On the morning of May 6, authorities raised the orange level of frost danger for Moscow and the surrounding region. The city information service Moscow 24 shared the update as frost risk became evident across the metropolitan area.
The official warning stated that freezing conditions would persist from 02:00 to 08:00 on May 6. Forecasts indicated that temperatures would dip to minus 1 degree Celsius within Moscow proper and reach minus 2 degrees Celsius in the Moscow region overall. Residents were urged to take precautions against the cold snap, especially during the early hours when frost was expected to be most intense.
Earlier in the morning, the Hydrometeorological Center of Russia issued a frost advisory for Muscovites and residents of the Moscow region. The window of concern extended from 03:00 to 07:00 in Moscow and from 03:00 to 08:00 for the surrounding area. The communication highlighted the need to safeguard vulnerable plants, outdoor utilities, and unprotected water lines from freezing temperatures during the overnight hours.
As reported by the Moscow region weather bulletin, a prominent forecast observer from the Phobos weather center noted that precipitation and cold air were in play for the early days of May. Forecasts in the bulletin suggested that rainfall or snowfall could accompany the frost, with the possibility of precipitation peaking during the first week of the month. The forecast also indicated that the climate norm would be approached as May progressed into its later weeks. With the transition toward warmer days, residents could expect milder conditions and temperatures climbing toward spring norms, potentially reaching the mid-teens to around 20 degrees Celsius as May advances.
In the days surrounding the frost event, weather services repeatedly emphasized the importance of monitoring hourly updates. Local authorities urged citizens to dress in layers, protect outdoor vegetation, and secure any outdoor plumbing and irrigation lines that might be susceptible to freezing. Community advisories also suggested delaying late-night outdoor activities in exposed spaces and ensuring that cars and outdoor equipment remained shielded from the cold air. The frost episode served as a reminder that even as the calendar shifts toward May, cold nights can still pose risks to gardens, crops, and municipal infrastructure. As climate patterns continue to unfold, residents are encouraged to stay informed with official notices and to prepare for a range of transitional temperatures typical of late spring in the region.
