State meteorologists were warning Friday that the sunny skies over much of Southern Norway were about to be replaced by dark clouds that are likely to burst with heavy rain along the coast, not snow. The abrupt change in the weather was likely to melt the snow already on the ground and create difficult driving conditions.
“We can get between 40 and 50 millimeters of rain” from Friday through Saturday, state meteorologist Bente Wahl told state broadcaster NRK. She and her colleagues predicted that Sørlandet and Østlandet would be hit the hardest, especially Kristiansand and Vest-Agder.
Temperatures were also due to rise quickly, with all the rain likely to melt snow along the coast and even cause some flooding. Wahl also warned of slippery roads through the weekend.
The low-pressure system was moving in from the North Sea and bringing with it unusually mild temperatures that also threatened to ruin skiing conditions in some areas, although more snow was expected at higher elevations. State highway crews issued warnings for slick roads in Agder, Telemark, Vestfold and Østfold counties.
