Cyclone Senyar

Cyclonic Storm Senyar, also referred to as Tropical Depression 34W over the northwest Pacific Ocean, was a weak but exceptionally rare and catastrophic tropical cyclone that became the third-costliest tropical cyclone on record outside the North Atlantic basin, behind Storm Daniel and Typhoon Doksuri. Senyar brought heavy rains, causing widespread flooding and landslides to the Malay Peninsula and Sumatra in late November 2025. The thirteenth tropical depression and third cyclone of the 2025 North Indian Ocean cyclone season, Senyar developed over the Strait of Malacca from a low-pressure area that formed on 22 November. The disturbance headed westwards and intensified into a depression and then a deep depression on 25 November. It then further intensified into a cyclonic storm before making landfall on northern Sumatra near midnight on 26 November, and then paralleled the Sumatran coast as it weakened and made a second landfall in Peninsular Malaysia. It was the second tropical cyclone documented in the Strait of Malacca after Vamei in 2001, and the first to form at the area since the beginning of reliable records.
