A meteorologist recommends the use of stud shoes, as the streets are now becoming very slippery in places.
To the metropolitan area there is a mild weather period for the weekend.
The warm air mass flowing from the south raised the temperature to the plus side already on Friday. At the same time, rain areas move to Finland, which rain on the coast as water and sleet.
The warmer weather period of several days also thins and presses the snow cover somewhat. Meteorologist on duty at the Finnish Meteorological Institute Jari Tuovinen however, snow lovers still have nothing to worry about.
“Helsinki-Vantaa had a snow cover of 51 cents today. That amount shouldn’t melt in a few days. “
“About 10-20 percent can be snow cover subsidence and melting,” Tuovinen estimates.
When as the temperature shifts to the plus side, the top surface of the snow layer begins to get wet while becoming heavier and denser. This can cause slipperiness in many places.
“I actually took the studs on in the morning. It wasn’t slippery in the morning yet, but in the afternoon it can be especially in places plowed evenly. Without pins, you can walk with your tongue in the middle of your mouth. ”
The road may also be slippery in places.
“The busier and bigger roads, where asphalt is visible, don’t have a terribly bad situation. They also have a polane formed between the lanes in many places, which you have to be careful with. ”
Next week, the weather will cool again and will likely stay on the frost side.
Cross-country ski trails the worst possible combination is plus degrees, water and wind, says the team manager responsible for Helsinki’s tracks Mircos Kienanen.
With the heat, the melting surface layer of snow becomes icy and at the same time skiing difficult. The same reaction is also caused by rain and sleet. Despite the degrees of plus, the coldness of the snow freezes the surface layer of the snow slippery.
“We are constantly trying to run the trails again. The dry snow then comes out, but quickly freezes again. ”
The thickness of the snow cover and the quality of the snow may vary depending on the location.
“20 cents of stale snow might be a really thick layer, while the same thickness of frost snow is actually really little,” Kienanen says.
Despite this, Kienanen is quite confident that you can ski in Helsinki with natural snow even after a few warmer days.
“Looking at the weather forecast now, fortunately it doesn’t seem too rainy so far.”
Would snow plowed from the streets be helpful in an emergency?
“It can’t be preserved. However, there is always rubbish and sand among them. Snow is sometimes run from ice rinks when it is basically clean. However, the streets are completely blocked, so we may not end up with transport equipment. ”
From January predicted colder than usual. According to meteorologist Jari Tuovinen, it seems that the average monthly temperature will be quite normal in the end.
“In Kaisaniemi, for example, it has been about one and a half degrees colder, but when it comes to a few days of Plus, we will probably end up pretty close to the average.”
Many weather services are currently also forecasting a really cold from February. The reliability of forecasts decreases the further we go from the present moment.
“There may be a period in February that is colder and drier, but in recent years they have crept to stay short. From three to five days, but then they may be really cold days, ”Tuovinen says.
