The Thai Meteorological Department (TMD) has issued a warning regarding Tropical Storm Danas, which is intensifying the monsoon over Thailand.
Weather forecasts predict heavy rainfall across 38 provinces tomorrow. As of 5pm yesterday, July 5, the TMD announced the sixth warning on Tropical Storm Danas, located in the northern South China Sea at latitude 20.6°N and longitude 117.7°E, with maximum wind speeds near the centre at approximately 83 kilometres per hour.
The Department of Disaster Prevention and Mitigation has cautioned 33 provinces across four regions to prepare for potential flooding, flash floods, and landslides from July 6 to 12. Current weather conditions indicate heavy rain in three regions, affecting 42 provinces, with Bangkok experiencing a 70% chance of rainfall.
The storm is nearly stationary and is expected to approach Taiwan between July 7 and 9, without directly affecting Thailand’s weather. However, it will strengthen the southwest monsoon covering the country. This announcement was made at 5pm yesterday, July 5, with a follow-up expected at 11pm the same day.
The weather forecast today, July 6, predicts heavy rainfall in eastern regions, with some areas experiencing very heavy rain. The northern, upper northeastern, and southern regions will also see significant rainfall.
Residents in these regions are advised to be cautious of heavy and accumulated rain, which could lead to flash floods and overflowing rivers, particularly in foothill areas and low-lying regions. This is due to a low-pressure system over northern Vietnam combined with a moderate southwest monsoon affecting the Andaman Sea, Thailand, and the Gulf of Thailand.
Weather forecast
Sea conditions in the Andaman Sea and the Gulf of Thailand are moderate, with waves in the upper Andaman Sea reaching around 2 metres and 1 to 2 metres in the lower Andaman Sea and the upper Gulf.
