Tropical Storm Ma-On is forecasted to move North-westwards and Tropical Storm Tokage is forecasted to move North-eastwards, and both tropical storms are expected to move further away from our country.

2. Brunei Weather Situation:

Tropical Storm Tokage will not affect our weather. However Tropical Storm Ma-On will indirectly cause unsettled weather conditions this week especially on 24th and 25th August. Occasional showers or thundershowers are expected to cross land and sea areas, especially at night until early morning. Showers can be heavy and gusty at times with wind speed may increase up to 45 km/h.

Over Brunei waters, sea state is generally slight, between 0.4 to 0.8 m.
