Twin Cyclones Surprise Meteorologists in Bay of Bengal
In late November 2025, two cyclones named Senyar and Ditwah formed in the Bay of Bengal, surprising weather experts.
Senyar was unusual because it started near the Malacca Strait, a rare place for cyclones.
It moved slowly and caused heavy rain in Indonesia and Malaysia.
Ditwah was even slower and brought very heavy rain to Sri Lanka.
Ditwah's path was unique, moving northward from the south of Sri Lanka, something not seen since 1967.
Both cyclones were different from usual patterns, making them special to study.
