New Low Pressure Area Likely To Form Over Bay of Bengal On October 23

Heavy rain continues to lash parts of Tamil Nadu as the northeast monsoon picks up speed, with the weather department warning of very heavy rain in seven districts today. Good rainfall is currently being recorded in coastal districts, the delta region, and areas near the Western Ghats, while Chennai experienced continuous rain last Saturday. Building on these weather conditions, the meteorological department states that a new low pressure area is likely to form over the southeast and adjoining central Bay of Bengal on the 23rd of this month. This system stems from an upper air cyclonic circulation currently sitting over the Gulf of Thailand and Myanmar. This lower level circulation is expected to move into the north Andaman Sea by tomorrow morning, eventually triggering the formation of the low pressure area over the central Bay of Bengal by the 23rd. Once formed, this new system is expected to move in a west and northwest direction and could strengthen into a depression. Authorities note that whether it will grow further into a cyclone will depend on its strength as it develops, with further updates to follow.

Context

Weather systems forming over the Bay of Bengal are common during the active phase of the northeast monsoon season in South India. Meteorological departments track these upper air circulations closely as they move across regional waters to assess potential rainfall risks and storm development.
