Practically stationary near Chennai, the deep depression in the Bay of Bengal — the remnant of Cyclone Ditwah — is expected to bring heavy rain to Chennai and three other districts of North Tamil Nadu.
Despite weakening into a well-marked low-pressure area by Tuesday night, the system maintained its intensity throughout the day. The deep depression, which was earlier expected to move towards the south Andhra Pradesh coast, was caught between two anti-cyclonic circulations.

The RMC said the deep depression over the west-central and adjoining southwest Bay of Bengal remained around 35 km off the north Tamil Nadu and Puducherry coasts.
Under its influence, heavy spells accompanied by moderate thunderstorms with wind speeds of 40–60 kmph have been forecast for Chennai, Chengalpattu, Kanchipuram and Tiruvallur districts.
Schools and colleges in Chennai, Kancheepuram and Tiruvallur remained closed on Tuesday as a precautionary measure in view of intermittent heavy rain and waterlogging.
Meanwhile, Tamil Nadu Revenue and Disaster Management Minister KK SSR Ramachandran told the media that financial compensation of ₹20,000 per hectare would be provided to farmers for crop damage.
According to initial estimates, standing crops in nearly one lakh hectares across the delta districts of Mayiladuthurai, Thiruvarur and Nagapattinam, as well as Pudukkottai, have been inundated following the extremely heavy rainfall triggered by Cyclone Ditwah.
