Published 03.03.2021 RSE "Kazhydromet" from March 1, 2021, regularly provides a weekly hydrological forecast.
In terms of the moisture reserves the plains of the river:
In Karaganda region, the average long-term values are 8-42% lower, in Kostanay region-31-36% less, in West Kazakhstan region-10-44% less, in Atyrau region-19% less. In the Akmola region-more than the average long-term values by 54%, North Kazakhstan region more by 50%, Aktobe region more by 39%,
Indicators of autumn soil moisture:
More than the average long-term values by 26% in the Akmola region; by 36% in the North Kazakhstan region by 16-50 % Kostanay region; 9% of Karaganda region;
It is less than the average long-term values by 14-71% in the river basins of the West Kazakhstan region and by 52 % in the Atyrau region, 20-78% in the Aktobe region, 18% in the Kostanay region, 23-66% in the Karaganda region.
The depth of soil freezing is more than last year's indicators by an average of 9-71 cm in the West Kazakhstan Region, North Kazakhstan Region, Karaganda, Atyrau, Akmola, Kostanay, and Aktobe regions.
Snow reserves in mountain river basins are as follows:
In the mountains of the East Kazakhstan region, the average annual values are 14-16% lower, with the exception of the basin of the left-bank tributaries of the Ertis, where the amount of precipitation is 13% higher than the average annual values.
In the mountains of Zhambyl and Turkestan regions, the average long-term values are 32-88% lower.
In the mountains of Almaty region, the average long-term values are 24-41% lower.
In the case of high temperature background and heavy rains in the month, high talo-rain floods are possible along the mountain rivers of the south, south-east and east of Kazakhstan.
Currently, the process of snow accumulation continues.
According to the weather forecast, daytime temperatures are expected to be positive in Turkestan, Kyzylorda, Almaty and Zhambyl regions in the first decade of March. At the very end of the decade, daytime temperatures are expected to increase to positive values in East Kazakhstan and Karaganda regions.
For decades in the South, South-East of the country precipitation mostly in the form of rain which may lead to melting of snow melt and the formation of slope flows, weakening of the ice phenomena and the formation of ice jams, the rise of the levels and the water outlet on the floodlands of the river.
According to the remote sensing images of NASA satellites processed by RSE "Kazhydromet" as of 27.02.2021, the area of the territory of Kazakhstan covered with snow is 91%.
