Weather tracker: Warm Yellow Sea makes storms stronger in South Korea

South Korea's prime minister is meeting officials to get ready for a lot of rain this week. Some areas in the central and northern parts of the country might get over 200mm of rain.

There were big storms and heavy rain in South Korea earlier this month. More thunderstorms have arrived and may cause problems. These storms are made stronger by the very warm Yellow Sea. The water there is 29C, which is 4C warmer than normal.

Thailand is also expecting heavy rain during its monsoon season, which lasts until October. In the Philippines, one area called Tarlac is in a state of calamity because of heavy rain in August.

In the north Pacific, there could be new typhoons and tropical storms this week. Last week, two storms, Typhoon Bang-lang and Tropical Storm Etau, appeared near each other but did not hit land. In the eastern north Pacific, Hurricane Karina is heading north of Hawaii. Another storm, Tropical Storm Lowell, might become a hurricane.

Europe had a very hot summer and the warm weather is continuing. The heat will get worse this week in central and southern Europe. Temperatures could be 10C above normal. In Bosnia and Herzegovina, it might reach 40C by the weekend.
