Chennai: The Indian Meteorological Department stated on Wednesday that the severe depression that emerged in the Bay of Bengal will not intensify into a low depression and will shortly cross the coast, despite a weather notice for portions of Tamil Nadu and Poducherry.
Tamil Nadu’s northeast monsoon is getting worse, which has caused heavy rains to fall continuously in most locations. Depending on the amount of rainfall, numerous districts have received red, orange, and yellow alerts.
A low pressure system emerged over the southwest Bay of Bengal at 5:30 am on October 21 and stayed in the same area as a deep depression at 8:30 am, according to a press statement from the Southern Meteorological Department.
Today (22-10-2025), near the shores of North Tamil Nadu, Puducherry, and South Andhra Pradesh, the IMD predicted that this depression will move in a west-northwesterly path and intensify into a low pressure region over the southwest and adjacent west-central Bay of Bengal.
In the following 12 hours, this depression can continue to deepen and proceed in a west-northwesterly trajectory toward the coasts of South Andhra Pradesh, Puducherry, and North Tamil Nadu, it said.
Similarly, the same regions are still affected by the deep depression that dominated the southeast Arabian Sea yesterday, October 21, 2025. At 5:30 am today, it is expected to move slowly westward and deepen into a depression over the course of the next day, according to the IMD.
The IMD predicts that the depression over the Bay of Bengal would travel westward and cross the coast over the course of the next day, with little chance of intensifying into a cyclonic storm. In a similar vein, it is doubtful that the depression over the Arabian Sea would intensify into a cyclonic storm.
The highest rainfall reported today was 25 cm in Periya Kalapettai, Puducherry, 21 cm in Puducherry, 19 cm in Bacoor, and 19 cm in Vanur and Cuddalore, all of which were caused by this depression.
Tamil Nadu’s Heavy Rains and Relief Activities
Widespread rainfall has been observed throughout Tamil Nadu since the northeast monsoon began on October 16. According to the IMD, throughout the next 24 hours, the low-pressure system will move over the shores of South Andhra Pradesh, Puducherry, and North Tamil Nadu.
Due to the weather pattern, Chennai, Tiruvallur, Chengalpattu, Kanchipuram, and Ranipet districts are expected to see heavy rain on Thursday. The day after tomorrow (October 24) is predicted to bring significant rainfall to the districts of Cuddalore, Chengalpattu, and Villupuram.
The Greater Chennai Corporation has prepared to handle any emergency by keeping personnel and equipment on standby due to the heavy rain expected. At midnight, Deputy Chief Minister Udhayanidhi Stalin personally examined the canal and rainfall drainage dredging. Additionally, he instructed the officials to be prepared for any situation.
“We have been directly on the ground since 4 am to inspect the damage caused by the rain,” Stalin told reporters. In the camps, food has been kept available. Inspections are being carried out in response to social media complaints. I visited the Chennai Corporation control room myself. I will visit those areas myself after hearing various complaints about them.
According to him, the chief minister of Tamil Nadu has dispatched ministers to examine the damage that the rain has created in the impacted districts. “The District Collector has had a conversation with the Chief Minister. We are constantly monitoring the devastation that the rain has inflicted throughout Chennai.
On behalf of the Corporation, relief food has also been given to 1,46,950 residents of low-lying regions in Chennai, such as Perambur and Saidapet. According to officials, the relevant district ministers or ministers in charge are keeping a close eye on the situation in other Tamil Nadu districts and making sure that people living in low-lying areas are housed in secure locations.
How can I get in touch with the control center?
The control center is open around-the-clock. By phoning the helpline number 1913, people can file complaints regarding the harm that the rain has caused in their region.
In the Greater Chennai Corporation, 22,000 people—including officers, engineers, staff, sanitation workers, and 2,149 field workers via the Chennai Drinking Water Board—are working on relief efforts in anticipation of the northeast monsoon.
