Rain and very strong winds.
Scotland is expected to be hit the hardest by the low-pressure system that has moved in over the British Isles.
From 10 am to 11 pm, an orange wind warning has been issued in large parts of Scotland by the national weather service Met Office. An orange warning means that there is a risk to life and property.
Local authorities have, among other things, cancelled trains, closed parks and urged citizens to anchor loose objects such as trampolines and outdoor furniture, reports the news agency AP.
According to Met Office, the winds can reach around 140 kilometers per hour, equivalent to almost 40 meters per second.
Orange warning in Norway
At the same time, the storm is hitting Scotland during the most intense tourist period and several popular tourist attractions in Edinburgh are closed on Monday.
In northern England, northern Wales and Northern Ireland, a yellow warning has been issued.
Also in Norway, orange and yellow warnings have been issued for strong storm winds from Oslo via Kristiansand, Stavanger and further up to Bergen, reports NRK.
Approaching Sweden
"Floris" reaches Sweden on Tuesday and is then expected to hit the country's western parts the most. SMHI has issued yellow warnings in large parts of Västra Götaland County and in southern Värmland County.
This low-pressure system will move in towards the West Coast during the evening, but it's mainly during the night towards Tuesday that it will start blowing, said Kristin Sahlström, meteorologist at SMHI, to TT on Sunday.
