The 17th typhoon of the year will approach Korea and bring heavy rain to southern parts on Friday, the Korea Meteorological Administration forecast on Monday.

Doraji, the name of the typhoon given by North Korea, formed in waters east-northeast of Taiwan around 3 a.m. Monday with a central pressure of 980 hPa and wind speeds of about 18 m/s and was moving northeast.

According to the KMA, there is a 60 percent chance of Doraji passing through the Korea Strait on Friday and a 20 percent chance of it reaching the south coast via waters near Jeju. Or it could veer away toward Japan.

If it passes through the Korea Strait, it is expected to bring a lot of rain, and if it lands on the south coast, rain and gusty winds will affect Gyeongsang provincial areas especially. But if it heads for Japan it will have almost no effect on the Korean Peninsula.

There is also a chance of rain in central parts under the influence of a trough of low pressure, the KMA predicted. Some regions along the path of the typhoon could also see rain this weekend.

There is a possibility that the typhoon will turn into an extratropical cyclone, rapidly losing steam as it approaches Korea.

"We're uncertain which course typhoon Doraji will take d ue to the influence of a trough of low pressure," Kim Sung-mook of the KMA said, urging people to watch the forecasts.

Meanwhile, the June-August period was recorded as the hottest summer in 40 years. According to the KMA, the average temperature nationwide was 25.4 degrees Celsius, up 1.8 degrees from previous years.
