-40ºC (-40ºF) frosts to come in Central Russia.
Within 3-5 days, the average daily temperature is expected to be 10-15 degrees below normal. In the north-east district (Kostroma and Ivanovo regions) predicted the strongest -40°C frosts.
In Moscow, the morning temperature will range from -23 to – 28°C, the whole region to -33°C.
The danger is that the low temperature will be accompanied by strong wind (5-10 m/s).
At the weather station “ENEA” January 5 snow depth increased to 22 cm, in the south of the area – up to 30 cm.
The south of the county is less cold (-20 to – 25). But due to strong winds and blizzards it will feel 5-8 degrees lower than actual. The combination of these factors increases the risk of frostbite.
