The Brunei Darussalam Meteorological Department is advising the public to take precautionary actions against active weather conditions from Saturday until Wednesday.
The department said occasionally heavy and gusty thundershowers are expected to cross inland areas in the afternoon, and spread to coastal areas at night. Wind speeds may reach up to 50 kilometres per hour during heavy or gusty showers.
The sea state is generally at slight to moderate, between 0.5 to 1.5 metres, said the department.
The department also warned that flash floods could occur, particularly at low-lying and flood prone areas as well as near the river banks during continous heavy rain and during high tide.
The public, road users and fishermen are advised to keep up to date with the latest weather forecast, advisories and warnings issued by the department.
