Tropical Storm 'Koto' is likely to influence the weather across the country's land and sea areas, bringing more frequent showers or thundershowers that may at times be accompanied by gusty winds. This active weather condition is forecast to persist until Sunday. Meanwhile, over Brunei waters, sea condition is at moderate to rough, with wave height of 1 to 3.5 metres. The public, road users, and fishermen are advised to take necessary precautions during the active weather conditions.
