Meteorologist Nils Holmqvist from SVT explained that the time of year exacerbates the situation, as trees lack the stability of a fully developed root system and foliage. The combination of strong winds and rainfall has proven especially risky, leading to an increased number of tree falls.

A tree also fell onto the Green Line subway at 3:00 PM local time, causing subsequent delays even after its removal. Additionally, the Spårväg City tram line between Skansen and waldemarsudde is completely halted due to obstructions on the tracks. Roslagsbanan, another key rail line, is also fully closed because of fallen trees.

Power Outages Affect Thousands

multiple locations throughout Stockholm County are suffering from power outages. Erik Elowsson, a press officer at Telge, attributed the disruptions to trees falling onto power lines.

Impact Across Stockholm County

Stockholm County experienced critically importent disruption today, September 12, 2025, as exceptionally strong winds swept across the region. Reports are flooding in of fallen trees, damaged roofs, and widespread power outages. The Swedish Meteorological and Hydrological Institute (SMHI) had issued a yellow warning for strong winds earlier this week, but the intensity of the gusts appears to have exceeded initial forecasts. Areas particularly affected include the coastal communities of Norrtälje and Vaxholm, as well as inland regions around Uppsala and Södertälje.

Damage Reports – A Regional Breakdown

* Norrtälje: Numerous reports of uprooted trees blocking roads,hindering emergency vehicle access. Ferry services to the archipelago have been temporarily suspended due to hazardous sea conditions.

* Vaxholm: Significant roof damage reported in the town center,with debris posing a risk to pedestrians. Several historical buildings are undergoing assessment for structural integrity.

* Uppsala: power outages affecting thousands of homes and businesses. Uppsala University has cancelled afternoon classes as a precautionary measure.

* Södertälje: Fallen trees have caused disruptions to public transportation, including train and bus services. Scania AB, a major employer in the area, temporarily halted operations at its production facility.

* Stockholm City: While the city center escaped the worst of the damage, several parks have been closed due to falling branches and hazardous conditions.

Understanding the Storm – Wind Speeds and Causes

The strong winds are attributed to a deep low-pressure system moving across the Baltic Sea. SMHI recorded peak wind gusts of up to 28 m/s (approximately 63 mph) in exposed coastal areas. These speeds are considered dangerous and capable of causing considerable damage. The combination of strong winds and saturated ground, following recent rainfall, has increased the risk of trees being uprooted. This weather event is categorized as a windstorm, a common occurence in Scandinavia during the autumn and winter months.

Key Wind Speed Classifications (SMHI)

Wind Speed (m/s) Description Effects
8-10 Light Breeze Small twigs move, flags flutter
11-13 Gentle Breeze small branches move, dust rises
14-17 Moderate Breeze Large branches move, whistling in ears
18-20 Fresh Breeze Small trees sway, challenging walking
21-24 Strong Breeze Large trees bend, some damage possible
25-28 Gale Significant damage, widespread disruption
29+ Strong Gale/Storm Severe damage, dangerous conditions

Power Outages and Emergency Services response

Electricity provider Ellevio is working to restore power to affected areas, but estimates suggest that some customers might potentially be without electricity overnight.The Swedish Civil Contingencies Agency (MSB) has activated its emergency response plan, coordinating efforts between local authorities, emergency services, and utility companies.

Residents are urged to:

  1. Stay indoors: Avoid unneeded travel during the storm.
  2. secure loose objects: Bring in outdoor furniture, decorations, and anything else that could be blown away.
  3. Report damage: Contact your local municipality to report fallen trees, damaged property, or power outages.
  4. Check on vulnerable neighbors: Ensure elderly or disabled neighbors are safe and have access to essential supplies.
  5. Avoid coastal areas: Stay away from beaches and harbors due to the risk of high waves and strong currents.

Historical Precedent: The 1990 Storm and Lessons Learned

Sweden has a history of severe windstorms. The most devastating in recent memory was the storm of January 1990,which caused widespread damage across southern Sweden,resulting in nine fatalities and billions of krona in damages. Following the 1990 storm, significant investments were made in strengthening the electricity grid and improving forest management practices to reduce the risk of future damage. these improvements have demonstrably helped mitigate the impact of subsequent storms, but today’s events highlight the ongoing vulnerability of infrastructure to extreme weather events.Forestry management and infrastructure resilience are key areas of focus for ongoing preparedness.

Practical Tips for Protecting Your Property

* Tree Maintenance: Regularly prune trees on your property to remove dead or weak branches.

* Roof Inspection: Have your roof inspected annually for loose tiles or other potential vulnerabilities.

* Secure Outdoor Items: Invest in securing outdoor furniture and other items that could be blown away by strong winds.

* Emergency Kit: Prepare an emergency kit with essential supplies such as food, water, a flashlight, and a first-aid kit.
