Today’s weather forecast from the Meteorological Department of Thailand (TMD) warns of increased rainfall across 44 provinces, with heavy rain expected in 70% of these areas. Citizens are advised to be cautious of sudden flooding and flash floods.
The TMD predicted that Thailand will experience increased rainfall, with heavy rain in some areas, particularly in the upper northern region and the western part of the southern region.
This situation arises due to the monsoon trough passing through the upper northern region and upper Laos, extending into a low-pressure area in upper Vietnam. Additionally, the southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand has intensified to a moderate level.
Residents in affected areas are urged to exercise caution as heavy to very heavy rain could lead to sudden flooding and flash floods, especially in slopes near waterways and low-lying regions.
In the Andaman Sea, particularly from Phang Nga province upwards, and in the upper Gulf of Thailand, moderate winds are expected, with waves reaching heights of 1 to 2 metres. In areas experiencing thunderstorms, waves could exceed two metres. Mariners should proceed with caution and avoid navigating in stormy areas.
In the northern region, thunderstorms are expected in 70% of the area, with very heavy rain in some places, including Mae Hong Son, Chiang Mai, Chiang Rai, Lampang, Phayao, Nan, Phrae, Uttaradit, Phitsanulok, and Phetchabun. Temperatures will range from 23 to 26 degrees Celsius (°C) at the lowest to 31 to 35 °C at the highest. Southwest winds will blow at speeds of 5 to 15 kilometres per hour (km/h).
