Bangkok: The Meteorological Department has issued a warning of heavy rainfall across several regions of Thailand, advising residents to be vigilant against potential flash floods and mudslides. The affected areas include the North, Northeast, East, and the West Coast of the South, where thunderstorms and heavy rain are anticipated in the next 24 hours.
According to Thai News Agency, the forecast predicts very heavy rain in some parts of the North, Northeast, East, and the West Coast of the South. This adverse weather could lead to flash floods and forest runoff, especially on hillsides near waterways and lowland areas. The monsoon trough moving through the North and upper Northeast, along with a strong southwest monsoon over the Andaman Sea, South, and the Gulf of Thailand, are contributing to these conditions. Farmers are advised to take precautions to protect their crops from potential damage.
Maritime conditions are also expected to be rough, with waves in the Andaman Sea and the upper Gulf of Thailand reaching heights of 2-3 meters, and even higher in stormy areas. In the Gulf of Thailand, wave heights are predicted to be 1-2 meters, escalating in areas with thunderstorms. Sailors are urged to proceed with caution and avoid areas with thunderstorms, while small boats in the Andaman Sea and upper Gulf of Thailand are advised to remain ashore until June 13, 2025.
Additionally, a depression over the upper South China Sea is likely to strengthen into a tropical storm, though it is not expected to move into Thailand.
The regional weather forecast for June 11, 2015, indicates varying levels of thunderstorms across the country. Bangkok and surrounding areas may see thunderstorms in 60% of the region, with temperatures ranging from 26-35 degrees Celsius. The northern region could experience thunderstorms in 70% of the area, with heavy to very heavy rainfall in specific provinces. Similar conditions are expected in the northeastern, central, and eastern regions, with varying percentages of thunderstorm likelihood and corresponding temperature ranges. The southern regions, both east and west coasts, are also predicted to experience thunderstorms, with heavy rainfall in select areas.
