The national weather bureau is warned of heavy rain and possible flooding as well as forest run-off this week due to the effects of Typhoon Vicente.
The Meteorological Department on Tuesday issued a warning for those living in the northeast, north as well as the eastern provinces of Chanthaburi and Trat and the southern provinces of Ranong and Phang-nga, asking residents to prepare for abundant rain and isolated heavy to very heavy rainfall between today and Friday.
In addition, residents in at risk zones and along waterways should beware of possible flash floods and forest run-off, Thai News Agency reported.
The southwest monsoon over the Andaman Sea, Thailand and the Gulf of Thailand will also gain in strength over the next four days. Stronger winds and waves are expected in the Andaman Sea and the Gulf of Thailand with waves 2-3 metres high. All shipping should proceed with caution and small boats in the Andaman Sea and the upper Gulf of Thailand should keep ashore during the period.
Scattered rain with heavy rainfall in some areas as well as flooding is expected in upper Thailand and some southern provinces resulting from the effects of Typhoon Vicente, which was centred about 60km south of Macau, China.
The tropical cyclone is moving northwestward and was forecast to make landfall over upper Hainan today and move to upper Vietnam on Wednesday.
More than 100 people were injured and trees were uprooted as the typhoon battered Hong Kong.
Hong Kong authorities issued a hurricane warning for the first time since 1999 as Typhoon Vicente roared to within 100km of Hong Kong shortly after midnight.
However, the warning was downgraded to a strong wind warning by mid-morning as the storm passed to the west and weakened over the southern Chinese coast.
The severe typhoon disrupted ferry, bus and train services in Hong Kong while some flights were cancelled with hundreds of passengers being delayed.
Schools and the stock market were closed for the morning but were due to reopen later Tuesday.
