North Indian Ocean cyclonic storm in 2025

Cyclonic Storm Senyar is an unusual, rare, and deadly tropical cyclone that brought heavy rains to the Malay Peninsula and Sumatra in November 2025. The thirteenth tropical depression and third cyclone of the 2025 North Indian Ocean cyclone season, Senyar developed in 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 cyclone before making landfall on northern Sumatra near midnight on 26 November, and then paralleled the Sumatran coast. Senyar caused heavy flooding and landslides across central and southern Thailand (especially Hat Yai), peninsular Malaysia, and Sumatra, Indonesia, leaving at least 91 people dead, 21 missing, and 58 injured. Millions of people were affected, with tens-of-thousands evacuated across the three countries.

Meteorological history

Map plotting the storm’s track and intensity, according to the Saffir–Simpson scale

Map key

  Tropical depression (≤38 mph, ≤62 km/h)  Tropical storm (39–73 mph, 63–118 km/h)  Category 1 (74–95 mph, 119–153 km/h)  Category 2 (96–110 mph, 154–177 km/h)  Category 3 (111–129 mph, 178–208 km/h)  Category 4 (130–156 mph, 209–251 km/h)  Category 5 (≥157 mph, ≥252 km/h)  Unknown

On 20 November, the India Meteorological Department (IMD) began to track an upper-air circulation in the Strait of Malacca.[1] On 22 November, a low-pressure area formed as a result of the circulation.[2] On 25 November, the low-pressure area intensified into a depression as it moved westwards.[3] The Joint Typhoon Warning Center (JTWC) also issued a tropical cyclone formation alert and designated the system as Tropical Cyclone 04B as it exhibited a partially exposed but well-defined low-level circulation area.[4] Later that day, the depression intensified into a deep depression as convection developed and persisted. However, further development was limited due to its proximity to land.[5][6] The system made landfall on northeastern Sumatra near midnight and began deteriorating due to increasing wind shear.[7] Early on 26 November, the IMD named the system Cyclone Senyar.[8] The system tracked along the coast of Sumatra and weakened, with a small low-level circulation center.[9]

Preparations

The IMD issued a rainfall warning for the Andaman and Nicobar Islands, Tamil Nadu, Puducherry, Kerala and Andhra Pradesh from 25 November to 1 December. Wind warnings for gusts of 55–75 km/h (34–47 mph) were also issued for coastal areas of the Andaman Sea and southeastern Bay of Bengal. The IMD said that the depression was expected to bring minor impacts to these areas, such as minor damage to homes and horticulture.[10]

Thailand and Malaysia

Flooding in Thailand killed 46 people, affected 3.2 million others in 1.13 million homes, and caused flooding in 20 provinces, mainly in the country’s south.[11] with the worst effects seen in Hat Yai, where floodwaters reached up to 2 m (6.6 ft) deep, stranding 7,000 foreign tourists as a result.[12] Flood damage across Thailand was estimated at 11.8–23.6 billion baht (US$366–732 million).[13] Flooding also occurred in Peninsular Malaysia, where 21,000 people were evacuated across 10 states in the country.[14] At least one person was killed in the country.[15]

Indonesia

As Senyar traversed through the Strait of Malacca, it also brought flooding to the Indonesian island of Sumatra. At least 44 people were killed by flooding and landslides in North Sumatra, including 20 in South Tapanuli Regency, 12 in Sibolga[16] 7 in Humbang Hasundutan Regency[17] and 5 in Central Tapanuli Regency.[18] The floods also left 58 injured and more than 15,000 were affected in six areas of the province.[19] In South Tapanuli Regency, 20 people were killed, including 18 in Batang Toru District[20] and 2 more in Sipirok and West Angkola Districts.[21] One Tapanuli resident reported that “dozens” of bodies of flood victims were stored at a makeshift morgue in a community center.[20] At least 21 people were left missing in Sibolga alone.[22] In Aceh, landslides killed nine people in Central Aceh Regency,[23] more than 18,200 people were affected by flooding in East Aceh Regency.[24] One additional fatality also occurred in Agam Regency, West Sumatra.[25]
