A heatwave will continue across Seoul and many inland areas of South Korea for the next several days [1].
This weather pattern poses risks to public health and infrastructure as high temperatures combine with atmospheric instability. The persistence of the heat increases the likelihood of heat-related illnesses, while the forecast for severe storms threatens local transportation and safety.
Forecasters expect daytime highs to remain above 30 °C [1] throughout the week. This elevation in temperature is attributed to a persistent high-pressure ridge that is keeping heat trapped over the region [1, 2].
Despite the ongoing heat, atmospheric instability is expected to trigger scattered showers tomorrow [1, 2]. Meteorologists forecast rainfall amounts between five and 30 mm [1]. These showers may be accompanied by thunderstorms, strong gusts, and hail [1].
Residents in Seoul and inland provinces are advised to prepare for these sudden shifts in weather. The combination of high humidity and heat often precedes the type of volatile storm activity forecast for the coming day [2].
“Daytime highs above 30 °C”
The intersection of a prolonged heatwave and sudden, severe thunderstorms indicates a period of high atmospheric volatility. For a densely populated urban center like Seoul, this combination increases the risk of urban flash flooding and puts additional strain on the electrical grid due to peak cooling demands.
