Tropical disturbance 99W has been detected near Indonesia and is being closely monitored. The Meteorology, Climatology, and Geophysics Agency (BMKG) identified the system on Monday, April 28, 2025.
Located in the Pacific Ocean, northeast of North Maluku, the disturbance is moving west. It has maximum sustained winds of 15 knots (28 km/h) and a minimum pressure of 1008 hPa. While not expected to directly impact Indonesia, 99W may indirectly influence weather and sea conditions, with increased convective activity observed nearby.
BMKG forecasts a westward trajectory towards the eastern Philippines over the next 24-72 hours. Slight intensification is expected, but the potential for development into a significant tropical cyclone remains low. The Madden-Julian Oscillation (MJO), equatorial waves, and warm sea surface temperatures are contributing factors to its presence during Indonesia's dry season.
