up, and drivers must adapt. In the countryside, single-track lanes can become blocked by drifted snow, while in towns, side streets may be plowed late or not at all if the snowfall intensifies in the small hours. Schools in affected districts often reassess opening times, with some operating on a delayed schedule as a precaution. Commuters who usually rely on trains or buses may experience cancellations or delays, particularly if lines run through the exposed North York Moors corridor or routes impacted by snowfall and wind gusts.

For people who work from home or in flexible roles, Thursday could be a day to adjust plans around weather windows. And if you’re responsible for vulnerable friends or family, it’s wise to check in early and ensure they have enough essential supplies on hand and a plan for staying warm indoors.

From a safety perspective, the combination of cold temperatures, snow, and wind raises the risk of slips and falls on icy pavements. Pedestrians should wear appropriate footwear with good grip, take shorter steps to maintain balance on slick surfaces, and give yourself extra time for outdoor trips. If you use a vehicle, pre-plan routes, keep a chargeable phone, and maintain at least a half-tuel of fuel in case you get stuck or delayed. The Met Office also recommends closely following local updates, including any travel advisories issued by local authorities or transport providers.

Keeping your home warm and your heating efficient this winter

A cold snap is a good reminder to check your heating setup. When temperatures drop, heating systems work harder, and tiny inefficiencies can become noticeable quickly. Here are practical steps you can take right now to keep your home warm without breaking the bank:

  • Check your boiler and controls – Make sure your boiler is firing correctly and that thermostats are calibrated. If your system seems to struggle to stay warm, it could be a sign of deeper issues that deserve a professional look.
  • Bleed radiators – Air trapped in radiators can prevent them from heating evenly. A quick radiator bleed can improve comfort and efficiency.
  • Insulate and seal – An extra layer of draught-proofing around doors and windows and insulating pipes can prevent heat from leaking out and keep rooms warmer for longer.
  • Set reasonable temperatures – It’s tempting to turn the heat up full blast, but a steady, moderate warmth is often more efficient than blasting heat briefly after every cold spell.
  • Consider system cleaning – If your radiators feel sluggish or you notice cold spots, a system flush can remove sludge and improve circulation. This is where specialist services come in—think about speaking with local experts who can assess your setup.

If you’re weighing your options, you might explore services like Harrow Heating for a professional boiler check, service, and advice on staying warm through the season. A well-tuned heating system runs more efficiently, uses less energy, and keeps your home comfortable on those long, cold nights. And for homeowners whose systems have collected sediment or sludge over time, a targeted powerflush from Powerflush can help restore full heating performance by clearing the sludge that builds up in radiators and pipes. It’s the kind of proactive step that pays off when the deep freeze arrives and you want a reliable, even heat throughout the house.

What to do next: practical steps for the next 24 hours

Here’s a simple, action-oriented checklist you can follow to stay one step ahead of the weather. Treat this like a mini-weather emergency plan—practical, not panic-driven:

  • Stay informed – Monitor daily updates from the Met Office or your local weather service. Weather can shift quickly, and new advisories may refine the area impacted and the timing.
  • Travel decisions – If you can, shift to non-urgent travel to before the worst of the weather arrives, especially overnight and in the early morning. If you must drive, prepare a winter car kit and adjust your speed to road conditions.
  • Stock up responsibly – Ensure you have a small supply of essentials (food, water, medications) in case you’re snowed in or travel is disrupted for a day or two.
  • Protect the home – Close curtains at dusk to retain heat, and keep a spare set of warm clothes for anyone who might be cold indoors.
  • Look after vulnerable people – Check on neighbors and relatives who may need extra warmth, food, or assistance during a cold spell.

When it comes to planning, think of the weather as an unpredictable guest. You don’t know when it will arrive, but you can set the table for comfort and safety in advance. If you want dependable heating advice during this period, you can reach out to local specialists for a quick check or guidance—reliable services like Harrow Heating are often ready to help, and for deeper heating system cleaning, Powerflush offers professional options to restore peak performance.

Staying safe outdoors: driving, walking, and outdoor activities

Snow, ice, and wind create a three-way hazard for outdoor activity. If you’re driving, plan routes that avoid steep hills and ungritted back roads. Allow extra time and keep a safe following distance—stopping distances increase significantly on icy surfaces. For pedestrians, sturdy footwear with good tread and careful stepping will help avoid slips. In open areas like the North York Moors, it’s wise to check wind chill and visibility and avoid exposed peaks during gusty conditions.

If you’re temporarily unable to get to work or school because of the weather, it’s worth contacting your employer or school early to communicate your situation. Most organizations appreciate proactive communication when travel might be hazardous. And if you’re a parent arranging activities for children, consider indoor alternatives on the days when the cold intensifies.

Outdoor enthusiasts who enjoy hill walking in upland areas should be prepared for rapidly changing conditions. If you’re set on venturing out, tell someone your route and expected return time, carry a charged phone, a small emergency kit, and keep to marked paths, especially where snow can obscure hazards beneath the surface.

Monitoring the forecast: what to expect next

The Met Office’s extended 18-hour warning signals that this isn’t a one-off snapshot; the weather pattern is likely to evolve through Thursday. After the amber alert begins, forecasters will continue to monitor how the snow bands behave as they move inland and how much accumulates on the hills. While the strongest impacts are forecast for North East England and upland zones, keep in mind that gusty winds and flurries can spill into neighboring areas with flurries or brief heavier bursts in rural pockets. It’s a good idea to stay tuned to updates through the day and adjust plans as new information comes in.

To stay ahead of changes, set up alerts on reliable weather apps, bookmark official Met Office pages, and follow local news outlets for transport advisories. If you’re preparing your home or equipment for the cold, remember that small, proactive steps now can prevent bigger headaches later in the week. For homeowners who want extra reassurance about their heating system, consider a professional check from Harrow Heating and a potential Powerflush if your radiators feel sluggish or uneven in heat distribution.
