South Korea's weather agency on Sunday issued a heat wave warning throughout much of the nation, with the temperature of some cities in the central region going above 35 C in the afternoon.

The Korea Meteorological Administration said earlier Sunday it has issued a heat wave warning in most parts of the country except Jeju and some coastal areas. The KMA announces a warning when temperatures are likely to stay above 35 C for two consecutive days.

In particular, the central region of the country has been suffering from scorching weather for last three days, with the city of Hanam in Gyeonggi Province becoming the hottest city in the nation after reaching 36.3 C on Friday, the KMA said. The temperatures in other Gyeonggi Province cities were also above 35 C, with Gwangju at 36.2 C and Anseong at 35.7 C.

Seoul's temperature on Thursday was 28.5 C, but it rose to 32.4 C the following day, and 32.7 C on Saturday. Its daytime high was also around 33 C on Sunday. 

The KMA, however, said South Korea's weather is expected to cool down from Sunday evening as Typhoon Nepartak is expected to dump rain across the nation. (Yonhap)
