India Meteorological Department (IMD) has issued a weather alert predicting heavy to very heavy rainfall across multiple regions of India. A developing Cyclonic Storm over the Bay of Bengal is expected to intensify, bringing strong winds and significant rainfall, particularly along the coasts of Odisha and West Bengal.
Weather Systems at Play
A low-pressure area formed over the east-central Bay of Bengal has now intensified into a depression as of 22nd October. This depression, located about 700 km southeast of Paradip (Odisha), is moving west-northwest at 6 km/h and is expected to evolve into a Cyclonic Storm by 23rd October.
IMD forecasts the system to further intensify into a Severe Cyclonic Storm by the morning of 24th October, potentially impacting the coasts of North Odisha and West Bengal between Puri and Sagar Island.
