Hydrological forecast Based on the meteorological forecast, the processed hydrological information and the modeled water quantities from NIMH: Danube Basin: Today (10.01) and in the next 3 days the levels of the observed rivers in the basin will increase as a result of precipitation. Significant increases in river levels are expected in the period 10-11.01.2021 in the catchments of the rivers Iskar, Osam, Vit and Yantra. On 12 and 13.01 the river levels in the basin will drain.

As a result of heavy rains there is a danger of torrential floods in the evening of 10.01.2021 and at night against 11.01.2021 in the catchments of:

Iskar River (in the upper and middle course along the main river and in the catchments of Musalenska Bistritsa River, Lakatitsa River, Cherni Iskar River, Malyovitsa River, Urdina River, Levi Iskar River, Lopushnitsa River, Pryaka River , Beli Iskar River, Perlovska River, Vitoshka Bistritsa River, Slatinska River, Suhodolska River);

Rusenski Lom River (in the upper reaches of the Cherni Lom River); Suha Reka River (along the main river and in the catchment area of ​​the Karaman River). The model for the catchment area of ​​the Ogosta River predicts: The forecasted water quantities on 11, 12 and 13.01.2021 will be around the average annual values. Today (10.01) and in the next three days the river levels in the catchment will remain without significant changes. Water quantities will be below the attention thresholds. 
The model for the catchment area of ​​the Iskar River predicts: The forecasted water quantities on 11, 12 and 13.01.2021 will be above the average annual values. As a result of precipitation, today (10.01) and in the next 2-3 days the river levels in the whole catchment will increase significantly. Water quantities will be below the attention thresholds. The model for the catchment area of ​​the Yantra River: The forecasted water quantities on 11, 12 and 13.01.2021 will be above the average annual values. Today (10.01) and tomorrow, as a result of precipitation, river levels will increase throughout the catchment area. On 12 and 13 January 2021, the rivers in the catchment will flow. Water quantities will be below the attention thresholds.
The model for the catchment area of ​​the Rusenski Lom River: The forecasted water quantity in the catchment area of ​​the Cherni Lom River on 11, 12, 13, 14 and 15.01.2021 will be below the average annual value. Today (10.01) and in the next 4-5 days, as a result of precipitation, the river levels in the catchment will increase. The water quantity will be below the attention threshold.
