Three typhoons, including Typhoon Dolphin, are approaching the Korean Peninsula and are expected to create a combined weather system this weekend [1].

The convergence of these storms represents a complex disaster scenario. Rather than providing relief from drought, the systems are projected to bring extreme heavy rain and intense heat to the region [1].

Meteorologists said the three simultaneous typhoons are a "typhoon legion" [1]. This grouping is expected to drive hot air northward, potentially pushing temperatures in Seoul up to 40°C [2].

While the capital faces extreme heat, other regions will deal with volatile precipitation. The east coast, specifically the Donghae-side, is expected to experience extreme rainfall over the weekend of Aug. 6–7 [3].

Typhoon Dolphin is a primary driver of this weather pattern, pushing hot air into the peninsula while the other two unnamed typhoons flank it [1]. The interaction between these three systems creates a high-risk environment where heat, rain, and drought disasters may overlap [1].

Local authorities are monitoring the situation as the storms move toward the peninsula. The forecast indicates that the region will face extreme rainfall rather than light drizzle [1].

Three typhoons are expected to form a 'typhoon legion'

The simultaneous arrival of three tropical systems creates a compounding disaster effect. By driving extreme heat into the interior while dumping heavy rain on the coasts, the 'typhoon legion' prevents the peninsula from experiencing a balanced weather recovery, increasing the risk of both flash flooding and heat-related casualties.
