The Finnish Meteorological Institute (FMI) has warned that a fierce storm could bring damaging winds and cause power outages and disruptions to telecommunications across southern Finland between Wednesday, September 16, and Thursday, September 17. The FMI has issued a strong wind warning for all areas south of Jyväskylä (Central Finland region). Greater Helsinki will be hit by the storm in the early hours of Thursday morning, with even the strongest winds off the western coast. Winds of up to 115 kph (71 mph) are possible and over 1.5 inches (40 mm) of rain.
The FMI has advised people to prepare for the storm by canceling travel plans, stocking up on drinking water, charging mobile phones and flashlights, securing or storing any garden furniture, and closing all doors and windows. They are also advising people to stay indoors when the storm hits, away from windows, avoid using lifts, and to refrain from attempting to fix any property damage until the storm has fully passed.
Localized flooding, disruptions to transport and business, and damage caused by falling trees and flying debris are possible in the coming days.
Those in the affected areas are advised to monitor local weather reports, follow the above advice from the FMI, avoid areas directly affected by flooding, confirm road conditions before setting out, and adhere to instructions issued by local authorities.
