SEOUL, August 2 (AJP) - With sweltering heat persisting across the country, South Korea is set to see intense rainfall starting Sunday as back-to-back downpours are expected to sweep much of the country.

The Korea Meteorological Administration (KMA) on Saturday warned that very heavy rain is forecast from Sunday to Monday, particularly across the Seoul metropolitan area, the central provinces of Chungcheong, the southwestern Jeolla region, and southern coastal parts of South Gyeongsang Province.

Some areas could experience torrential downpours of 50 to 80 millimeters per hour, a level of rainfall that could lead to flash floods, road inundation, or landslides, the KMA said.

Another round of heavy rain is forecast for Wednesday and Thursday, as unstable atmospheric conditions are expected to persist throughout the week.

Despite the forecast rain, the blistering heat is unlikely to subside. While temperatures may briefly dip during showers, the KMA said daytime heat indices could rise above 33 degrees Celsius again as soon as the rain stops.

High humidity will continue to push up perceived temperatures, and tropical nights, when temperatures remain above 25 degrees Celsius after sunset, are expected in many regions.
