‘Blood rain’ could fall as weather phenomenon reaches Denmark

Winds containing dust picked up in the Sahara Desert could result in an unusual colour of weather in Denmark on Tuesday night.

The phenomenon, known as ‘blood rain’, could reach the Scandinavian country on Tuesday night.

“In large parts of Denmark, but particularly in Jutland, we could wake up to a fine layer of red dust on our cars early tomorrow,” Thomas Mørk, meteorologist with TV2, said.

The red dust is carried to Denmark on a mild westerly wind, Mørk said.

“This air has been blown all the way from Africa, over the Canary Islands and in across the North Sea. It has gathered up dust, and the dust particles have been mixed with raindrops,” he said.

“When the drops evaporate, just the dust will be left, forming a reddish glow,” he added.

Although that sounds exotic, the phenomenon is not actually uncommon in Denmark, according to the meteorologist.

“We see it a couple of times a year. Either in warm summer weather because of wind from Africa, or if a mild wind comes in spring,” he said.

Denmark last saw blood rain in April 2018, but the weather type occurs more regularly in southern Europe.

Temperatures of 3-7°C and a mild wind are forecast by national meteorological agency DMI for Tuesday night.

How much will it snow in Denmark this weekend?

Winter weather arrived in spectacular fashion to coincide with the beginning of December this week. The weekend could bring more snow to parts of the country but probably less disruption than recent days.

Recent snowstorms disrupted North Jutland in particular and Denmark in general, and more cold weather can be expected this weekend albeit severe, according to forecasts.

“We won’t see the Ragnarok-like weather we’ve seen in some places recently again this weekend, but it’s now winter weather and it has also snowed in several places overnight,” said meteorologist Frank Nielsen of the Danish Meteorological Institute (DMI).

Cold weather on Friday and a low front across the North Sea will bring clouds and precipitation across Denmark from the west, Nielsen said.

That will materialise as cold rain or sleet in many areas but probably snow in North Jutland, he said.

“There could be between five and ten centimetres of snow north of the Limfjord,” the meteorologist said, referring to the waterway that cuts across the northern part of Jutland, including main regional city Aalborg.

“In the southern part of the country, an equivalent five to ten centimetres of rain could fall,” he added.

Friday’s temperature will be between freezing point and five degrees Celsius, with the north of the country falling in to the lower end of that range and the south the warmer end.

Mist and fog is forecast this evening, caused by various weather fronts moving over Denmark.

That could still be felt on Saturday morning, though it is likely to be a little warmer at 2-6 degrees Celsius. Mild winds could make that fell chiller, but snow is unlikely.

Sunday will see the temperature drop again, to 0-4 degrees Celsisu. Snow is possible, particularly on eastern coasts.

Strong winds in the east of the country and along the coasts will result in a “rather cold 24 hours,” Nielsen said.

Nighttime temperatures are expected to drop below zero throughout the weekend. Motorists are therefore warned to be alert to icy road surfaces.
