Chennai : Overnight rain left 2cm of rainfall in Nungambakkam and 6mm in Meenambakkam. India Meteorological Department (IMD) has forecast moderate monsoon rainfall for the next two days. Weather bloggers also forecast that night spells could continue for the next few days. “For the next 48 hours, the city and suburbs may receive moderate rainfall with thunderstorms and lightning in some areas. Skies may be partly cloudy, with maximum and minimum temperatures at 33°C-34°C and 25°C-26°C,” the IMD bulletin stated. 

The rainfall is attributed to favourable winds in the region. IMD said that that a cyclonic circulation currently lies over the southwest and westcentral Bay of Bengal off the north Tamil Nadu coast, extending up to 5.8km above sea level and tilting southwestwards. “Night to morning rain will continue on Sunday morning in north Tamil Nadu, and this trend will persist over the next few days for Kancheepuram, Tiruvallur, Chennai, Chengelpet, and other parts of north Tamil Nadu,” blogger Pradeep John said in a post. The IMD has also forecast heavy rainfall for several interior and delta districts in the coming days. On Oct 20, districts like Dharmapuri, Krish nagiri, Salem, Erode, Tirupattur, and Vellore could see heavy rainfall ranging from 6cm to 12cm at isolated locations. Additionally, ghat areas in nine districts, including Coimbatore, Tiruppur, Dindigul, and Nilgiris, may experience heavy spells on Oct 21. Similar weather is expected on Oct 24 in districts such as Ariyalur, Thanjavur, Nagapattinam, Tiruchy, and Perambalur. The IMD previously forecast the development of a lowpressure system over the north Andaman Sea next week, expected to intensify into a depression and move northwest. 

However, weather bloggers believe this system may bypass Chennai and move towards the Andhra Pradesh-Odisha coast. 

Since Oct 1, Nungambakkam has recorded 34cm and Meenambakkam 27 cm of rainfall. The Chennai subdivision has received 32cm of rainfall, which is 187% above the normal amount. During the same period, Tamil Nadu recorded 15 cm, a 70% excess.
