BANGKOK — 9 July 2026, Thailand’s Meteorological Department has warned that although Typhoon Bavi will not make landfall in Thailand, it is expected to strengthen the southwest monsoon and bring heavy rain and possible flash floods to parts of the country between 10 and 15 July.
The department issued a warning for strong winds and rough seas in the Andaman Sea and the upper Gulf of Thailand, as well as heavy to very heavy rainfall along the western coast of southern Thailand, western parts of the Central Plains and the eastern region during the period.
Five provinces in particular — Ranong, Phang Nga, Kanchanaburi, Chanthaburi and Trat — have been urged to remain alert for flash floods and forest runoff.
Although Typhoon Bavi is not forecast to move directly into Thailand, it will strengthen the southwest monsoon prevailing over the country, resulting in heavy to very heavy rainfall and accumulated precipitation in many areas.
Farmers in affected areas have been advised to prepare their agricultural land to minimise potential damage.
Anchalee Suvachittanont, Director-General of the Department of Agricultural Extension, said farmers in the Central, Eastern and Andaman regions should jointly assess the situation and survey high-risk areas to prepare preventive measures and reduce the impacts of Typhoon Bavi, particularly on 11–12 July, when the southwest monsoon is expected to intensify over Thailand.
Furthermore, the overall forecast for mid-July indicates rainfall coverage of about 60–70% across the country, with nationwide rainfall expected to increase further to around 85% in August. Authorities warned that the prolonged wet conditions could lead to agricultural losses and urged farmers to implement long-term preventive measures in advance.
