Morning Temperatures to Plunge by 10°C Tomorrow; Cold Wave Advisories Issued for Most Inland Areas

Morning temperatures are expected to plummet by around 10°C tomorrow (October 22) compared to today (October 21), with some areas in the northeastern part of Gyeonggi Province and the inland and mountainous regions of Gangwon Province dropping below freezing.

As a result, cold wave advisories have been forecasted for most inland regions.

This cold wave advisory is scheduled to take effect at 9 p.m. today.

Cold wave advisories are issued between October and April when the morning low is expected to drop by 10°C or more from the previous day to 3°C or lower, and remain 3°C or more below the average year-round temperature.

Tomorrow's nationwide morning lows are expected to range from 0°C to 10°C (32°F to 50°F).

Frost is expected to form inland, while ice is likely to form in places such as eastern Gyeonggi Province, the inland and mountainous regions of Gangwon Province, North Chungcheong Province, northeastern North Jeolla Province, and central inland and northern mountainous regions of North Gyeongsang Province, requiring precautions against cold damage to crops.

Daytime highs will hover between 14°C and 19°C (57°F and 66°F).

Citizens should be mindful of large temperature swings of more than 15°C (27°F).

Expected lows and highs for major cities are: Seoul at 5°C (41°F) and 16°C (61°F); Incheon at 3°C (37°F) and 15°C (59°F); Daejeon at 3°C (37°F) and 17°C (63°F); Gwangju at 8°C (46°F) and 17°C (63°F); Daegu at 5°C (41°F) and 17°C (63°F); Ulsan at 7°C (45°F) and 18°C (64°F); and Busan at 10°C (50°F) and 19°C (66°F).

The cold snap is not expected to last long.

Temperatures will stay below seasonal averages until the morning of the day after tomorrow (October 23), before recovering to normal levels starting from the afternoon and maintaining an upward trend thereafter, rising slightly above average by Sunday, October 25.

Strong winds blowing at speeds of 30 to 65 km/h and high waves ranging from 1.5 to 4.0 meters are expected to persist for the time being in the far southern waters off Jeju and the outer far southern waters of the eastern South Sea, where high sea warnings are currently in effect.

In addition, similar high sea conditions are expected to begin in the far southern waters of the southern East Sea this afternoon, and in the front waters of the central East Sea and northern North Gyeongsang Province tonight.
