Winds of up to 27 metres/second are gathering in the Baltic and Sea of Bothnia, according to FMI meteorologist Eveliina Tuovinen.
The FMI has issued a warning that waves at sea may surpass seven metres in height.
”We may see record-breaking waves,” said Tuovien, adding that storms like this tend to occur once a year.
Strong winds will also sweep over Finland on Tuesday night, with gusts of 20 m/s in southern and western areas.
Up to 20 cm of snow
On Tuesday afternoon, precipitation was coming down as rain in the south and southwest and as snow elsewhere.
”Ostrobothnia, Pirkanmaa, Central Finland and North Savo may see 10 to 20 centimetres of snow,” she added.
A warning for slippery roads is in force for all of Finland, with the exception of the Uusimaa region.
”Snowy roads and poor visibility are making overtaking difficult, which is why we're warning motorists,” Tuovinen explained.
