Rain forecast for Andaman and South India due to weather adversity forming in Bay of Bengal

According to a report by News18, a new weather system developing in the Bay of Bengal may bring heavy rainfall to the Andaman and Nicobar Islands, Tamil Nadu, and Kerala. The India Meteorological Department (IMD) is currently monitoring this system continuously, although there is still uncertainty regarding where this system will move and make landfall.

According to the extended-range forecast released by the India Meteorological Department on 12 November, cyclonic circulation is being observed at upper levels in the sea around Andaman and its surrounding areas. Due to this circulation, a low-pressure area may form in the South East Bay of Bengal around 13 November. This system will become more distinct around 14 November and may develop into a depression in the central part of the South Bay around 15 November. Subsequently, it may become more powerful while moving towards higher latitudes.

According to the Meteorological Department, widespread rainfall is likely in the Andaman and Nicobar Islands between 12 and 18 November. During this period, heavy rainfall may also occur at different locations on the islands. Port Blair and other island settlements are locations that warrant special attention during the development of this weather system. However, the Meteorological Department has not yet issued any specific city-level cyclone warning or identified the exact location of landfall.

Providing more details regarding this system, the Meteorological Department stated that this system may turn into a depression around 15 November and may subsequently transform into a cyclonic storm during the following week. However, various weather models are not in agreement regarding the potential path of this system and the location of landfall, due to which uncertainty regarding its direction persists.

Regarding the southern Indian states, during the week of 19 to 25 November, there is a possibility of heavy rainfall at various locations on certain days in Tamil Nadu and Kerala. Depending on the final movement of the system, wet weather conditions may arise in major cities such as Chennai, Puducherry, Thiruvananthapuram, and Kochi. It is noteworthy that these cities are taken merely as regional references and are not confirmed locations of direct impact.

In addition, the Meteorological Department has also indicated that rainfall may increase in some parts of East and North-East India towards the end of November.

On the other hand, weather conditions in the Philippines are also being monitored. The Philippine weather agency PAGASA has indicated that one or two more tropical cyclones may enter or form within the Philippine Area of Responsibility (PAR) in the month of November. Additionally, there is a possibility of one or two more cyclones in the month of December. The next system that enters this monitoring area will be locally named 'Thomas'. The Philippines is preparing for potential tropical cyclones before the end of the year, including the potential storm named Thomas. Both these phenomena occurring in India and the Philippines are different, but they indicate the possibility of intense weather activity in the region in the coming week.

The India Meteorological Department (IMD) is an institution under the Ministry of Earth Sciences, Government of India, which functions to provide weather forecasts and warnings. It monitors natural phenomena such as rainfall, temperature, and cyclones in various parts of the country.
