Meteorological history

In late November 2023, a low-pressure area crossed into the Bay of Bengal from the Gulf of Thailand. On December 1, the India Meteorological Department (IMD) said the disturbance had developed into a depression in the South Andaman Sea, and was expected to move towards the northwest while strengthening in the Bay of Bengal. On December 2, the system intensified into a deep depression located about 440 kilometres (270 mi) east-southeast of Puducherry. Thereafter, it intensified into a cyclonic storm, and was assigned the name Michaung by Myanmar.


On December 4, cyclone Michaung reached peak intensity as it approached the coast of Tamil Nadu with winds of 110 kilometres per hour (68 mph), equivalent to a high-end tropical storm on the Saffir–Simpson scale. Michaung moved almost directly northward along the coast. On December 5, the storm made landfall between Nellore and Machilipatnam in Andhra Pradesh, weakening as it moved inland. By December 6, the storm had weakened to a depression over central Andhra Pradesh.

Meteorological data

According to the IMD reports, INSAT-3D satellite imagery on December 5 indicated a cloud mass with broken low to medium clouds and intense convection extending over west-central Bay of Bengal and the coastal region of Andhra Pradesh, spanning from latitude 13.5°N to 17.5°N and longitude 80.0E to 82.5E. The minimum cloud top temperature was recorded at −90 °C (−130 °F). Coastal surface observations from various locations on the coast indicated a maximum wind speed of 60 knots (110 km/h; 69 mph) and a minimum sea level pressure of 988 hectopascals (29.2 inHg). Nungambakkam in Chennai recorded the maximum rainfall of 530 mm (21 in) in the three-day period between December 2 and 4.
