In February 2019, in some of the southern regions of Russia, the dynamics of the winter crops development resembles the situation that was observed in 2018. As in 2018, in 2019, the vegetation of winter crops is much more active in these regions than usual. The detailed analysis of the situation in some regions of the south of Russia indicates that at the beginning of 2018 and 2019, the intensity of winter vegetation, reliably represented by the NDVI index, significantly exceeds the average annual values. It allows us to conclude that the development of winter crops in the southern regions of the European Russia in February 2019 is similar to February 2018. This kind of dynamics may pose a certain threat to further development of the crops, as it can lead to the lack of moisture in the soil at further stages of their development. The analysis, in particular, indicates that, compared to 2018, in the Republic of Crimea the conditions for further development of winter crops are more favorable this year, since in January 2019 a significant amount of precipitation fell and more soil moisture could have accumulated than in 2018. The situation in Stavropol region is different. In this region in January – February 2019 much less precipitation fell than the average annual rate, but the vegetation of winter crops is much more intense than in 2018, when precipitation was rather close to the average annual rate. It significantly increases the risks of further abnormal development of winter crops in the region. The paper also reports that a similar situation was observed in many regions of southern Russia at the end of February. There are regions, where the accumulated precipitation for the period January – February 2019 was significantly less than the average annual values. It increases the risks of further inadequate development of winter crops in such regions and can lead to a decrease in their yield compared to 2018.
