The Meteorology, Climatology and Geophysics Agency (BMKG) stated that Tropical Cyclone Senyar, which was on the mainland of Aceh, had become extinct.
However, the former tropical cyclone, which is expected to be in Malaysia in the next few days, will still have an impact in the form of the potential for moderate to extreme intensity rain in the regions of Aceh, North Sumatra, West Sumatra and Riau.

“Ex-Tropical Cyclone “SENYAR” (25 knots, 1005 hPa) is predicted to be on mainland Malaysia in the next few days. This system is moving southeast to east, with intensity predicted to weaken in the next 48 hours,” explained BMKG in its Weekly Weather Prospects for the Period 28 November-04 December.
“However, in the next 24 hours, this system will still have a direct impact in the form of potential rain with moderate to extreme intensity and strong winds in the Aceh, North Sumatra, West Sumatra and Riau regions,” he added.
Apart from that, this former tropical cyclone also has the potential to cause high waves of 2.5-4 meters in the Indian Ocean region west of Aceh to the Nias Islands.
Apart from that, Tropical Cyclone Koto, which is currently predicted to be in the South China Sea East of Vietnam, is likely to be stable in intensity with its movement southwest-west towards the South China Sea.
The existence of this tropical cyclone is predicted to have an indirect impact on the potential for moderate to heavy intensity rain in the Riau Islands region.
Apart from that, this tropical cyclone has the potential to trigger high waves of up to 4 meters in the waters of North Kalimantan, the western Sulawesi Sea, the waters of the southern Anambas Islands, the northern Karimata Strait, the waters of the Bintan Islands to Lingga, the North Natuna Sea, the waters of the Natuna Islands, the waters of Subi Islands to Serasan, and the waters of the northern Anambas Islands.
Previously, Tropical Cyclone Senyar which formed in the Malacca Strait caused an increase in rain intensity in the Aceh, North Sumatra and West Sumatra regions.
BMKG noted that in the period 25-27 November several cities/districts in these areas experienced rain with intensity reaching the extreme category, including North Aceh, Aceh (310.8 mm/day);Medan, North Sumatra (262.2 mm/day);Central Tapanuli, North Sumatra (229.7 mm/day);and Padang Pariaman, West Sumatra (154 mm/day)
The Equatorial Rossby Wave which was observed to be active in the same area as the tropical cyclone also contributed to increasing the intensity of the rainfall.
