According to the National Center for Hydro-Meteorological Forecasting, the Southern Central Highlands and the Southern region will have rain, moderate rain and scattered thunderstorms, locally heavy to very heavy rain with rainfall from 20-40mm, locally over 80mm; warning of the risk of local heavy rain (>80mm/6 hours).
The North will receive two consecutive cold air waves causing rain, decreasing temperatures, turning cold at night and in the morning, and the mountainous areas may be cold at 14 degrees. October 19 is the first cold air wave, but it deviates a lot towards the East Sea, so it only causes showers and thunderstorms in the mountainous areas, and the temperature drop is not significant.
The second wave from October 22-23 will see the cold air intensify, causing thunderstorms and cold weather at night and in the morning. Severe cold in the Northern region is likely to occur widely from the second half of December, similar to the average of many years.
