Snowstorm to Sweep Through New Hampshire Before Christmas – A Travel Advisory You Need to Know

Published on December 23, 2025

New Hampshire is preparing for a significant winter weather event as snow moves in ahead of Christmas. The National Weather Service has issued warnings for potential disruptions to travel, with up to six inches of snow forecast for the state, particularly in the northern regions. Travelers are advised to remain cautious and prepared for slippery roads, especially during the afternoon and evening on Tuesday, December 23, 2025.

With the holiday season in full swing, this snowfall is expected to create delays and slowdowns, particularly for commuters and holiday travelers. As snow falls steadily across New Hampshire, the conditions are likely to impact both road and air travel, creating hazards for those traveling by car or plane.

Snowfall Timing and Areas Impacted

The snowstorm is expected to arrive on Tuesday afternoon, with conditions worsening by the evening. Areas in central and southern New Hampshire can expect 1-3 inches of snow, while the northern region, including the White Mountains and North Country, may see 3-6 inches. The worst of the storm will occur in the late afternoon and evening hours, coinciding with the evening commute, which could become slow and hazardous.

Meteorologists predict that although the snow will not be a major storm, it will cause slippery roads and low visibility at times. With wind gusts of up to 30 mph on Monday, and snow starting to fall by Tuesday afternoon, travelers are encouraged to plan for extended travel times. The snow will taper off by Wednesday morning, but conditions could remain slippery into Christmas Eve.

Impacts on Travel

Given the timing of the storm, many travelers are expected to encounter delays on their way to and from their destinations. Snowfall can create challenging driving conditions, particularly on highways. The National Weather Service advises motorists to avoid travel unless absolutely necessary, especially as snow accumulation could make roads slippery and hazardous.

The storm will also affect air travel in and out of New Hampshire. New Hampshire’s largest airport, Manchester-Boston Regional Airport (MHT), could experience delays and cancellations as planes are grounded due to low visibility. Travelers are advised to check flight statuses before leaving for the airport, as snowstorms and low visibility can result in flight delays or cancellations. The storm’s timing could also affect those traveling on long-haul flights, with secondary delays due to backup at airports in nearby cities.

Weather Forecast and Travel Tips

According to the National Weather Service, temperatures on Tuesday will remain below freezing, making the snow and ice conditions particularly dangerous. Winds will pick up, which will compound visibility issues and make driving even more treacherous. The weather service has issued an advisory for areas along Route 93 and Route 89, both of which are key travel routes in the region. Additionally, travelers on roads like Route 101 and Route 4 may experience increased delays due to snowy conditions.

To stay safe, the National Weather Service recommends the following travel tips for New Hampshire residents and visitors:

1. Allow extra travel time: With snow and wind complicating road conditions, it’s best to leave early for any appointments or flights.
2. Use a vehicle that’s ready for winter weather: Ensure your vehicle has snow tires or chains if needed, and check your brake lights, wipers, and antifreeze levels.
3. Monitor road conditions: Check for road closures or accidents through local news, the New Hampshire Department of Transportation, or your GPS navigation app.
4. Dress warmly: If you get stuck in traffic or stranded, ensure you have enough blankets, food, and water to keep warm.

Weather Conditions for Christmas Week

While the snowstorm will subside by Wednesday morning, weather forecasts predict more sporadic showers and cooler temperatures throughout the Christmas week. The National Weather Service is keeping an eye on further developments, with the possibility of another storm arriving on Christmas Eve. However, the storm expected at the start of the week should be the largest, and by Christmas, conditions should improve.

While snow and rain have the potential to continue affecting the region, those traveling during the holiday season can expect a clear and cold Christmas Day. However, travelers should be aware of potential delays due to weather as the storm moves out of the region.

What Travelers Should Do Now

For those planning to travel in and out of New Hampshire, it is critical to stay up to date on weather developments. Since this storm is expected to disrupt both road and air travel, staying informed is crucial for avoiding significant delays. Plan your routes ahead of time and account for potential diversions or detours due to road conditions.

If you’re traveling by air, consider arriving early at the airport to account for any weather-related delays. For those flying in or out of the Manchester-Boston Regional Airport (MHT), consider using apps like FlightAware to track your flight’s status. If traveling by car, ensure you have a full tank of gas, emergency supplies, and a winter kit including a flashlight, food, blankets, and a phone charger.

What to Expect in the Days Leading to Christmas

While the snowfall will taper off by Christmas Eve, some residual effects may still linger on Christmas Day. With the possibility of icy roads in some areas and cool temperatures, drivers should remain vigilant. Also, with the storm’s aftermath expected to clear, visibility should improve for air travelers, but some residual delays could still affect holiday flights.

The good news is that with calmer conditions expected in time for Christmas Eve, those who are able to adjust their travel schedules will be in better shape to celebrate the holiday without further delay.

Conclusion

New Hampshire is facing a significant winter storm just before the Christmas holidays, causing potential disruptions to both road and air travel. With snow expected to accumulate between 1-6 inches in some areas, and winds gusting up to 30 mph, those traveling should prepare for extended delays. The good news is that conditions will begin to clear up by Wednesday, offering travelers a smoother Christmas Eve and Christmas Day travel experience.

For those traveling through New Hampshire during this time, it is highly recommended to monitor weather conditions closely, arrive early at airports, and allow extra time for road travel to ensure a safe and timely arrival. With careful planning and awareness, travelers can still enjoy the holiday season in New Hampshire despite the challenges presented by the weather.
