Heavy Rainfall and Severe Convective Weather Expected in North-Central Korean Peninsula
Over the next 3 days, influenced by warm and moist southwesterly winds on the northern flank of the subtropical high and weak cold air (Figure 1), north-central parts of the Korean Peninsula will experience moderate to heavy rain, with locally torrential rainfall accompanied by severe convective weather including short-duration heavy rainfall and thunderstorm gales. Accumulated precipitation could reach 50-80 mm, with some areas exceeding 100 mm. Specifically, parts of North Pyongan Province, northern South Pyongan Province, northern and southwestern Chagang Province, and northern Ryanggang Province may see accumulations exceeding 120 mm (Figure 2). The period of intense rainfall is primarily concentrated on July 3-4. Attention should be given to secondary disasters triggered by the heavy rains, including flooding, landslides, debris flows, and urban waterlogging.
