A low-pressure area has formed over the Southeast Bay of Bengal at 05:30 hours IST on November 13, 2026, under the influence of an upper-air cyclonic circulation over the central Andaman Sea.
According to the India Meteorological Department (IMD), the system extends up to middle tropospheric levels and is projected to move northwestward, intensifying into a well-marked low-pressure area around November 14 and further into a depression over the same region by November 15.
Simultaneously, an active Western Disturbance persisting as a cyclonic circulation over the Kashmir division is driving wet weather across Northwest India. Additional upper-air cyclonic circulations persist over Sikkim and its neighborhood, the southeast Arabian Sea adjoining south Lakshadweep, and the Gulf of Mannar.
