Meteorological Department’s Weather Forecast for February 24, 2025

Today’s weather: Heavy rain is expected in 48 provinces, including Bangkok, with thunderstorms, strong winds, and hail. The monsoon covering the southern region will bring heavy rainfall to 70% of the area.

24-hour Weather Forecast:

Upper Thailand will experience unstable weather conditions, including thunderstorms, lightning, strong winds, and isolated hail in the northern and northeastern regions. Following this, temperatures will drop by 1-3°C.

Residents in upper Thailand are advised to take care of their health due to changing weather conditions and to be cautious of thunderstorms, strong winds, and possible hail. Additionally, there is a risk of lightning strikes in some areas. It is recommended to avoid open spaces, large trees, weak structures, and billboards. Farmers should take preventive measures to protect their crops from potential damage.

This is due to a new moderate to strong cold air mass from China that has extended to cover the northeastern region and the South China Sea. This is causing southerly and southeasterly winds to bring moisture from the South China Sea and the Gulf of Thailand, which are covering the upper parts of Thailand. Additionally, a westerly wind from Myanmar is moving in and will cover the western parts of northern and upper northeastern Thailand.As for the northeast monsoon and easterly winds covering the Gulf of Thailand, the southern region, and the Andaman Sea, these will intensify, leading to increased rainfall in the southern region, with heavy rainfall in several areas and very heavy rainfall in some locations. The sea waves in the lower Gulf of Thailand will be fairly strong, with waves of 2-3 meters high, and in areas with thunderstorms, waves may exceed 3 meters. The upper Gulf of Thailand will experience waves about 2 meters high, and offshore areas of the Andaman Sea will see waves between 1-2 meters, with waves exceeding 2 meters in stormy regions.

It is advised that all boaters in the Gulf of Thailand and the Andaman Sea exercise caution and avoid sailing in areas with thunderstorms. Small boats in the lower Gulf of Thailand should refrain from going out to sea.
