- Tropical Cyclone Senyar made a rare landfall in Aceh, near the border with North Sumatra, on November 26, 2025.
- The cyclone caused major floods and extreme rainfall in the northern parts of Sumatra and the Malaysian Peninsula.
- This event is highly unusual as storms rarely form or make landfall near the equator due to the lack of Coriolis force.
- Cyclone Senyar is the second tropical storm to defy norms, following Typhoon Vamei in December 2001, which formed even closer to the equator.
- Researchers attribute such rare storms to unique atmospheric conditions, such as persistent vortices and strong monsoon winds.
- Aceh experienced widespread heavy downpours, leading to floods and landslides in nine out of 23 regencies/cities.
