Europe Tactical (UPDATE): Alerts for adverse weather issued in multiple countries, disruptions ongoing in Nordics due to Storm Hannes on December 28; remain abreast of updates
Current Situation
- Authorities in multiple countries have issued alerts and warnings for inclement weather conditions on December 28. Details of which are as follows:
- In Finland, Norway, and Sweden, winter storm Hannes has prompted widespread transport and utility disruptions, driven by strong winds, heavy snow, and ice. Power outages have affected more than 120,000 households in Finland, over 40,000 households in Sweden, and over 32,000 households in Norway, primarily due to downed power lines and storm-related infrastructure damage. In Finland, operations at Kittila Airport (KTT) were temporarily suspended on December 27 after strong winds pushed two aircraft off the runway into a snowdrift.
- Additionally, two fatalities linked to the storm were recorded in Sweden on December 27.

Assessments & Forecast
- Adverse weather impacts are expected to persist in affected countries through at least December 29, with the Nordics facing the highest risk of continued disruption from strong winds, snow, ice, and sub-zero temperatures, while southern Europe remains exposed to flooding and landslide risks.
- Transport disruptions are likely to continue in the aforementioned areas, particularly affecting road and rail networks due to black ice, snow accumulation, and wind-related infrastructure damage. Localized aviation delays and temporary airport suspensions remain likely, especially at regional airports in the Nordics, including northern Finland, northern Sweden, and coastal Norway, as evidenced by the disruptions recorded at KTT in Finland.
- Utility disruptions, particularly power outages, are expected to be restored unevenly, with rural and forested areas remaining vulnerable to prolonged outages and secondary failures as weather conditions fluctuate.
- Residual disruptions, including traffic accidents, falling trees, and infrastructure damage, are expected to persist in the coming days.
Recommendations
- Those operating or residing in the aforementioned countries in Europe on December 28 and in the coming days are advised to remain abreast of the authorities’ updates regarding weather-related risks.
- Allot for travel disruptions, including delays or cancellations of rail, flight, and public transport services due to inclement weather conditions across the affected areas.
- Charge essential electronic devices such as cellular phones, laptops, and tablet computers ahead of the planned power outage, and initiate energy-saving functions on these devices as needed.
- Disconnect all surge-prone devices such as computers, televisions, and appliances to prevent potential damage.
