On Tuesday, May 12, the weather will be generally cloudy across the country, with rain expected in various regions. The capital area and Gangwon Province are forecasted to clear up by nightfall.

According to the Korea Meteorological Administration (KMA) on May 11, rain that begins in the central region and North and South Gyeongsang provinces will expand to South Jeolla Province and Jeju Island starting early in the morning, and to South Gyeongsang Province by mid-morning.

Most areas will see the rain taper off by the afternoon, although South Gyeongsang Province and Jeju Island may experience rain until the evening.

Expected rainfall totals from May 11 to 12 are as follows: 5 to 10 mm in Seoul, Incheon, and northern Gyeonggi Province; 5 to 20 mm in southern Gyeonggi Province; 10 to 50 mm in Daejeon, Sejong, and Chungcheong provinces; 10 to 60 mm in Gwangju, South Jeolla, and North Jeolla provinces; 5 to 40 mm in Busan, Ulsan, Daegu, North Gyeongsang, and South Gyeongsang provinces; and 5 to 40 mm in Jeju Island.

During the rain, residents should be cautious of strong winds, thunder, and lightning. Hail is also possible, particularly in the inland areas of Chungcheong, Jeolla, Gyeongsang provinces, and Jeju Island, so precautions for facilities and crops are advised.

Morning low temperatures are expected to range from 12 to 16 degrees Celsius, while daytime highs will be between 19 and 23 degrees Celsius. Air quality is forecasted to be 'good' across all regions.

Waves in the coastal waters are expected to reach 0.5 to 1.0 meters in the East and West Seas, and 0.5 to 1.5 meters in the South Sea.

In the offshore waters (about 200 km from the coastline), wave heights are predicted to be 0.5 to 1.5 meters in the East Sea and 0.5 to 2.0 meters in the West and South Seas.

The KMA advises that rain will come and go, with significant variations in rainfall amounts even within the same region, and urges residents to refer to real-time weather radar images and the latest weather information.
