Heavy Rainfall Will Affect Southeast Russia

It is forecasted that over the next three days（July 9-11, 2025）, influenced by a combination of an upper-level trough and a low-level vortex (Figure 1), parts of the southeastern Russian regions including Chita Oblast and Amur Oblast will experience heavy to torrential rain, with localized extremely heavy downpours. These areas will also be accompanied by severe convective weather such as short-term intense rainfall and thunderstorms with strong winds. The cumulative precipitation in most of these regions is expected to range from 30 to 80 mm, with some areas exceeding 100 mm (Figure 2). Attention should be given to secondary disasters triggered by persistent heavy rainfall, including flooding, landslides, mudslides, and urban waterlogging.
