AN AUTUMN STORM is expected to hit parts of Southern Finland on Wednesday, Joonas Koskela, a meteorologist at Foreca, revealed to Helsingin Sanomat on Monday.
Koskela said a strong low-pressure system will deliver heavy rains to the region and raise wind speeds in the early hours of the day, possibly to levels that meet the common definition of a storm – an average wind speed of over 21 metres per second over a 10-minute period.
“It may be blowing pretty decently,” he commented.
Temperatures in Southern Finland are forecast to remain around the 10-degree mark for most of this week. On Friday, though, the mercury could climb as high as 15°C. In Helsinki, the weather is presently a couple of degrees warmer than usual as a result of Hurricane Kirk tracking toward Europe over the Atlantic.
“To be precise what remains of the hurricane will be absorbed into another low-pressure system over western Europe during the course of Wednesday,” said Koskela.
While Southern Finland is bracing for an autumn storm, Northern Finland is expecting relatively typical winter weather early this week, with forecasts suggesting five to ten centimetres of snow could fall in wide parts of Lapland. The snowfall could also make road conditions challenging for motorists.
On Friday, the warmer air is to stream into the northern regions, likely melting most of the snow that fell at the beginning of the week. Night temperatures are expected to rise above the freezing point in all parts of the country.
September was record-breaking warm in some parts of Finland, according to the Finnish Meteorological Institute (FMI). Weather statistics indicate that the nationwide mean temperature for the month was 12.2°C, matching the all-time high set in September 2023.
“It is unheard of that Finland’s mean temperature for the same month is record high in consecutive years,” Pauli Jokinen, a meteorologist at FMI, stated on 1 October.
Temperatures rose to 25°C on a total of eight days in September, marking an increase of three from the previous record dating back to 1968.
