Tropical Storm Malou headed toward South Korea, where five people died when a cyclone struck last week, the U.S. Navy Joint Typhoon Center said.
Malou was 122 kilometers (76 miles) south of Jeju at 9 a.m. Seoul time today, the center said. The storm is forecast to hit the island before crossing southern regions of the country tomorrow, the center said.
The storm had sustained winds of 74 kilometers per hour and Malou is expected to maintain strength as it reaches Jeju about 3 p.m. local time today, the center said.
The Korea Meteorological Administration issued a typhoon warning for Jeju and surrounding seas, and a heavy rain watch for Ulsan in the southeast of the country, it said on its website.
Last week, Tropical Storm Kompasu killed five people, damaged power networks in Seoul and surrounding provinces and forced the cancellation of flights as it crossed the Korean peninsula on Sept. 2.
Malou, the 10th storm of the northwest Pacific season, is named after a hard, colorful stone used to make souvenirs in Macau, according to the Hong Kong Observatory, which lists names assigned to storms in the northwest Pacific and South China Sea.
