Cyclone Ditwah has weakened into a deep depression over the southwest Bay of Bengal and continues to track northwards at around 10 kmph, the India Meteorological Department (IMD) said early Monday. The system is expected to lose strength further and downgrade into a depression by Monday noon as it moves along the north Tamil Nadu–Puducherry coasts.
The IMD said the centre of the deep depression was located just 50 km off the Tamil Nadu–Puducherry shoreline in its 2 am bulletin. A red alert had been issued earlier for north Tamil Nadu, Puducherry and adjacent south Andhra Pradesh coasts.
Tamil Nadu’s revenue and disaster management minister KKSSR Ramachandran confirmed that three people have died in weather-related incidents triggered by the cyclone.
